犯病前：

犯病后：

源码：

 1 #include<stdio.h>
 2 main(){
 3     // printf("欢迎使用电子通讯录\n");
 4     FILE*fp=fopen("naph.txt","r");
 5     char buf[11];
 6     int i,j,k,n,n2=0,n3=0,i2;
 7     while(fgets(buf,1024,fp)){n++;}
 8     // printf("%d\n",n);
 9     char name[n][100],numb[n][100];
10     rewind(fp);
11     while(fgets(buf,1024,fp)){
12         for(i=0;buf[i]!=13;i++){
13             if(buf[i]==58)
14                 break;
15             printf(" %d:%c",buf[i],buf[i]);         
16             // name[n2][i]=buf[i];  
17         }
18         k=i;
19         printf("\n");
20         name[n2][i++]=0;
21         for(j=0;j<11;i++,j++){
22             printf(" %d:%c",buf[i],buf[i]);
23             // printf("%d ",i-10);
24             // numb[n2][j]=buf[i];        
25         }
26         // numb[n2][j]=0;
27         // printf("%s\n",name[n2]);
