Menu Driven Programming in C++ using Class with Example

                      In this post, we will see Menu Driven Programming in C++ using Class with Example.

Applications:

1. Better User Interaction

2. Reusability

 

How to implement:

By using

1. Looping Statements

2. Switch Statement 

Program Code:

#include<iostream>

using namespace std;

class Calc

{

public:

    void show_Choices()

    {

        cout << "MENU" << endl;

        cout << "1: Addition " << endl;

        cout << "2: Subtraction" << endl;

        cout << "3: Multiply " << endl;

        cout << "4: Divide " << endl;

        cout << "5: Exit " << endl;

        cout << "Enter your choice :";

    }

    float addition(float num1, float num2)

    {

        return num1 + num2;

    }

    float subtraction(float num1, float num2)

    {

        return num1 - num2;

    }

    float multiply(float num1, float num2)

    {

        return num1 * num2;

    }

    float divide(float num1, float num2)

    {

        return num1 / num2;

    }

};

int main()

{

    Calc obj;

    float x, y;

    int choice;

    do

    {

        obj.show_Choices();

        cin >> choice;

        switch (choice)

        {

        case 1:

            cout << "Enter the two numbers: ";

            cin >> x >> y;

            cout << "The Sum is " << obj.addition(x, y) << endl;

            break;

        case 2:

            cout << "Enter the two numbers: ";

            cin >> x >> y;

            cout << "The Difference is " << obj.subtraction(x, y) << endl;

            break;

        case 3:

            cout << "Enter the two numbers: ";

            cin >> x >> y;

            cout << "The Product is " << obj.multiply(x, y) << endl;

            break;

        case 4:

            cout << "Enter the two numbers: ";

            cin >> x >> y;

            cout << "The Quotient is " << obj.divide(x, y) << endl;

            break;

        case 5:

            break;

        default:

            cout << "Invalid Input" << endl;

        }

    }

    while (choice != 5);

    return 0;
