C++ In a Nutshell

Name

bitor operator — Bitwise inclusive or operator

Synopsis

               inclusive-or-expr := inclusive-or-expr "|" exclusive-or-expr | 
    inclusive-or-expr bitor exclusive-or-expr
            

The bitwise or operator requires integer or enumeration operands. It performs the usual arithmetic conversions, then does an inclusive or operation on pairs of bits in the operands, resulting in an integer. The bitor operator is interchangeable with the | token.

Example

unsigned bitmask = 0xF0F0;
bitmask = bitmask| 0x0102; // bitmask becomes 0xF1F2.
