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 持有 10,变量 B 持有 20,则 −

运算符 描述 示例
== 检查两个操作数的值是否相等;如果是,则条件变为 true。 (A == B) is not true.
!= 检查两个操作数的值是否相等;如果值不相等,则条件变为 true。 (A != B) is true.
> 检查左操作数的值是否大于右操作数的值;如果是,则条件变为 true。 (A > B) is not true.
< 检查左操作数的值是否小于右操作数的值;如果是,则条件变为 true。 (A < B) is true.
>= 检查左操作数的值是否大于或等于右操作数的值;如果是,则条件变为 true。 (A >= B) is not true.
<= 检查左操作数的值是否小于或等于右操作数的值;如果是,则条件变为 true。 (A <= B) is true.

请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" )
	 	}
	 	
	 	/* 让我们更改a和b的值 */
	 	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
