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 to maintain complex numbers. Also, provide an overloaded **+ operator** in it that can add two complex numbers and make a provision to add a complex number with a double using the same overloaded operator. In this addition, the double value should be taken as the real value of the complex number and the imaginary value should be treated as 0.

## 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
```

## Coding exercise 

Your job is to overload the `+ operator` in the code widget given below.
