下列是D语言支持赋值操作符:

运算符 描述 示例
= 简单赋值运算符,分配从右侧操作数的值,以左侧操作数 C = A + B will assign value of A + B into C
+= 添加和赋值操作符,它增加了右操作数为左操作数和结果分配给左操作数 C += A is equivalent to C = C + A
-= 减和赋值操作符,它减去右边的操作数从左边的操作数,并将结果赋值给左操作数 C -= A is equivalent to C = C - A
*= 乘法和赋值操作符,它乘以右边的操作数与左操作数和结果分配给左操作数 C *= A is equivalent to C = C * A
/= 除法和赋值操作符,它分为左操作数与右边的操作数,并将结果赋值给左操作数 C /= A is equivalent to C = C / A
%= 模量和赋值操作符,它采用模使用两个操作数和结果分配给左操作数 C %= A is equivalent to C = C % A
<<= 左移位并赋值运算符 C <<= 2 is same as C = C << 2
>>= 向右移位并赋值运算符 C >>= 2 is same as C = C >> 2
&= 按位AND赋值运算符 C &= 2 is same as C = C & 2
^= 按位异或和赋值运算符 C ^= 2 is same as C = C ^ 2
|= OR运算和赋值运算符 C |= 2 is same as C = C | 2

示例

试试下面的例子就明白了提供D编程语言的所有赋值运算符:

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;
}

当编译并执行上面的程序它会产生以下结果:

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
