   cin >> op;

   cout << "Enter two operands: ";

   cin >> num1 >> num2;

   switch(op)

   {

       case '+':

           cout << num1+num2;

           break;

       case '-':

           cout << num1-num2;

           break;

       case '*':

           cout << num1*num2;

           break;

       case '/':

           cout << num1/num2;

           break;

       default:

           // If the operator is other than +, -, * or /, error message is shown
