char my_tolower(char ch) { return static_cast<char>(std::tolower(static_cast<unsigned char>(ch))); }类似地,迭代器的值类型为 char 或signed char 时,不应直接将它们用于标准算法。而是要首先转换值为 unsigned char: std::string str_tolower(std::string s) { std::transform(s.begin(), s...

The container manages the storage space that is allocated for its elements and provides member functions to access them, either directly or through iterators (objects with properties similar to pointers). Most containers have at least several member functions in common, and share functionalities. Whi...
