What options do you mean?
I C/C++ you have fully control over memory, so you can do what you want.
There is no garbage-collector or some other "hidden" stuff.

i am under impression that when you run a c/c++ program the runtime will
allocate some maximum memory for the program beyond which it cannot exceed.
Is this right?

Normally the memory is only allocated if you are requesting it (for
example by calling "new" or "malloc").

But in general there is a maximum memory which could be allocated. But
this is not specific to C7C++; this also true for all other languages...
If the OS resources are exhausted, then you cannot allocate more memory...

No. There are obviously a few limitations, but they are mainlyWindo

No, The limitations you will get are because of Windows, not because of C++
runtime. The main limitations are :

- You've got 2GB to hold all your data : code, stacks, heaps, etc..

- A thread stack has a maximum fixed size (most often, 1 MB).

Java has a runtime (VM) that offers the possibility to specify the max.
memory usage for it's Garbage collected heap, native C++ programs do not
have such a runtime, Visual studio 2003/2005 "managed" C++ programs however
do have a similar runtime as Java, so, question is - what runtime or what
C++ language are you talking about?
