00:00:05,230 --> 00:00:07,660
Welcome to this bonus section for the course.

2
00:00:08,260 --> 00:00:15,040
In this section, we'll learn about the basics of C++ enumerations, also known as enumerated data types

3
00:00:15,040 --> 00:00:16,059
or in nums.

4
00:00:17,320 --> 00:00:22,270
Please note that there are some concepts, constructs and techniques that I will use in this section

5
00:00:22,270 --> 00:00:26,740
of the course that you may not have learned yet, depending on how much of the course you've completed.

6
00:00:27,250 --> 00:00:30,910
For example, I'll use the statements which statements?

7
00:00:30,910 --> 00:00:35,290
The range based for loop vectors, functions and overloaded operators.

8
00:00:35,470 --> 00:00:37,380
All of these are covered in the course.

9
00:00:37,390 --> 00:00:42,340
If you haven't already completed those sections of the course, I strongly urge you to complete those

10
00:00:42,340 --> 00:00:44,470
sections before you do this one.

11
00:00:44,710 --> 00:00:48,490
For your reference, vectors are covered in sections seven and 20.

12
00:00:48,760 --> 00:00:50,920
Functions are covered in section 11.

13
00:00:50,920 --> 00:00:53,050
Strings are covered in section ten.

14
00:00:53,260 --> 00:01:00,340
Control structures such as the if else switch and range based for loop are covered in section nine and

15
00:01:00,340 --> 00:01:03,040
operator overloading is covered in section 14.

16
00:01:05,560 --> 00:01:10,330
Enumerated types were first introduced in 1970 in the Pascal programming language.

17
00:01:10,600 --> 00:01:16,360
Since their creation, almost every other language has adopted enumerated data types of some form.

18
00:01:17,080 --> 00:01:20,710
Later, the C programming language introduced the enum keyword.

19
00:01:20,710 --> 00:01:27,100
So in C++, enumerated types were inherited from C and extended in C++ 11 and four.

20
00:01:27,280 --> 00:01:29,180
So what's an enumerated type?

21
00:01:29,200 --> 00:01:35,410
Well, in short, an enumerated type provides a useful way to store a set of named integral constants

22
00:01:35,410 --> 00:01:37,210
known as enumerators.

23
00:01:37,390 --> 00:01:41,170
In order to fully understand the enumerations, we need to take a closer look.

24
00:01:41,200 --> 00:01:47,200
First, we'll see what motivated the creation of enumerated data types and see how they became so popular.

25
00:01:47,230 --> 00:01:52,300
Next, we'll look at the syntax of a C++ enumeration and go through every part of it.

26
00:01:52,420 --> 00:01:56,470
Well then see the difference between scoped and scoped enumerations.

27
00:01:56,740 --> 00:02:02,650
UN scoped enumerations require no name qualification, so they're visible throughout the scope in which

28
00:02:02,650 --> 00:02:04,270
the enumeration is defined.

29
00:02:04,360 --> 00:02:10,539
Scoped enumerators do require a name qualification and so they can be accessed only using the scope

30
00:02:10,539 --> 00:02:11,830
resolution operator.

31
00:02:11,980 --> 00:02:17,170
Finally, we'll head over to the ID and see some of the most common uses of enumerations.

32
00:02:17,560 --> 00:02:22,270
Before we get started, remember I'm only covering the basics of C++ enumerations.

33
00:02:22,300 --> 00:02:27,730
Now let's head over to the next video to see what motivated the creation of enumerated data types and

34
00:02:27,730 --> 00:02:29,350
how they're used in C++.
