D語言的支持還有其他一些重要的運算符，包括的sizeof和？ ：。

運算符	描述	示例
sizeof	返回一個變量的大小。	a.sizeof, 其中a是整數，將返回4。
&	返回一個變量的地址。	&a; 將得到的變量actaul地址。
*	指向變量的指針。	*a; 指針變量。
? :	條件表達式	If Condition is true ? Then value X : Otherwise value Y

示例

試試下麵的例子就明白了所有的D編程語言雜運算符：

import std.stdio;

int main(string[] args)
{
   int a = 4;
   short b;
   double c;
   int* ptr;

   /* example of sizeof operator */
   writefln("Line 1 - Size of variable a = %d
", a.sizeof );
   writefln("Line 2 - Size of variable b = %d
", b.sizeof );
   writefln("Line 3 - Size of variable c= %d
", c.sizeof );

   /* example of & and * operators */
   ptr = &a;	/* 'ptr' now contains the address of 'a'*/
   writefln("value of a is  %d
", a);
   writefln("*ptr is %d.
", *ptr);

   /* example of ternary operator */
   a = 10;
   b = (a == 1) ? 20: 30;
   writefln( "Value of b is %d
", b );

   b = (a == 10) ? 20: 30;
   writefln( "Value of b is %d
", b );
   return 0;
}

當編譯並執行上麵的程序它會產生以下結果：

value of a is  4
*ptr is 4.
Value of b is 30
Value of b is 20
