下表列出了所有D语言支持的算术运算符。假设变量A=10和变量B=20，则：
| 运算符 | 描述 | 实例 |
|---|---|---|
| + | 增加了两个操作数 | A + B = 30 |
| - | 从第一中减去第二个操作数 | A - B = -10 |
| * | 两个操作数相乘 | A * B = 200 |
| / | 通过取消分子分裂分子 | B / A = 2 |
| % | 模运算符和其余整数除法 | B % A = 0 |
| ++ | 递增运算符相加整数值1 | A++ = 11 |
| -- | 递减运算符通过减少整数值1 | A-- = 9 |
试试下面的例子就明白了所有的D编程语言的算术运算符：
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 %dn", c );
c = a - b;
writefln("Line 2 - Value of c is %dn", c );
c = a * b;
writefln("Line 3 - Value of c is %dn", c );
c = a / b;
writefln("Line 4 - Value of c is %dn", c );
c = a % b;
writefln("Line 5 - Value of c is %dn", c );
c = a++;
writefln("Line 6 - Value of c is %dn", c );
c = a--;
writefln("Line 7 - Value of c is %dn", c );
char[] buf;
stdin.readln(buf);
return 0;
}
当编译并执行上面的程序，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
