Original: The class template basic_stringstream implements input/output operations on memory (std::basic_string) based streams. It essentially wraps a raw string device implementation (basic_stringbuf) into a higher-level interface (basic_iostream). The complete interface to unique basic_stringbuf m...

Path Match: If the complete match fails, the code attempts to match inputs like cpp26 to paths like cpp/26. For instance, if the user inputs cppstring, the code tries to find cpp/string. Partial Path Match: If the previous two matches fail, the code attempts a partial path match. ...
