一个关于C的fprintfΣfscanf函数问题，新手不知道哪里错了。请大神指点。

小小平蛋

#include <stdio.h>
#include <conio.h>
#include <stdlib.h>
struct address{
char name[20];
int age;
char cla[30];
char tele[20];
};
void save(address t[],int n){
int i;
FILE *fp;
if((fp=fopen("c:\\vc\4-8.txt","wb"))==NULL){
  printf("can not open this file");
  exit(1);
}
printf("\nSaving file\n");
fprintf(fp,"%d",n);
fprintf(fp,"\r\n");
for(i=0;i<n;i++){
  fprintf(fp,"%-20s%-30d%-30s%10s",t[i].name,t[i].age,t[i].cla,t[i].tele);
  fprintf(fp,"\r\n");}
  fclose(fp);
  printf("****保存成功****");
}
int load(address t[]){
  int i,n;
  FILE *fp;
   if((fp=fopen("c:\\vc\4-8.txt","wb"))==NULL){

改动的地方比较多，我应该是都做了注释标记
