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 -
操作员 | 描述 | 例子 |
---|---|---|
== | 它检查两个操作数的值是否相等;如果是,则条件成立。 | (A == B) 不正确。 |
!= | 它检查两个操作数的值是否相等;如果值不相等,则条件成立。 | (A != B) 为真。 |
> | 检查左操作数的值是否大于右操作数的值;如果是,则条件成立。 | (A > B) 不正确。 |
< | 检查左操作数的值是否小于右操作数的值;如果是,则条件成立。 | (A < B) 为真。 |
>= | 它检查左操作数的值是否大于或等于右操作数的值;如果是,则条件成立。 | (A >= B) 不正确。 |
<= | 检查左操作数的值是否小于或等于右操作数的值;如果是,则条件成立。 | (A <= B) 为真。 |
例子
尝试以下示例来了解 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" ) } }
当您编译并执行上述程序时,它会产生以下结果 -
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
