Question

c语言求助 帮我看看，求大神，错误是syntax error before'&' token,急

void read_files()
{
FILE *fp;
int i;
int j;
char adr[1000];
printf("请输入读取的文件地址:\n\n地址输入格式:例如d:\\\\Student.txt");
scanf("%s",adr);
printf("读取中\n");
if(fp=fopen(adr,"r"))
{
fscanf(fp,"%d",&student_count);
for(i=0;i<student_count;i++)
{
fscanf(fp,"%ld%s%d",&s[i].num.&s[i].name,&s[i].lesson_count);
for(j=0;j<s[i].lesson_count;j++)
{
fscanf(fp,"%ld%s%d%f",&s[i].l[j].lesson_num,&s[i].l[j].lesson_name,
&s[i].l[j].lesson_score,&s[i].l[j].lesson_num1);
}
}
printf("读取成功\n");
fclose(fp);
}
else
{
printf("读取失败\n");
}
}
为何我重新打了一遍就正确了

Answer 1

fscanf(fp,"%ld%s%d",&s[i].num.&s[i].name,&s[i].lesson_count);
改为：fscanf(fp,"%ld%s%d",&s[i].num,&s[i].name,&s[i].lesson_count);
主要是符号写错了：&s[i].name前面的“.”需要改为","

Answer 2

for循环中
fscanf(fp,"%ld%s%d",&s[i].num.&s[i].name,&s[i].lesson_count);这里错了， 改为
fscanf(fp,"%ld%s%d",&s[i].num,s[i].name,&s[i].lesson_count);

追答

应该是第一次打的时候手误了，第二次打的时候没手误了

Answer 3

fscanf(fp,"%d",&student_count);有错误
