编程题：文件读写fprintf（）、fscanf（）使用，功能：将5个学生记录输入文件d：\stu1.txt中，并且显示在屏幕上。  

#include<stdio.h>

void main()

{

FILE *fp;long num;int n,score;char name[20]; int N=5;

fp=fopen("d:\\s tu1.txt","w");

for(n=1;n<=N;n++)

{ scanf("%s%10ld%d",name,&num,&score);

  fprintf(fp,"%20s%10ld%5d\n",name,num,score);

}

fclose(fp);

fp=fopen("d:\\stu1.txt","r");

for(n=1;n<=N;n++)

{fscanf(fp,"%20s%10ld%5d\n",name,&num,&score);

 printf("%20s%10ld%5d\n",name,num,score);

}

fclose(fp);

}
