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

## Problem

Design a class called `Rectangle` containing data members `top`, `left`, `bottom`, and `right` to represent its coordinates. Implement the following functions in the _Rectangle_ class.

**areaPeri( )**:	
Calculates and sets the area and perimeter of `Rectangle` in the reference parameters passed to this method

**topLeft( )**:	Returns the `top-left` point of the rectangle

**bottomRight( )**:	Returns the `bottom-right` point of the rectangle

**centerPoint( )**:	Returns the `center` point of the rectangle

**deflateRect( )**:	Decreases the `width` and `height` of the rectangle equally from all sides using the `x` and `y` parameter passed to this function. After _deflateRect( )_, the center remains the same

**inflateRect( )**:	Increases the `width` and `height` of the rectangle equally from all sides using the `x` and `y` parameter passed to this function. After _inflateRect( )_, the center remains same

**equalRect( )**:	Determines whether a rectangle is equal to another

**height( )**:	Calculates the `height` of the rectangle

**width( )**:	Calculates the `width` of the rectangle

**isRectEmpty( )**:	Checks if the rectangle is empty (width and/or height = 0)

**isRectNull( )**:	Determines whether all data members are all equal to 0

**ptInRect( )**:	Checks if a specified point lies within the rectangle

**setRect( )**:	Sets the dimensions of the rectangle

**setRectEmpty( )**:	Sets the rectangle to an empty rectangle (all coordinates 0)

**size( )**: Calculates the size of the rectangle

**intersectRect( )**: Sets the rectangle equal to intersection of two rectangles

**unionRect( )**: Sets the rectangle equal to union of two rectangles

## Coding solution	
Here is a solution to the problem above.
