Size of class

Write a program to find the size of a class.

#include<iostream>
using namespace std;
class A
{
	private:
		int d;
		static int x;
};
int A :: x = 10;
int main()
{
	A obj;
	cout << "Size of class A = " << sizeof(A) << endl;
	cout << "Size of obj = " << sizeof(obj) << endl;
	return 0;
}

Output

Size of class A = 4
Size of obj = 4
