Write program to get the size of basic data types

Hint

The sizeof operator can be used to determine the number of bytes occupied in memory for a certain type.

For example, sizeof(short) is equivalent to 2.

Demo

#include <iostream> 
using namespace std; 
int main() /*  w ww  .  j a  v  a 2  s .  co m*/
{ 

   cout << "\nSize of Fundamental Types\n" 
        << "  Type           Number of Bytes\n" 
        << "----------------------------------" << endl; 
   cout << "  char:           " << sizeof(char) << endl; 
   cout << "  short:          " << sizeof(short)<< endl; 
   cout << "  int:            " << sizeof(int)  << endl; 
   cout << "  long:           " << sizeof(long) << endl; 
   cout << "  float:          " << sizeof(float)<< endl; 
   cout << "  double:         " << sizeof(double)<<endl; 
   cout << "  long double:    " << sizeof(long double) 
         << endl; 

   return 0; 
}

Result
