程序代码：

#include<stdio.h>
#include<stdlib.h>
void main()
{
    FILE *fp;int i,a[5];char filename[20];
    scanf("%s",filename);
    fp=fopen(filename,"r+");
    //fp=fopen("E:\\1.txt","r+");
    if(fp==NULL)
    {printf("can't found the file\n");exit(0);}
    for(i=0;i<5;i++)
    {
        fread(a+i,sizeof(int),1,fp);
        printf("  a[i]=%d  ",a[i]);
    }
    fclose(fp);
}
