To find the size of variable,  sizeof operator is used i.e sizeof(dataType).

 
 

Here is source code of the C++ Program to Find Size of Int Float Double and Char data types. The C++ program is successfully compiled and run(on Codeblocks) on a Windows system. The program output is also shown in below.

SOURCE CODE : :

/*  C++ Program to Find Size of Int Float Double and Char data types  */

#include <iostream>
using namespace std;

int main()
{
    cout << "Size of char: " << sizeof(char) << " byte" << endl;
    cout << "\nSize of int: " << sizeof(int) << " bytes" << endl;
    cout << "\nSize of float: " << sizeof(float) << " bytes" << endl;
    cout << "\nSize of double: " << sizeof(double) << " bytes" << endl;

    return 0;
}

Output : :

/*  C++ Program to Find Size of Int Float Double and Char data types  */

Size of char: 1 byte

Size of int: 4 bytes

Size of float: 4 bytes

Size of double: 8 bytes

Process returned 0
