A segmentation fault error with 2D array

Question

There is a weird segmentation fault error. The following code runs fine

#include  
#include 
main()
    {
    int matrixSize = 100         


        

Answer 1

You are exceeding the stack size most likely.

In the terminal you are using to run this, try typing

ulimit -s unlimited

and re-run, assuming you are on a Linux system using bash (or sh).

If you have to use arrays that size, you can make them dynamic so they are on the heap rather than the stack if changing the stack size is problematic for some reason.
