D 语言 - 算术运算符
下表列出了D语言支持的所有算术运算符。 假设变量 A 为 10，变量 B 为 20 −
| 运算符 | 描述 | 示例 |
|---|---|---|
| + | 它添加两个操作数。 | A + B 为 30 |
| - | 它从第一个操作数中减去第二个操作数。 | A - B 给出 -10 |
| * | 它将两个操作数相乘。 | A * B 给出 200 |
| / | 它将分子除以分母。 | B / A 给出 2 |
| % | 它返回整数除法的余数。 | B % A 给出 0 |
| ++ | 增量运算符将整数值加一。 | A++ 给出 11 |
| -- | 递减运算符将整数值减一。 | A-- 给出 9 |
示例
尝试以下示例来了解 D 编程语言中可用的所有算术运算符 −
import std.stdio;
int main(string[] args) {
int a = 21;
int b = 10;
int c ;
c = a + b;
writefln("Line 1 - Value of c is %d\n", c );
c = a - b;
writefln("Line 2 - Value of c is %d\n", c );
c = a * b;
writefln("Line 3 - Value of c is %d\n", c );
c = a / b;
writefln("Line 4 - Value of c is %d\n", c );
c = a % b;
writefln("Line 5 - Value of c is %d\n", c );
c = a++;
writefln("Line 6 - Value of c is %d\n", c );
c = a--;
writefln("Line 7 - Value of c is %d\n", c );
char[] buf;
stdin.readln(buf);
return 0;
}
当你编译并执行上面的程序时，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 c is 21 Line 7 - Value of c is 22
