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 to create a `Sample` class as a Singleton class. A **Singleton class** is a class from which only one object can be created.

## Sample run	 	                        
If you correctly do the coding exercise and don’t change anything in the `main( )` function, then you should expect to see the following console output:

```txt
0x20014c70
0x20014c70
0x20014c70
```
