The bitset operations (Table 17.3 (overleaf)) define various ways to test or set one or more bits. The bitset class also supports the bitwise operators that we covered in § 4.8 (p. 152). The operators have the same meaning when applied to bitset objects as the built-in operators have when applied to unsigned operands.

Table 17.3. bitset Operations

Several operations—count, size, all, any, and none—take no arguments and return information about the state of the entire bitset. Others—set, reset, and flip—change the state of the bitset. The members that change the bitset are overloaded. In each case, the version that ...
