Categories: Classes and Objects. No Comments on CPP program for illustrating access specifiers

In this article we will learn to implement a CPP program for illustrating access specifiers. A C++ program is provided below for illustrating access specifiers public, private, protected.

 

Program is as follows:

#include <iostream>
using namespace std;
class A
{
	protected:
		int x;
	public:
		A(int p)
		{
			x = p;
		}
};
class B : public A
{
	private:
		int y;
	public:
		B(int p, int q) : A(p)
		{
			y = q;
		}
		void show()
		{
			cout<<"x = "<<x<<endl;
			cout<<"y = "<<y<<endl;
		}
};
int main()
{
	B obj(10, 20);
	//Since show is public in class B, it is accessible in main function
	obj.show(); //x is protected in A so it is accessible in B's show function
	//y is not accessible in main as it is private to class B
	//cout<<obj.y 
	return 0;
}

 

Output for the above program is as follows:

x = 10
y = 20
