Why are values in the array printed even though I passed an iterator bigger than the array?

Question

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

for (int i = 0; i < 5; i++){

cout << b[i] << endl;

}
}

//output 11, 45, 62, 70, 88

that makes sense but if I try..

}
}

//output 11, 45, 62, 70, 88, 0, 8, 7.....

where did the other values come from?

Answer 1

You are accessing unused memory. luckily you are getting because that memory is free otherwise you will get segmentation fault. Try a loop for 1k iteration and check.
