Determining the Size of Variable Types

  
#include <iostream>

int main()
{
   using std::cout;

   cout << "The size of an int is:\t\t" << sizeof(int)    << " bytes.\n";
   cout << "The size of a short int is:\t" << sizeof(short)  << " bytes.\n";
   cout << "The size of a long int is:\t" << sizeof(long)   << " bytes.\n";
   cout << "The size of a char is:\t\t" << sizeof(char)   << " bytes.\n";
   cout << "The size of a float is:\t\t" << sizeof(float)  << " bytes.\n";
   cout << "The size of a double is:\t" << sizeof(double) << " bytes.\n";
   cout << "The size of a bool is:\t" << sizeof(bool)   << " bytes.\n";
