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

参考技术A 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"," 参考技术B 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

参考技术C fscanf(fp,"%d",&student_count);有错误

大神们帮我看看程序吧，linux C语言编程 隐式声明和strlen出错，改为sizeof后，段错误，

/*ex8-2server.c*/

int listenfd, connfd;

listenfd=socket(AF_INET, SOCK_STREAM,0);
if(listenfd<0)

printf("Socket created failed.\n");
return -1;

return -1;

这是客户机 服务器连接程序，通过套接字建立连接，客户机使用流套接字向服务器请求日期和时间，服务器在收到请求后，回答请求并显示出客户的地址，但是在终端运行后，服务器提示listening，，，，并提示段错误，客户端只提示connecting.........无法正常运行

段错误说明非法内存操作 参考技术A sizeof会计算结束符 参考技术B 你能把你的问题说出来不 这么多 怎么看？？？
