我实在的调不出来了，求帮忙！！！
一个关于学生成绩管理系统的代码，编译后总提示void exit(struct student *manage,int n);这一行有second formal parameter list longer than the first list的警告，还有.c(140) : error C2198: 'exit' : too few actual parameters的错误，最后就是删除学生信息的那一段代码求完善，我编不了，谢谢各位了，代码如下：#include<stdio.h>
#include<stdlib.h>
#include<string.h>
#include<malloc.h>
#include<conio.h>
