Question

How to use multiple inheritance to inherit two base classes in C++

Answer 1

#include <iostream>

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

class Base1 {
	int a;
public:
	Base1(int _a) {
		a = _a;
	}
	int get_a() {
		return a;
	}
};


class Base2 {
	int b;
public:
	Base2(int _b) {
		b = _b;
	}
	int get_b() {
		return b;
	}
};


class Derived : public Base1, public Base2 {
	int c;
public:
	Derived(int _a, int _b, int _c) : Base1(_a), Base2(_b) {
		c = _c;
	}

	void print() {
		cout << get_a() << ' ' << get_b() << ' ' << c << endl;
	}
};

int main()
{
	Derived o(3, 6, 9);

	o.print();

	return 0;
}



/*
run:

3 6 9
