What will be the output of the following C++ code?

#include <iostream>
using namespace std;
int main ()
{
    int numbers[5];
    int * p;
    p = numbers;  *p = 10;
    p++;  *p = 20;
    p = &numbers[2];  *p = 30;
    p = numbers + 3;  *p = 40;
    p = numbers;  *(p + 4) = 50;
    for (int n = 0; n < 5; n++)
       cout << numbers[n] << ",";
    return 0;
}
