Why does an array of size 5 shows a random number of 7digits when we print b[8]

Question

I tried to change the default code.

#include <iostream>
using namespace std;

int main()
{
int b[] = {11, 45, 62, 70, 88};

cout << b[0] << endl;
// Outputs 11

cout<< b[3] << endl;
// Outputs 70
cout<< b[8] << endl;

return 0;
}

Waiting for answer

Answer 1

Because if you shoot past an array, you hit another spot of computer memory, where something else may be stored.

(Don't do it.)
