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

#include<iostream>
#include<stdlib.h>
using namespace std; 
template<class T, class U>
class A  
{
    T x;
    U y;
};
 
int main()  
{
   A<char, char> a;
   A<int, int> b;
   cout << sizeof(a) << endl;
   cout << sizeof(b) << endl;
   return 0;
}
