Using char array inside union

Question

I'm able to print the address and values of ints but not the chars of the union.Why is that so

#include <iostream>

using namespace std;

union Endian
{
    int i;
    char c[sizeof(int)];
    int j;
};

int main(int argc, char *argv[]) {
    Endian e;
    e.i = 20;
    cout << &e.j;
    cout << &e.i;
    cout << &e.c[0]; //Why can't I print this address
    cout << e.c[1]; // Why can't I print this value

}
