c语言复合赋值运算符

Compound-assignment operators provide a shorter syntax for assigning the result of an arithmetic or [bitwise][] operator. They perform the operation on the two operands before assigning the result to the first operand.

复合分配运算符为分配算术[运算][bitwise]符或[按位运算][bitwise]符的结果提供了较短的语法。 在将结果分配给第一个操作数之前，它们先对两个操作数执行运算。

## Java中的复合赋值运算符 **(** Compound-Assignment Operators in Java **)** ##

[Java][] supports 11 compound-assignment operators:

[Java][]支持11种复合赋值运算符：

+=   assigns the result of the addition.
     -=   assigns the result of the subtraction.
     *=   assigns the result of the multiplication
     /=   assigns the result of the division.
     %=   assigns the remainder of the division.
     &=   assigns the result of the logical AND.
     |=   assigns the result of the logical OR.
     ^=   assigns the result of the logical XOR.
     <<=  assigns the result of the signed left bit shift.
     >>=  assigns the result of the signed right bit shift.
     >>>= assigns the result of the unsigned right bit shift.

## 用法示例 **(** Example Usage **)** ##

To assign the result of an addition operation to a variable using the standard syntax:

使用标准语法将加法运算的结果分配给变量：

//add 2 to the value of number
     number = number + 2;

But use a compound-assignment operator to effect the same outcome with the simpler syntax:

但是，使用复合赋值运算符以更简单的语法实现相同的结果：

//add 2 to the value of number
     number += 2;
