why is the answer 100 in the following code ? Please help me out !

Question

#include <iostream>
using namespace std;

int main()
{
int numbers[100];
cout << sizeof(numbers) / sizeof(numbers[0]);

return 0;
}

Answer 1

sizeof of an int = 4 bytes, you have an array of 100 ints so you have 400 bytes total, divided by sizeof of one int which 4. 400/4=100.
