结构体 文件问题在主函数中调用read()为什么每次都显示cannot open file

Question

//定义结构体//
struct achievement
{int number;
char name[20];
char sex;
float achievement1,achievement2,achievement3;
}tab_achievement[N];

//读出文件函数//
void read()

{FILE *fp;
int i,n;
if((fp=fopen("C:\Users\Administrator\Desktop\ab.txt","r+"))==NULL) //如果不能打开文件
{printf("cannot open file\n");
exit(0); //使程序终止
}

for(i=0;i<n;i++)
{fscanf(fp,"%d%s%s%f%f%f",tab_achievement[i].number,tab_achievement[i].name,tab_achievement[i].sex,tab_achievement[i].achievement1,tab_achievement[i].achievement2,tab_achievement[i].achievement3);
}
fclose(fp); //关闭文件
}

ab.txt中的数据
55140701 wangyiyi n 88 99 99
55140702 wangyier n 85 97 92
55140703 wangyisa w 83 91 78
55140704 wangyisi n 77 98 89
55140705 wangyiwu n 99 67 88

Answer 1

 C:\\Users\\Administrator\\Desktop\\ab.txt

路径问题，这样试试
