下表显示了D语言支持的所有算术运算符。假设变量A保持10，变量B保持20然后 -

操作者	描述	例
+	它增加了两个操作数。	A + B给出30
-	它从第一个操作数中减去第二个操作数。	A - B给-10
*	它将两个操作数相乘。	A * B给出200
/	它将分子除以分子。	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增加1。	A ++给出11
--	递减运算符将整数值减1。	A-- gives 9

例子 (Example)

尝试以下示例来理解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; 
}

编译并执行上述程序时，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
