result &= expression

Parameters

Result

Any variable .

Expression

Any expression .

Description

Using this operator is equivalent to using the following statement:

result = result & expression

The &= operator looks at the value of the binary notation of result and expression and performs a bitwise and action on it. The output of the operation is as follows:

0101    (result)1100    (expression)----0100    Output

At any given time, as long as two expressions are 1 on one, the result is 1. Otherwise, the bit of the result is 0.
