This paper shares the specific code of C language song information management system for your reference, the specific content is as follows
System function: the system works by menu, song information includes: song name, singer, lyricist, composition, album, publication date, publishing company. Try to design 1 hall song management system, so that it can provide the following functions: song information input, modify, insert, delete functions; Song sorting browse function; Query by song name, query by singer and other functions.
The complete implementation code is as follows:
#include "stdio.h"
#include "stdlib.h"
#include "string.h"
// Song information includes: song title, singer, lyrics, composition, album, publication date, publishing company
typedef struct music
