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 program that implements a `Complex` class containing an overloaded `+ operator` that can add two `Complex` objects:
1. A **Complex** and a **double** 
2. A **double** and a **Complex**

# Sample run	 	
Here’s what you should see when you run the program.                        
```txt
a = 1.5  1.3
b = 2.5  2.3
After evaluating c = a + b using + operator: c = 4  3.6
After evaluating d = a + 1.1 using + operator: d = 2.6  1.3
After evaluating e = 1.1 + a using + operator: e = 2.6  1.3
```

# Coding exercise

Your job is to declare a `friend` function in the `Complex` class and define it outside the class.

Implement an overloaded “+” operator using a friend function.
