Big array gives segmentation error in C

Question

I am really new to C, so I am sorry if this is a absolute beginner question, but I am getting a segmentation error when I am building large array, relevant bits of what I am

Answer 1

You are most likely getting a stack overflow, since you are creating a very large array on the stack. To avoid this, allocate the memory dynamically:

unsigned long long *numbs = malloc(arr_size * sizeof(unsigned long long));

Later, when you are finished with the array, free it again:

free(numbs);
