帮我看看怎么读取文件中的内容
学号| 名字| 语文| 数学| 英语
1| yusumao|22.00|33.00|44.00
2| yusumao|22.00|33.00|44.00
3| yusumao|22.00|33.00|44.00
4| yusumao|22.00|33.00|44.00
我想读取这个文件里面的学号和名字和语文和数学和英语。帮我看看怎么读取，如果可以的话，写一个程序来读取，我就把分全部给他
[解决办法]
//ls的是MFC的
//下面没写全，没调试，仅示意
#include <stdio.h>
typedef struct score
{
char *stuNum;
char *name;
float chinese;
float math;
float english;
}S,*pS;
int main()
{
FILE *fp;
char ch;
char chinese[5],math[5],english[5];
pS info=(pS)malloc(sizeof(S));
if(info=NULL)exit(0);
info-> stuNum= " ";
info-> name= " ";
info-> chinese=0.0;
info-> math=0.0;
info-> english=0.0;
if((fp=fopen( "d:\\score.txt ", "r+ "))==NULL)exit(0);
ch=fgetc(fp)
//while(ch!=EOF){
do//readline
{
*(info-> stuNum)++=ch;
if(ch== '| '){
*(info-> stuNum)++=ch;
if(ch== '| '){
*chinese++=ch;
if(ch== '| '){
*math++=ch;
if(ch== '| '){
*english++=ch;
}
}
}
}
if(ch= '\n ')break;
ch=fgetc(fp);
}while(1);
//}//没有对数据进行转换处理
//printf( "学号|名字| 语文| 数学| 英语 ");
printf( "%s|%s|%s|%s|%s\n ",info-> stuNum,info-> stuNum,chinese,math,english);
getch();
return 0;
}

#include <stdio.h>

int num=0;

float a=0,b=0,c=0;

if(!file)return 0;
while(!feof(file))
{
fscanf(file, "%d|%[^|]|%f|%f|%f\n ",&num,name,&a,&b,&c);
printf( "%d,%s,%f,%f,%f\n ",num,name,a,b,c);
}

看看我的，说明：
1.使用了单向链表，如果你要想操作更方便，可改成双向链表
2.使用了状态机，用于parser文件格式
3.测试用的文件最后一行是\n
4.纯CRT实现，VC6.0测试
