谁有空可以帮我看看的T^T

看看

int get_i_num(struct student *p,int n);
int get_i_name(struct student *p,int n);
int get_i_tel(struct student *p,int n);
改成
int get_i_num(struct student *p,int n,char *num);
int get_i_name(struct student *p,int n,char *name);
int get_i_tel(struct student *p,int n,char *tel);
函数参数定义不一致


void swap(struct student *p1,struct student *p2)
改成
void swap(struct student *p1,struct student *p2);
缺少；符号
case 10:
              save(stu,n);
              break;
改成
case 10:
              save_file(stu,n);
              break;
定义中无save函数
大功告成
