Question

How to use public inheritance in C++

Answer 1

#include <iostream>

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

class Base {
protected:
	int a, b; 
public:
	void set_ab(int _a, int _b) {
		a = _a;
		b = _b;
	}
	void print_ab() {
		cout << a << " " << b << endl;
	}
};

class Derived : public Base {
	int c;
public:
	void set_c(int _c) {
		c = _c;
	}

	void print_c() {
		cout << c << endl;
	}
};

int main()
{
	Derived o;

	o.set_ab(13, 7);
	o.print_ab();

	o.set_c(88);
	o.print_c();

	return 0;
}



/*
run:

13 7
88
