16. What Is The Use Of Friend Function?
Sometimes a function is best shared among a number of different classes. Such functions can be declared either as member functions of one class or as global functions. In either case they can be set to be friends of other classes, by using a friend specifier in the class that is admitting them. Such functions can use all attributes of the class which names them as a friend, as if they were themselves members of that class.
A friend declaration is essentially a prototype for a member function, but instead of requiring an implementation with the name of that class attached by the double colon syntax, a global function or member function of another class provides the match.

Here are three basic types of runtime errors in PHP:
Notices: These are trivial, non-critical errors that PHP encounters while executing a script – for example, accessing a variable that has not yet been defined. By default, such errors are not displayed to the user at all – although you can change this default behavior.
Warnings: These are more serious errors – for example, attempting to include() a file which does not exist. By default, these errors are displayed to the user, but they do not result in script termination.
Fatal errors: These are critical errors – for example, instantiating an object of a non-existent class, or calling a non-existent function. These errors cause the immediate termination of the script, and PHP’s default behavior is to display them to the user when they take place.
Internally, these variations are represented by twelve different error types

91. So If Md5() Generates The Most Secure Hash, Why Would You Ever Use The Less Secure Crc32() And Sha1()?
Crypto usage in PHP is simple, but that doesn’t mean it’s free. First off, depending on the data that you’re encrypting, you might have reasons to store a 32-bit value in the database instead of the 160-bit value to save on space. Second, the more secure the crypto is, the longer is the computation time to deliver the hash value. A high volume site might be significantly slowed down, if frequent md5() generation is required.

1. What Types Of Pneumatic Conveying Systems Are Typically Used?
Essentially, there are two types of pneumatic conveying systems. In dilute phase systems, the solids are suspended in the carrier gas and transported to their destination. In dense phase systems, the solids-to-gas ratio is much higher. The gas in these systems acts more like a piston to push the product to its final destination.
Dilute phase systems are more typical than dense phase systems because they can employ positive pressure displacement or a vaccum system. Dense phase conveying is useful if the product degrades easily (works at lower velocities) or is particularly abrasive.
2. What Is The Most Common Carrier Gas Used In Pneumatic Conveying?
While many applications utilize air as a carrier gas, others are not suited for using air. For example, if the substance being conveyed reactions with moisture in the air or if there is a threat of dust explosions, nitrogen is likely choice.
Digital Electronics Interview Questions
3. What Are Some Common Problems Associated With Dense Phase Pneumatic Conveying?
Dense phase pneumatic conveying, typically experiences one common problem from system to system: plugging in the line due to a malfunctioning booster valve.
Dense phase systems require these booster systems to introduce new, pressurized air. These boosters are nearly always accompanied by a check valve. If the check valve becomes stuck, the product is allowed to plug the line.
4. What Are Some Common Problems Associated With Dilute Phase Pneumatic Conveying?
Probably the most common problem encountered in dilute phase pneumatic conveying is the wearing of the rotary valve that serves as an air lock where the product is introduced into the system. If excess air is allowed to pass by the rotary valve, this can cause bridging of the material the flow can be slowed or stopped.
5. Why Would You Use Hydraulics Rather Than Pneumatics?
Hydraulics is suitable for higher forces & precise motion than pneumatics. This is because hydraulic systems generally run at significantly higher pressures than pneumatics systems. Movements are more precise (repeatable) because hydraulics uses an incompressible liquid to transfer power whilst pneumatics uses gases.
Pneumatic systems have some advantages too. They are usually significantly cheaper than hydraulic systems, can move faster (gas much less viscous than oil) and do not leak oil if they develop a leak.
Catia v5 Interview Questions
6. How Can You Prevent Bridging In A Dilute Phase Pneumatic Conveying System?
Manufacturers of these systems recommend bin agitation or blowing air into the top of the feeding bin. These methods can prevent fine particle from bridging near the rotators valve. Two types of particles that are especially prone to bridging include titanium dioxide and calcined- kaolin clay.
