The "bitset" class provides a convenient way to work with binary data and can be used to convert a binary string to an integer. Conclusion: Converting a binary string to an integer in C++ is a relatively simple task.
WebBitsets have the feature of being able to be constructed from and converted to both integer values and binary strings (see its constructor and members to_ulong and to_string ). They …
