C++ Comparison Operators
Comparison Operators
Comparison operators are used to compare two values (or variables). This is important in programming, because it helps us find answers and make decisions.
The return value of a comparison is either 1 or 0, which means true (1) or false (0). These values are known as Boolean values, and you will learn more about them in the 布尔值 和If..Else chapter.
In the following example, we use the greater than operator (>) to find out if 5 is greater than 3:
A list of all comparison operators:
| Operator | Name | 例子 | 尝试一下 |
|---|---|---|---|
| == | Equal to | x == y | Try it » |
| != | Not equal | x != y | Try it » |
| > | Greater than | x > y | Try it » |
| < | Less than | x < y | Try it » |
| >= | Greater than or equal to | x >= y | Try it » |
| <= | Less than or equal to | x <= y | Try it » |
You will learn much more about comparison operators and how to use them in a later chapter.
