Simple Calculator using switch Statement

The * operator entered by the user is stored in op. And, the two operands, 1.5 and 4.5 are stored in first and second respectively.

Since the operator * matches case '*':, the control of the program jumps to

printf("%.1lf * %.1lf = %.1lf", first, second, first * second);
This statement calculates the product and displays it on the screen.

To make our output look cleaner, we have simply limited the output to one decimal place using the code %.1lf.

Finally, the break; statement ends the switch statement.
