WebJul 24, 2024 · std::bitset Converts the contents of the bitset to an unsigned long integer. The first bit of the bitset corresponds to the least significant digit of the number and the last bit corresponds to the most significant digit. Parameters (none) Return value the converted integer Exceptions Webthe number of bits in the bitset, must be an integer constant. Second, bitsetis not a Sequence; in fact, it is not an STL Containerat all. It does not have iterators, for example, or begin()and end()member functions. Instead, bitset's interface resembles that of unsigned integers. It defines bitwise arithmetic operators such as &=, =, and ^=.