7. What Is A “saltation Velocity” And How Is It Used In Designing Pneumatic Conveying Systems?
In designing, the saltation velocity is used as a basis for choosing the design gas velocity in a pneumatic conveying system. Usually, the saltation gas velocity is multiplied by a factor, which is dependent on the nature of the solids, to arrive at a design gas velocity.
For example: the saltation velocity factor for fine particles may be about 2.5 while the factor could be as high as five for course particles such as soybeans could.
Steam Turbine Interview Questions
8. What Is The Practical Particle Size Limit For Pneumatic Conveying?
As a rule, pneumatic conveying will work for particles up to 2 inches in diameter with a typical density. By “typical density
9. What Is Pneumatic Conveying?
Pneumatic conveying is a method of moving bulk solids from one place to another with the help of a carrier gas. A differential pressure is applied inside a conveying line. The flow always moves from a region of higher to lower pressure.
Steam Boilers Interview Questions
10. What Are The Differences Between Pneumatics And Hydraulics?
Working fluid: Pneumatics use air, Hydraulics use Oil
Power: Pneumatic power less than hydraulic power
Size: P components are smaller than H components
Leakage: Leaks in hydraulics cause fluid to be sticking around the components. In pneumatics, air is leaked into the atmosphere.
Pneumatics obtain power from an air compressor while hydraulics require a pump
Air is compressible, hydraulic oil is not
11. Where Pneumatic System Is Used?
Any system needs redundancy in work needs pneumatics, because the compressor of the pneumatic system has periodical operations (intermittent work, not as hydraulic pump). The compressed air could be accumulated in tanks with high pressures and used even if the compressor failed.
Pheumatic system is use in an application where the load is light. Because if the load is heavy, pheumatic system should not be use & hydraulic system should be use instead.
Analogue electronics Interview Questions
12. How Are The Pneumatic System And The Hydraulic System Similar?
Pneumatics use gases such as air or nitrogen, hydraulics use oil or water, both systems use pressure to act on a specific application.
Digital Electronics Interview Questions
13. What Is A Pneumatic System?
Pneumatic system is a system that uses air to power something. For instance, have you seen the tube systems at bank drive-up tellers? Air is used to push the tubes back and forth from the teller to the customer.
14. Why Would Some Industries Select Pneumatics Over Hydraulic?
Actually, there is need for air reservoir in industrial pneumatics systems. Hydraulics can handle more powerful applications than pneumatics for the same overall dimensions, or can be more compact for the same power.

11. Explain Do You Know How The Dose For Children Is Being Estimated Based On Preclinical Data?
There are a number of ways of estimating children’s doses from preclinical (adult) data – often depends on the therapeutic index of the drug in question (the wider the therapeutic window the less accurate the child’s dose needs to be). Sometimes straight weight-basis i.e. 7kg child gets 1/10 dose of 70kg adult. More accurate (so they say) is a dose based on body surface area (child’s surface area is greater in proportion to its body weight than an adult is).
There are normograms to calculate surface area from weight and height of child. All of these may be wrong if clearance of drug in child is significantly different from adult e.g. different metabolism or different route of clearance.
1. What Are Different Types Of Variables In The Application Engine Peoplecode?
There are two types of Variables mainly in Application Engine Peoplecode, they are:
Local variable – These are the variables available for the duration of the program in which they are declared.
Global / Component – These are the variables available while the Application Engine program is running. They get saved at commits and check points, so they can be used for restarts. Component variables are same as Global in case of the AE.
2. Different Ways Pass Data Between The Steps?
We can pass data between steps in three different ways, they are :
Using State records – One row can be passed and can have many state records.
Using Component/Global People code variables
Using Temporary records – Multiple rows of data can be passed.
People Soft Interview Questions
3. What Is Prerequisite For The State Record?
To use state record, there are certain prerequisites, they are:
State Record should be a SQL Table or a Derived work record, for AE Restarts we would definitely need State Record as a SQL Table, as Derived work records store data only at run-time.
