结构体运用
结构体如下: typedef struct Room_Infor_info
{
char flour_num;
int room_num;
int area;
int contain_people;
int reside_people;
struct Room_Infor_info * next;
}Room_Infor;
extern Room_Infor *head;
我将结构体放在了jiegouti.h中,在编程的时候想通过不同的.c文件调用结构体中的结构体型的指针变量*head ,但是编译的时候有问题说error LNK2001: unresolved external symbol _head,我怀疑跟这个head有关系,大神请指教,跪求!!
