Daily bit(e) of C++ #458, Formatting and extracting values to and from a std::string using std::stringstream.
If you need to format values into a std::string or extract formatted values from a std::string and are stuck in the pre-C++20 world, your main option is std::stringstream.
std::istringstream can be filled with a string and treated as any other istream object.
std::ostringstream can be treated as an ostream object with the option to extract the current content as std::string.
