31. Square of a Number

 Your task is to define both:

• A macro called SQUARE(x) that returns the square of x.
• An inline function called square(int x) that also returns the square of x. 

In main(), the program will read an integer n and call both versions to print:

Macro Square: <result>
Inline Square: <result>

Example
 Input:

5

Output:

Macro Square: 25
Inline Square: 25

Input:

-3

Output:

Macro Square: 9
Inline Square: 9
