What does ‖ mean in C language?

The | symbol in C language represents the bitwise OR operator, which performs a logical OR operation on the corresponding bits of two binary numbers. If one of the corresponding bits is 1, the result is 1, otherwise it is 0. It is commonly used to set binary bits, combine bit masks, and check whether a bit is 1.

In C language | operator

In C language, \| symbol represents Bitwise OR operator. It is used to logically OR the corresponding bits of two binary numbers, and the result of each bit after calculation is:

• If both bits are 1, the result is 1.
• If either of the two bits is 1, the result is 1.
• If both bits are 0, the result is 0.

Example:

Suppose there are the following two 8-bit binary numbers:

<code>10101010
01010101</code>

Perform a bitwise OR on these two numbers After the operation, we get:

<code>11111111</code>

This is because:

• The highest bit of 10101010 (1) and the highest bit of 01010101 (0) perform an OR operation, and the result is 1.
• And so on, each bit is ORed, and the final result is 11111111.

Uses:

The bitwise OR operator is usually used to:

• Set a specific value of a binary bit.
• Combine two bitmasks.
• Check if the bit is 1.
