Re: strange problem with OOP

I wrote this program:

#include <iostream>
using namespace std;
class sample
{
        private:
                int age;
                float salary;
                char status;
};
int main()
{
        sample s1;
        cout << "sizeof int = " << sizeof(int) << endl;
        cout << "sizeof float = " << sizeof(float) << endl;
        cout << "sizeof char = " << sizeof(char) << endl;
        cout << "sizeof sample class = " << sizeof(sample) << endl;
        cout << "sizeof sample class object = " << sizeof(s1) << endl;
        return 0;
}

Got this strange output:

sizeof int = 4
sizeof float = 4
sizeof char = 1
sizeof sample class = 12
sizeof sample class object = 12

Isn't it strange. I am using GCC 4.1.1. Isn't it should be 9 for the
last two one.
