mainfile.h

该程序实现了用文件记录变长字节流

struct element
{int key;
char name[8];
char rest[20];
int deletetag;
int next;
};
const int b1=sizeof(element);
struct team
{element data[20];
};
const int b2=sizeof(team);
struct indexnode
{int value;
int num;
int deletetag;};
const int b3=sizeof(indexnode);
void Insert(char *p1,char *p2,element &a);
bool maindelete(char *p1,char *p2,element a);
void mainprint(char *p1,char *p2);
element mainsearch(char *p1,char *p2,element &a);
