Exercise: The Calculator Object

Problem Statement

In this exercise, you have to implement the calculator type and create the cal object from it. Your calculator will perform four basic tasks:

• Addition

• Subtraction

• Multiplication

• Division

Each function will take two floats as parameters. These floats will not be values of the object. Instead, they’ll be specified in the function calls.

Make sure that cal is a closed object.

Sample Input

cal#add(10.0, 5.0);

cal#subtract(10.0, 5.0);

cal#multiply(10.0, 5.0);

cal#divide(10.0, 5.0);

Sample Output

15.0

5.0

50.0

2.0

Coding Challenge

Below, you must write code for the calculator type as well as the calculator object. Remember that the names of all the functions must be identical to the ones in the Sample Output. Furthermore, these functions should be public and must only handle floats.

Take some time to flesh out the logic behind this problem before jumping to the actual implementation. It isn’t very tricky if you understand the concepts we’ve covered in this section.

If you feel stuck, you can always refer to the solution review in the next lesson.

Good luck!
