My code is super simple:

int main(){
   int n; cin >> n; int arr[1000001][3] = {};
    return 0;
}

I don't understand why it's crashing. My computer couldn't find a contiguous block of memory for this thing or what?

stack space is relatively small – Cruz Jean Jan 11 '20 at 20:19
try using heap memory: int main() { int n; cin >> n; int* arr = new int[1000001][3]; ... return 0; } – edwinc Jan 11 '20 at 20:31
