Lesson26and27

If you’re looking to sharpen up your C++ programming skills, then you’re in the right place. You will start with learning about dynamic memory allocation, how to create classes, and constructors. 

In the latter half of the course, inheritance, functions, I/O, exception handling, and more. Throughout the course, you will study over 90 carefully designed examples aimed to enhance your understanding of the C++ language.  

By the time you finish this course, you will be able to use more advanced functionality in your C++ programs.

C++ Programming for Experienced Engineers

# Challenge

Write a `Number` class that maintains an `int`. It should have the following member functions defined **outside** this class to perform various operations on the `int`:

- `void setNumber ( int n )` stores the value of `n` in the class' member variable

- `int getNumber( )`  returns the current value of the `Number` class member variable

- `void printNumber( )`  prints the value of the `int` member variable

- `bool isNegative( )` checks whether the value of the `int` member variable is negative

- `bool isDivisibleBy ( int n )` checks whether the `int` member variable is divisible by `n`

- `int absoluteValue( )` returns the absolute value of the member variable


# Coding exercise

Your job is to define the methods outside the `Number` class given below.

Learn to implement a class with member methods defined outside it.
