Character address size, "sizeof"

[castik]

I get 4 bytes as the answer for each?
Why is the byte size of each address the same?

#include<iostream>
using namespace std;
int main () {

int a;
char b;
double c;

cout<< sizeof &a<< endl;
cout<< sizeof &b<< endl;
cout<< sizeof &c<< endl;

return 0;
}

Thanks/ Kirk

You are getting the size of the address, not the actual type.

#include<iostream>
using namespace std;
int main () {

int a = 100;
char b;
double c;

cout<< sizeof a<< endl;   // remove address-of operator
cout<< sizeof b<< endl;
cout<< sizeof c<< endl;

return 0;
}
