Profiling means performance measurement.Usually in analysis and design of algorithms we use term profiling.Profiling gives actual time taken by the system to execute the algorithm and sizeof the algorithms.

What is the use of procedure overriding
When do we use that procedure overriding
inbox4rakesh
- Jan 7th, 2008
So far I know. In OOPS there is nothing like Procedure Overriding. However, you have method (function) overriding. If the question is about method overriding then the answer would be:Method overriding is used to add to or replace the functionality of the base class virtual method.

Array Address
Is it possible to change the address of an array?
kamal7725
- Nov 30th, 2007
No, not all. And i don't see any condition in which i need to change the address of the array.This is because if we allow to change the address of the array, there is no way get that memory address again, and memory leak would be there.

What is global constructor?
kamal7725
- Nov 29th, 2007
Global constructors and destructors in C++ have to be handled very carefully to meet the language specification. Constructors have to be called before the main function. Destructors have to be executed after it returns.The answer of this question is static variables.

How to find the size of a class
Size of a class which isclass C{ int i;char c;}int size is 4 and char is 1 but the size of class is coming 8, give the explanation for that?
kamal7725
- Nov 29th, 2007
This is because, your machine is 32 bit( 4 byte). your structure has two variable, a int and a char. int is 4byte long, so no problem. but char is 1 byte long, and will occupy the other 3 byte for alignment. So the sizeof operator gives the total size 8 byte.
