uj5u.com熱心網友回復：
int loadSql(data *sql,char path[100]);
void printAction();
void dealAction(int action);
int searchWord(char word[20]);
int searchCn(char cn[80]);
void saveSql();
請在程式的最前面加上函式說明，這樣編譯的警告錯誤就沒有了。
uj5u.com熱心網友回復：
int loadSql(data *, char []);
void printAction( void );
void dealAction(int);
int searchWord(char []);
int searchCn(char []);
void saveSql( void );
更一般的函式說明是這樣的。
