What is double vertical line in C language

The bitwise OR operator represents the vertical line symbol (|) in C language. It operates two operands bitwise, when either of the two bits is 1, the result bit is 1, otherwise it is 0.

‖The meaning of it in C language

‖In C language, it is a vertical line symbol, which represents a bitwise or (binary OR) operation.

Bitwise or (OR) operation

Bitwise or a bit-level operation that logically or operates on each binary bit in an operand. If either of the two bits is 1, the result bit is 1; otherwise, the result bit is 0.

grammar

The syntax for bitwise or operation is as follows:

 <code>x | y</code>

in:

• x and y are the two operands to perform bitwise or operation

Example

Assume x is 01110101 (117 in decimal) and y is 10101111 (183 in decimal). Their bitwise or operations are:

 <code>01110101 | 10101111 ---------- 11111111</code>

Therefore, the result is 11111111 (255 in decimal).