Name of the State Record should end in AET, the system identifies the record as a state record with this notation
We need to use PROCESS_INSTANCE field in the record and it should be defined as a key
Any data types except character or numeric must not be required fields
4. How To Read The Run Control Parameters In Ae?
There are many ways of reading run-control parameters in AE, most commonly used are:
SQL:
%Select (EMPLID) /*This will pass value to State record*/
Select EMPLID from PS_AERUNCONTROL where PROCESS_INSTANCE = %PROCESS_INSTANCE and OPRID= %OPRID
People code:
&SQL = “Select EMPLID from PS_AERUNCONTROL Where PROCESS_INSTACNE = RECORD.PROCESS_INSTANCE and OPRID = %Bind (PROCESS_INSTANCE)

PeopleCode Interview Questions
12. How Do You Program Ae Program For The Restarts?
Program Level:
State Record: One of the state record needs to SQL Table, Since All Derived work record will be re-initializing on commit.
Program Properties: On the Advanced tab in the program properties dialog box, make sure that disable restart is not checked
Configuration manager: In the configuration manager, sure that Disable restart is not selected on the process scheduler tab.
Section Level Section type:
The option for section type are prepare only and critical updates
If the section is preparing data i, e select data, populating temporary tables, or updating temporary tables then the section should be prepare only
If the section is updating the permanent application tables in the database, you should select critical update.
Step Level Add an order by clauseThe only restriction for batch runs occurs when you have restart enabled, and you are inside a Do Select that is of the Select/Fetch type (instead of “Re-select” or “Restartable”). with select/Fetch, all commits inside the loop are ignored, including the commit frequency if it’s set.
People Soft Interview Questions
13. Explain Set Processing?
Set Processing uses SQL to process groups, or sets, of rows at one time rather than processing each row individually. With row by row processing you following a repetitive loop that selects a row, determines if it meets a given criterion, if so, apply rule x to row Update row, commit. With set processing, you only select those rows that meet the filtering criteria and then run the rule once again all the affected rows.
14. What Are The Advantages Of Set Processing?
Improved Performance: – Set processing performs significantly better than it is -by-row counterpart for “reasonable” batch processing volumes.
Minimized SQL Overhead : – It tends to use fewer Application Engine SQL statements that each processed more data than the statements executed in row-by-row processing.
Easy Maintenance : – if need to make a fix or add an enhancement to SQL, it’s just a matter of modifying the SQL or inserting the new “Chunk”. Leveraging the RDBMS: – With Set – based processing, you take advantage of the SQL processing engine on the database rather than placing the processing burden and overhead on the application executable.
15. Explain About Testing And Debugging Application Engine?
Application Engine Trace File- You can track the step execution of your application execution
Application Engine Interactive Debugger – First click on the trace tab and turn off the statement timings.

Peoplesoft Hrms Interview Questions
18. What Are The Different Types Of Temporary Tables?
Dedicated
Un Dedicated (Shared)
Manual Testing Interview Questions
19. Why Parallel Processing Required?
Multiple temporary tables as a pool of tables will be helpful to achieve parallel processing. Each invocation of your program would have to allocate an unused temporary table, mark it as ‘in use’, use it and release it back to the pool when you through with it (for each Application Engine program you write).
20. How Running Ae Program As Batch Differs From Running It Online?
Application Engine programs are designed for two types of execution and each has its own pool of Temporary Tables
Online: Invoked by CallAppEngine from People Code Run quickly, synchronously, and at random times. Potential for simultaneous executions Uses the online Temporary Table pool. Not restart able. Psae.exe randomly assigns an instance number from the number range on your online temp tables. If the instance number is in use psae.exe puts the program in Queue until the assigned instance becomes free. Unlock on completion, on Crash free from Manage Abends.
