WebThe dynamic_bitsetclass represents a set of bits. provides accesses to the value of individual bits via an operator[]and provides all of the bitwise operators that one can apply to builtin integers, such as operator&and operator<<. The number of bits in the set is specified at runtime via a parameter to the constructor of the dynamic_bitset. WebBitset class emulates space efficient array of boolean values, where each element occupies only one bit. As it emulates array, its index also starts from 0th position. Individual bit from bitset can be accessed using subscript operator. For instance to access first element of bitset foo use foo [0].
