Program Listing

calculator.cpp

#include <iostream>

using namespace std;

int main()

{

    char opt;

    float num1, num2;

    cout << "\t Switch Calculator in C++";

    cout << "\n\n";

    cout << "\t Enter an operator (+, -, *, /): ";

    cin >> opt;

    cout << "Enter two operands: ";

    cin >> num1 >> num2;

    cout << "\n\n";

    

    switch (opt) 

    {

        case '+':

            cout <<"\t " << num1 << " + " << num2 << " = " << num1+num2;

            break;

        case '-':

            cout << num1 << " - " << num2 << " = " << num1-num2;

            break;

        case '*':

            cout <<"\t " << num1 << " * " << num2 << " = " << num1*num2;

            break;

        case '/':

            cout <<"\t " <<num1 << " / " << num2 << " = " << num1/num2;

            break;

        default:

              cout << "\t Error! operator is not correct. Try Again";

            break;

    }

    

    cout << "\n\n";
