C++ Program to demonstrate sizeof operator

Program

#include<iostream>
using namespace std;
int main()
{
   cout << "Size of char:\t\t" << sizeof(char) << endl;
   cout << "Size of int:\t\t" << sizeof(int) << endl;
   cout << "Size of short int:\t" << sizeof(short int) << endl;
   cout << "Size of long int:\t" << sizeof(long int) << endl;
   cout << "Size of float:\t\t" << sizeof(float) << endl;
   cout << "Size of double:\t\t" << sizeof(double) << endl;
   cout << "Size of wchar_t:\t" << sizeof(wchar_t) << endl;
   return 0;
}

Output

Size of char:		1
Size of int:		4
Size of short int:	2
Size of long int:	4
Size of float:		4
Size of double:		8
Size of wchar_t:	4
