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.
