1
00:00:05,900 --> 00:00:08,500
C++ has a rich set of operators

2
00:00:08,500 --> 00:00:10,700
that can be used to build up expressions.

3
00:00:11,300 --> 00:00:14,400
Most of the c++ operators are binary operators,

4
00:00:14,400 --> 00:00:16,800
which means they operate on two operands.

5
00:00:16,800 --> 00:00:19,300
For example, the multiplication operator.

6
00:00:19,900 --> 00:00:20,800
However,

7
00:00:20,800 --> 00:00:24,600
some are unary operators, which means they operate on only one operand.

8
00:00:24,600 --> 00:00:29,300
An example of this is the unary minus operator, which simply negates its operand.

9
00:00:31,000 --> 00:00:34,400
There's even a ternary operator that operates on three operands.

10
00:00:34,400 --> 00:00:35,900
This is the conditional operator.

11
00:00:36,800 --> 00:00:40,700
The c++ common operators can be grouped into several categories.

12
00:00:41,200 --> 00:00:44,700
Assignment operators are used to modify the value of some object

13
00:00:44,700 --> 00:00:46,300
by assigning a new value to it.

14
00:00:47,180 --> 00:00:51,780
Arithmetic operators are used to perform mathematical operations on operands.

15
00:00:52,880 --> 00:00:55,380
The increment and decrement operators are interesting

16
00:00:55,380 --> 00:00:59,280
because part of them work like an assignment and part of them work like arithmetic.

17
00:00:59,940 --> 00:01:02,480
They're super useful and very commonly used.

18
00:01:03,880 --> 00:01:06,380
Relational operators or comparison operators

19
00:01:06,380 --> 00:01:08,980
allow you to compare the values of two objects.

20
00:01:09,380 --> 00:01:12,180
These are very useful and include equal to

21
00:01:12,180 --> 00:01:14,980
not equal to less than greater than and so forth.

22
00:01:15,780 --> 00:01:20,280
The logical operators are used to test for logical or Boolean conditions.

23
00:01:20,280 --> 00:01:23,500
For example, if you want to execute a specific statement

24
00:01:23,500 --> 00:01:27,300
only when the temperature is less than freezing and it isn't snowing, 

25
00:01:27,700 --> 00:01:31,500
these include the logical not, and, and or operators.

26
00:01:32,160 --> 00:01:35,760
There are also several member access operators.We've already seen one of them.

27
00:01:35,760 --> 00:01:38,060
Remember, the array subscript operator.

28
00:01:38,060 --> 00:01:40,760
It allows access to a specific member.

29
00:01:40,760 --> 00:01:45,020
There are others that work with objects and pointers,which we'll cover later in this course.

30
00:01:45,020 --> 00:01:47,270
Finally, there's the other category.

31
00:01:47,270 --> 00:01:51,470
This includes those operators that really don't fit very well into the previous categories.

32
00:01:52,070 --> 00:01:54,570
In the next several videos, we'll head over to CodeLite

33
00:01:54,570 --> 00:01:57,570
and see some examples of these operators in live code.
