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
