What does =& mean in c++

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:

• x is the left operand, which is a A variable or expression that will store the result of the operation.
• y is the right operand, a constant, variable, or expression that provides the bit pattern to be performed bitwise with x.

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:

##xyx &= y101111011001##Function:

# The ##&= operator is typically used for the following purposes:

Set a flag bit to 1 or 0

Clear a specific flag bit
• Check a specific bit pattern The state of bits
• Perform a bit mask operation (set certain bits to a specific value)
• Avoid confusion:

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.
