WebOct 23, 2024 · Notes. Because copying std::invalid_argument is not permitted to throw exceptions, this message is typically stored internally as a separately-allocated reference-counted string.

Constructor of std::bitset with string argument expects the string to contain only 0 s and 1 s. Probably your string contains values like a instead of 1100001. So if you want the 32 bits of 4 bytes of your input string to be put into a bitset, you have to convert the string to a sequence of 32 ones and zeros first. Web2) Copy constructor: If other contains a value, initializes the contained value as if direct-initializing (but not direct-list-initializing) an object of type T with the expression * other.If other does not contain a value, constructs an object that does not contain a value..

It doesn't do either. It does a memberwise copy. I.e. it copies all the members of the class using their copy constructors. If those members have copy constructors that do a deep copy then you'll get a deep copy, if they do a shallow copy then you'll get a shallow copy, or they could do something else entirely.
