Heap and Stack

Hi, do you mean that the thing store in heap will stay there as long as it can be unless you remove them explicitly; and for the thing store stack will be remove automatically once you access it?

Correct.

Another description from: http://blogs.wwwcoder.com/govinda/archive/2004/08/16/688.aspx

Stack and Heap:
Both of 'em are sources from which memory is allocated. Stack is automatic, which is created when memory is in scope, and destroyed when it is out of scope. Heap is manual and created and destroyed when requested. On stack, the local variables (unless they are static or register data members), function parameters are stored on stack. On heap normally global variables, static local variables, any data allocated by using calls like new, malloc, calloc etc. memory allocation calls.

William, if you're after an abstract definition of a stack & heap, then please ignore this post.. But if you have a particular context, then perhaps we can provide a simpler and more suitable definition ...

(e.g., the "Java Heap").

Thanks for all the reply:-)

InteractiveMind,  I would like to hear about the definition in Java context.

So, how about Java Stack? Is it only use for recursive call?

Hi, InteractiveMind,

Thanks, this gave me a more "concrete" view of heap and stack.
My last question is,
1)Is this practise apply to C++ and VB also?
2)How the Non Object Oriented language(like C etc) make use of heap?

I'm afraid that my understanding of lower-level programming is limited, so I could not give you a definite answer.
[Stack's as data types are certainly used in C, C++, and VB though]

Sorry

Thanks:-)

--> 1)Is this practise apply to C++ and VB also?

Assuming you are talking about stack processing, yes, all languages that make use of stacks are processed LIFO.


--> 2)How the Non Object Oriented language(like C etc) make use of heap?

These are used to store your variables or varaible that may be needed by the system.

See:

for more information.

Are they using heap to store object, and static variable those kind of things also?
