Bitset class c++

WebConstructs a basic_string object that represents the bits in the bitset as a succession of zeros and/or ones. The string returned by this function has the same representation as the output produced by inserting the bitset directly into an output stream with operator<<. Notice that this function template uses the template parameters to define the return type. WebReturns the number of bits in the bitset. This is the template parameter with which the bitset class is instantiated (template parameter N). Parameters none Return Value The number of bits in the bitset. size_t is an unsigned integral type.
