Feb 17, 2023 · std::string class in C++. C++ has in its definition a way to represent a sequence of characters as an object of the class. This class is called std:: string. The string class stores the characters as a sequence of bytes with the functionality of allowing access to the single-byte character. This will have no effect for /std:c++14 and /std:c++17 users, and we can expect that, at least initially, the population of /std:c++20 users will be the most eager upgraders for whom rebuilding the world is the least onerous.
