It consists of three main modules: the instruction of self-definition function used in the process of initialization of screen and menu system, the instruction of ini- tialization screen and menu system, and the instruction of self-definition function used in keyboard service program. The study reveals the properties of abundance and practice of the library function of C language.展开更多
