Go - 关系运算符
下表列出了 Go 语言支持的所有关系运算符。假设变量A 为 10,变量B 为 20,则 -
运算符 | 描述 | 示例 |
---|---|---|
== | 检查两个操作数的值是否相等;如果相等,则条件为真。 | (A == B) 不为真。 |
!= | 检查两个操作数的值是否相等;如果值不相等,则条件为真。 | (A != B) 为真。 |
> | 检查左操作数的值是否大于右操作数的值;如果大于,则条件为真。 | (A > B) 不为真。 |
< | 检查左操作数的值是否小于右操作数的值;如果小于,则条件为真。 | (A < B) 为真。 |
>= | 检查左操作数的值是否大于或等于右操作数的值;如果大于或等于,则条件为真。 | (A >= B) 不为真。 |
<= | 检查左操作数的值是否小于或等于右操作数的值;如果小于或等于,则条件为真。 | (A <= B) 为真。 |
示例
尝试以下示例以了解 Go 编程语言中可用的所有关系运算符 -
package main import "fmt" func main() { var a int = 21 var b int = 10 if( a == b ) { fmt.Printf("Line 1 - a is equal to b\n" ) } else { fmt.Printf("Line 1 - a is not equal to b\n" ) } if ( a < b ) { fmt.Printf("Line 2 - a is less than b\n" ) } else { fmt.Printf("Line 2 - a is not less than b\n" ) } if ( a > b ) { fmt.Printf("Line 3 - a is greater than b\n" ) } else { fmt.Printf("Line 3 - a is not greater than b\n" ) } /* Lets change value of a and b */ a = 5 b = 20 if ( a <= b ) { fmt.Printf("Line 4 - a is either less than or equal to b\n" ) } if ( b >= a ) { fmt.Printf("Line 5 - b is either greater than or equal to b\n" ) } }
编译并执行上述程序时,会产生以下结果 -
Line 1 - a is not equal to b Line 2 - a is not less than b Line 3 - a is greater than b Line 4 - a is either less than or equal to b Line 5 - b is either greater than or equal to b
