## vertical bar - Computer Definition

The vertical bar character (|), located over the backslash (\) key, is used as an OR operator. In the C/C++ language, two vertical bars are used; for example, **if (x == 'a' || x == 'b')** means "if X is equal to A or B." It is also used as a pipe symbol, which directs the output of one process to another. See filters and pipes.
