Re: How to calculate the stack and heap size

Hi,

How can we calculate the stack and heap size requried by a C program.
Is there any specific formula used?


There is no standard way to calculate the stack size required, since
1) The C standard does not require a stack
2) You can't tell whether local variables will have memory associated at
   all, they might just be kept in registers or the compiler may find a
   way to eliminate some all together
3) There could be any or no padding between parameters

You can estimate it if you know how your implementation does things, although if you use recursion this can be very difficult.

There is no standard way to determine how much heap us used because
1) The C standard does not require a heap
2) Different heap management schemes have different overheads
3) It depends on how good your implementation is at reusing freed memory

Again, if you know your implementation well enough it may be possible to estimate this.

Please suggest.

I suggest that you ask somewhere dedicated to your system since it is highly system specific. This suggestion is for your benefit as much as ours.
