What does | mean in c language?

In C language, the vertical bar symbol (|) represents the bitwise operator, also known as the bitwise OR operator, which is used to perform a bitwise logical OR operation and convert at least one of the two binary bits into The result of 1 is set to 1, otherwise it is set to 0.

The meaning of | in C language

In C language, the vertical bar symbol (|) represents a bit operator, also known as the bitwise OR operator.

Bitwise OR operation

When the | operator is used on two binary numbers, it performs a logical OR operation on each corresponding bit.

Logical OR operation

• If both bits are 0, the result is 0.
• If at least one of the two bits is 1, the result is 1.

Syntax

result = x | y;

Where, x and y are binary numbers or bit sequences.

Example

Suppose we have two 8-bit binary numbers:

<code>x = 01101100
y = 10110111</code>

The result of the bitwise OR operation is as follows:

<code>x | y = 11111111</code>

Application

Bitwise OR operations are typically used for the following purposes:

• Set or clear bits
• Combining flags
• Mask operation
• Data compression
