What should I do when there is not enough memory to run my program in C?

How can I allocate a 2D array using double pointers?

I used VB 2012 Express to make a maze program.

It works really well even when I set ROW*COLUMN to 499*499, (the maze is an array: unsigned char maze[ROW][COLUMN]).

But one time I tried to make a super-giant maze of999*999, and the compiler gave me a "stack overflow" error.

I do know what it means, but is there any way to assign extra memory or even use some disk space to run my program?

Solution

  • You are allocating maze on the stack, and stack size is typically limited to between 1 and 8 megabytes. To overcome this limitation, allocate maze on the heap.
