#include <iostream>
#include <cstdlib>
#include <ctime>
int main ()
srand(time(nullptr));
int arr[ ] = {1, 2, 3, 4, 5};
std::cout << arr[rand()%5];
return 0;
}

Zeke, won't that possibly go out of bounds?
arr[5] <<<<

@jay it shouldn't because the remainder of a devision by 5 can never be greater than 4.
