Program to create a simple calculator using switch case.

#include <iostream>

using namespace std;

int main()

{

    float num1, num2,sub,add,multi,divi;

    int choose;

    cout << "Enter the values\n";

    cin >> num1 >> num2;

    while (1)

    {

        cout << "\n\nChoose the options\n1)Add\n2)Sub\n3)Multiplection\n4)Division\n5)Exit\n\n";

        cin >> choose;

        switch (choose)

        {

        case 1:

            add = num1 + num2;

            cout << "Addition = " << add;

            break;

        case 2:

            sub = num1 - num2;

            cout << "Subtraction = " << sub;

            break;

        case 3:

            multi = num1 * num2;

            cout << "Multiplection = " << multi;

            break;

        case 4:

            divi = num1 / num2;

            cout << "Division = " << divi;

            break;

        case 5:

            return 0;

            break;

        default:

            cout << "Invalid option  ";

            break;

        }

    }

} 

Output:

Enter the values 30 20 Choose the options 1)Add 2)Sub 3)Multiplection 4)Division 5)Exit 1 Addition = 50 Choose the options 1)Add 2)Sub 3)Multiplection 4)Division 5)Exit
