How can I increase stack size in c++?

When i compile my code for 100000 input array it doesn't give any error. However, when I increase input to 500000 it gives error about stack overflow. I need to increase stack size. How can I do it?

The answer to the question is to check your compiler's documentation. There's often an option for setting maximum stack size. The default is usually quite small, because well-structured programs have a tree-like call structure, and so the stack take grows logarithmically with program size and complexity. You don't need much stack for a normal program.

As others have said, however, the real answer is probably to move the data off the stack and onto the heap.

Don't rely on large arrays with automatic storage duration. The C++ standard does not mandate a limit on the size of such arrays, but most implementations have a surprisingly small limit compared to the amount of memory that you can allocate with alternative approaches.

In your case, a std::vector<T> where T is the element type, would be appropriate.
