#include <iostream> 

using namespace std; 

 

int main() 

{ 

  char ch; 

  int i; 

 

  cout << sizeof ch << ' '; // size of char 

  cout << sizeof i << ' ';  // size of int 

  cout << sizeof (float) << ' '; // size of float 

  cout << sizeof (double) << ' '; // size of double 

 

  return 0;
