In C, the &= operator is a bitwise AND operator, used to perform a bitwise AND operation on two bit patterns, setting the corresponding bits 1 and 1 in the two bit patterns to 1 , otherwise set to 0.
&= operator in C
In C, the &= operator is a bitwise AND Operator that performs a bitwise AND operation on two bit patterns (binary numbers).
Definition:
x &= y;
Where:
Operation:
&= operator compares corresponding bits in two bit patterns from left to right. If both bits are 1, the result bit is 1; otherwise, the result bit is 0.
For example:
y | x &= y | |
---|---|---|
1101 | 1001 |
# The ##&= operator is typically used for the following purposes:
Set a flag bit to 1 or 0
Important Just remember that the &= operator is different from the assignment operator =. The assignment operator assigns the value of the right operand directly to the left operand, while the &= operator modifies the value of the left operand rather than assigning it directly.
