Write a program that will demonstrate private member function

Write a program that will demonstrate private member function. The program that uses the following properties - class name- xyz, integer type private member variable- m, n. One private member function getvalue(), two public member function - int mul(), show(). mul() function will call private member function getvalue() for input number m, n and multiply the inputted value m, n like int s=m*n. show() function will display the multiplication value s as output.

#include <iostream>

using namespace std;

class xyz

{

private:

                int m,n;

                void getvalue(void);

public:

                int mul(void);

                void show(void);

};

void xyz :: getvalue(void)

{

                cin >> m >> n;

}

int xyz :: mul(void)

{

                getvalue();

                int s=m*n;

                return(s);

}

void xyz :: show(void)

{

                cout << mul();

}

int main()

{

                xyz m;

                m.show();

                return 0;

}
