编程时遇到一个问题。一天了也没有解决。能帮助的感激不尽
我是要解决一个不定数目的数据处理问题。在解决数据输入时没有问题，在把输入的数据写入文件时也没有问题，就是在把文件链接成一个链表后，我想看一些链接是否成功，就调用了一下链接后链表，想输出开始输入的数据，就出了问题了。这是我的程序：其中有很多输出“right"的语句是用来调试哪一步出错的。求高人指点一下。我这都快被整得崩溃了。#include<stdio.h>
#include<stdlib.h>

} 链接用的函数结束
main() 主函数
{
void input();
int x;
struct employees2 *load();
struct employees2 *pp;
input(); 调用输入函数
printf("right5");
pp=load(); 调用链接函数，大致就是这里出现了问题
printf("right6");
x=pp->phone; 没法执行这一步。一旦执行就显示可执行文件一停止工作
printf("right7");
printf("%d",x);
system("pause");
}
