Go - 算术运算符
下表列出了Go语言支持的所有算术运算符。假设变量A为 10,变量B为 20,则:
操作员 | 描述 | 例子 |
---|---|---|
+ | 添加两个操作数 | A + B 得出 30 |
- | 从第一个操作数中减去第二个操作数 | A - B 给出 -10 |
* | 将两个操作数相乘 | A * B 给出 200 |
/ | 将分子除以分母。 | B / A 给出 2 |
% | 模运算符;给出整数除法后的余数。 | B % A 给出 0 |
++ | 增量运算符。它将整数值加一。 | A++ 给出 11 |
-- | 自减运算符。它将整数值减一。 | A-- 给出 9 |
例子
尝试以下示例来了解 Go 编程语言中可用的所有算术运算符 -
package main import "fmt" func main() { var a int = 21 var b int = 10 var c int c = a + b fmt.Printf("Line 1 - Value of c is %d\n", c ) c = a - b fmt.Printf("Line 2 - Value of c is %d\n", c ) c = a * b fmt.Printf("Line 3 - Value of c is %d\n", c ) c = a / b fmt.Printf("Line 4 - Value of c is %d\n", c ) c = a % b fmt.Printf("Line 5 - Value of c is %d\n", c ) a++ fmt.Printf("Line 6 - Value of a is %d\n", a ) a-- fmt.Printf("Line 7 - Value of a is %d\n", a ) }
当您编译并执行上述程序时,它会产生以下结果 -
Line 1 - Value of c is 31 Line 2 - Value of c is 11 Line 3 - Value of c is 210 Line 4 - Value of c is 2 Line 5 - Value of c is 1 Line 6 - Value of a is 22 Line 7 - Value of a is 21
