下列是D語言支持賦值操作符：

運算符	描述	示例
=	簡單賦值運算符，分配從右側操作數的值，以左側操作數	C = A + B will assign value of A + B into C
+=	添加和賦值操作符，它增加了右操作數為左操作數和結果分配給左操作數	C += A is equivalent to C = C + A
-=	減和賦值操作符，它減去右邊的操作數從左邊的操作數，並將結果賦值給左操作數	C -= A is equivalent to C = C - A
*=	乘法和賦值操作符，它乘以右邊的操作數與左操作數和結果分配給左操作數	C *= A is equivalent to C = C * A
/=	除法和賦值操作符，它分為左操作數與右邊的操作數，並將結果賦值給左操作數	C /= A is equivalent to C = C / A
%=	模量和賦值操作符，它采用模使用兩個操作數和結果分配給左操作數	C %= A is equivalent to C = C % A
<<=	左移位並賦值運算符	C <<= 2 is same as C = C << 2
>>=	向右移位並賦值運算符	C >>= 2 is same as C = C >> 2
&=	按位AND賦值運算符	C &= 2 is same as C = C & 2
^=	按位異或和賦值運算符	C ^= 2 is same as C = C ^ 2
|=	OR運算和賦值運算符	C |= 2 is same as C = C | 2

示例

試試下麵的例子就明白了提供D編程語言的所有賦值運算符：

import std.stdio;

int main(string[] args)
{
   int a = 21;
   int c ;

   c =  a;
   writefln("Line 1 - =  Operator Example, Value of c = %d
", c );

   c +=  a;
   writefln("Line 2 - += Operator Example, Value of c = %d
", c );

   c -=  a;
   writefln("Line 3 - -= Operator Example, Value of c = %d
", c );

   c *=  a;
   writefln("Line 4 - *= Operator Example, Value of c = %d
", c );

   c /=  a;
   writefln("Line 5 - /= Operator Example, Value of c = %d
", c );

   c  = 200;
   c = c % a;
   writefln("Line 6 - %s= Operator Example, Value of c = %d
",'x25', c );

   c <<=  2;
   writefln("Line 7 - <<= Operator Example, Value of c = %d
", c );

   c >>=  2;
   writefln("Line 8 - >>= Operator Example, Value of c = %d
", c );

   c &=  2;
   writefln("Line 9 - &= Operator Example, Value of c = %d
", c );

   c ^=  2;
   writefln("Line 10 - ^= Operator Example, Value of c = %d
", c );

   c |=  2;
   writefln("Line 11 - |= Operator Example, Value of c = %d
", c );
   return 0;
}

當編譯並執行上麵的程序它會產生以下結果：

Line 1 - =  Operator Example, Value of c = 21

Line 2 - += Operator Example, Value of c = 42

Line 3 - -= Operator Example, Value of c = 21

Line 4 - *= Operator Example, Value of c = 441

Line 5 - /= Operator Example, Value of c = 21

Line 6 - %= Operator Example, Value of c = 11

Line 7 - <<= Operator Example, Value of c = 44

Line 8 - >>= Operator Example, Value of c = 11

Line 9 - &= Operator Example, Value of c = 2

Line 10 - ^= Operator Example, Value of c = 0

Line 11 - |= Operator Example, Value of c = 2
