Answer 1

Since you have not mentioned the language, I am coding in C++.

Exercise 1

# include <iostream>

using namespace std;

int main()

{

    float a, b;

    char c;

    cout << "Enter the Operator : ";

    cin >> c;

    cout << "Enter the Operands : ";

    cin >> a >> b;

    switch(c)

    {

        case '+':

            cout << a+b;

            break;

        case '-':

            cout << a-b;

            break;

        case '/':

            cout << a/b;

            break;

        case '*':

            cout << a*b;

            break;

        default:

            cout <<"Invalid Operator";

            break;

    }

    return 0;