Batch: Invoked through the Process Scheduler. Run for longer amounts of time, asynchronously, and at scheduled times. Can be designed for parallel execution for performance. Uses the Batch/Dedicated Temporary table. Restart able. It allocates instance number based on the availability on a record by record basis and psae.exe begins with the lowest instance numbers. If the properties are set continue – Base table is used with Process instance as key. If Re-startable – Locked across Restarts until completes successfully. If not Re-startable on Program completion.
21. What Are The Important Steps For Implementing The Parallel Processing?
Define you Temporary Tables.
Set the Temporary Tables Online pool.
Assign Temporary Tables to your Application Engine program in it program.
Set Temporary Table Batch Pool – Instance count in the AE.
Build / Rebuild your Temporary Table record.
Code %Table Meta – SQL as reference to Temporary Tables in your Application Engine program,
so that Application Engine can table references to the assigned Temporary Table instance dynamically at runtime.
22. What Happens When All The Instance Of The Temporary Table Is In Use?
It behaviour can control by AE developer. If the runtime options are set to continue
“People Tools will insert rows into the base table using the PROCESS_INSTANCE as a key”
If temp table doesn’t contain PROCESS_INSTANCE as a key field in a Temporary table, you should change the
Temp table runtime options to “Abort” in the appropriate Application Engine programs.
23. How Can You Divide The Data To Be Processed By Different Instance Of The Program To Perform Parallel Program?
Run control parameters passed to each instance of the AE program enable it to identify which input rows “belong” to it, and each program instance inserts the rows from the source table into its assigned temporary table instance using %Table.
24. What Is The Difference Between Exit (0), Exit (1) When We Are Using This Functions In Ae?
Exit (1) causes immediate termination of a Peoplecode program. Use this parameter to rollback database changes.
Exit (0) caused immediate termination of a Peoplecode Program but don’t make rollback in the database.
25. What Is The Difference Between The %select And %selectinit Meta Sqlfunctions?
%select: if any values have not selected then previous value will be there
%selectinit : if any values have not selected then previous value will reinitiate to null
26. What Is The Maximum Limitation On Temporary Table Instances In Ae.?
99
27. What Are Different Types Do Select?
Select/Fetch: Opens the cursor only at the first time and retrieve rows one at loop
Reselect: It opens the cursor and closes the cursor on each iteration of the loop. It will reselect the same row of data. Logic in Actions of the step should be such that it will be changing the status of the rows in the table the do select is selecting. Commits are not ignored and will be committed in a reselect loop when the restart is enabled
Restart able: similar to select/Fetch but it WILL COMMIT inside the loop thus allowing the checkpoint to the PS_AERUNCONTROL table.
Structured Query Report (SQR) Interview Questions
28. Error Handling Or Exception Handling In Application Engine?
Step properties:-
On Error: –
Abort – Write message to message log and terminate.
Ignore – Write message to message log and continue.
Uppress – No message will be written, but program will continue.
People code Action: –
On return options can used to handle run time errors.
Abort: – Exits immediately – Not recommended.
Break: – Exits the current step and section and control returns to the calling step.
Skip Step: – The program exits the current step, and continues processing at the next step in the section. If this is the last step in the section, the calling step resumes control of the processing.
SQL Action properties: –
No Rows: – When the Sql doesn’t return any rows, you can tell what application engine program should do.
Abort: -Program terminates Section Break: -Application Engine exits the current section immediately, and control returns to the calling step.
Continue: – The program continues processing Skip Step: – Application Engine exits the current step immediately and moves on to the next step.
When using skip step keep the following in mind:1) Application Engine ignores the commit for the current step at runtime2) If the current step contains only one Action, only use skip step at by-pass the commit.
29. Which Actions Are Mutually Exclusive And Why They Are Mutually Exclusive?
Sql and callsection.
30. What Is The Main Purpose Of The Access Property In The Section?
Basically they have two option, public and private if section declared as public then it be access from other program. Private we cannot call from other program.
