Go - 赋值运算符
下表列出了 Go 语言支持的所有赋值运算符 -
运算符 | 描述 | 示例 |
---|---|---|
= | 简单赋值运算符,将右侧操作数中的值分配给左侧操作数 | C = A + B 会将 A + B 的值分配给 C |
+= | 添加 AND 赋值运算符,将右操作数添加到左操作数,并将结果分配给左操作数 | C += A 等同于 C = C + A |
-= | Subtract AND 赋值运算符,它从左操作数中减去右操作数并将结果分配给左操作数 | C -= A 等同于 C = C - A |
*= | 乘以 AND 赋值运算符,它将右操作数与左操作数相乘,并将结果分配给左操作数 | C *= A 等同于 C = C * A |
/= | Divided AND 赋值运算符,它将左操作数与右操作数相除,并将结果分配给左操作数 | C /= A 相当于 C = C / A |
%= | 模 AND 赋值运算符,它使用两个操作数取模并将结果分配给左操作数 | C %= A 相当于 C = C % A |
<<= | 左移 AND 赋值运算符 | C <<= 2 与 C = C << 2 相同 |
>>= | 右移 AND 赋值运算符 | C >>= 2 与 C = C >> 2 相同 |
&= | 按位 AND 赋值运算符> | C &= 2 等同于 C = C & 2 |
^= | 按位排斥 OR 和赋值运算符 | C ^= 2 与 C = C ^ 2 相同 |
|= | 按位包含 OR 和赋值运算符 | C |= 2 与 C = C |2 |
例
请尝试以下示例来了解 Go 编程语言中可用的所有赋值运算符 -
package main
import "fmt"
func main() {
var a int = 21
var c int
c = a
fmt.Printf("Line 1 - = Operator Example, Value of c = %d\n", c )
c += a
fmt.Printf("Line 2 - += Operator Example, Value of c = %d\n", c )
c -= a
fmt.Printf("Line 3 - -= Operator Example, Value of c = %d\n", c )
c *= a
fmt.Printf("Line 4 - *= Operator Example, Value of c = %d\n", c )
c /= a
fmt.Printf("Line 5 - /= Operator Example, Value of c = %d\n", c )
c = 200;
c <<= 2
fmt.Printf("Line 6 - <<= Operator Example, Value of c = %d\n", c )
c >>= 2
fmt.Printf("Line 7 - >>= Operator Example, Value of c = %d\n", c )
c &= 2
fmt.Printf("Line 8 - &= Operator Example, Value of c = %d\n", c )
c ^= 2
fmt.Printf("Line 9 - ^= Operator Example, Value of c = %d\n", c )
c |= 2
fmt.Printf("Line 10 - |= Operator Example, Value of c = %d\n", c )
}
当您编译并执行上述程序时,它会产生以下结果——
Line 1 - = Operator Example, Value of c = 21
Line 2 - += Operator Example, Value of c = 42
Line 3 - -= Operator Example, Value of c = 21
Line 4 - *= Operator Example, Value of c = 441
Line 5 - /= Operator Example, Value of c = 21
Line 6 - <<= Operator Example, Value of c = 800
Line 7 - >>= Operator Example, Value of c = 200
Line 8 - &= Operator Example, Value of c = 0
Line 9 - ^= Operator Example, Value of c = 2
Line 10 - |= Operator Example, Value of c = 2
Line 2 - += Operator Example, Value of c = 42
Line 3 - -= Operator Example, Value of c = 21
Line 4 - *= Operator Example, Value of c = 441
Line 5 - /= Operator Example, Value of c = 21
Line 6 - <<= Operator Example, Value of c = 800
Line 7 - >>= Operator Example, Value of c = 200
Line 8 - &= Operator Example, Value of c = 0
Line 9 - ^= Operator Example, Value of c = 2
Line 10 - |= Operator Example, Value of c = 2
