I am not understanding the output of this ,

#include <iostream>
using namespace std; 

// pointers and arrays 
char ch1 = 'a' ,  ch2= 'b';

char ch3[6] = {'c', 'd', 'e', 'f', 'g' , 'h'};

char *ptr[3]; 

int main ()
{
    ptr[0] = &ch1 ;

    ptr[2] = ch3;
    cout << &ch1 << endl;
}   

The out put is abcdefgh .

isn't &ch1 supposed to give the address of ch1 ? I cannot make sense why the output should be abcdefgh.
