assignment-expr := logical-or-expr ^= assignment-expr | 
    logical-or-expr xor_eq assignment-expr

The xor_eq operator is an assignment operator that performs bitwise exclusive or. It is equivalent to logical-or-expr = logical-or-expr ^ assignment-expr, except that logical-or-expr is evaluated only once.

The keyword xor_eq is interchangeable with the ^= token.

Example

unsigned bitmask = 0xFFF0;
bitmask ^= 0x0F12;  // bitmask becomes 0xF0E2.
