Thread: overloading

Eh...looks fine to me.

Code:

#include <iostream>

using std::cout;
using std::endl;

class A
{
public:
	int m_a;

	A& operator=(const A& a)
	{
		m_a = a.m_a; //assign
		return *this;
	}
};

class B : public A //B derived from A
{
public:
	int m_b;

	B& operator=(const B& b)
	{
		this->A::operator=(b); //call base operator=
		m_b = b.m_b; //assign
		return *this;
	}
};

int main()
{
	A a1, a2;
	B b1, b2;
	a1.m_a = 2;
	a2 = a1;

	cout << a2.m_a << endl;

	b1.m_a = 3;
	b1.m_b = 4;

	b2 = b1;

	cout << b2.m_a << " " << b2.m_b << endl;
 
	return 0;
}
