Question

读取号码到数组只能读出一组，比较后怎么返回重新比较？

代码如下：#include<stdio.h>
#include<sys/types.h>
#include<sys/ipc.h>
#include<sys/shm.h>
#include<string.h>
#define SHMKEY 75

#define CLIENTTWO 150
#define CLIENTTHREE 200

}  
int choice,i;  
char ch[100],c; 
 fgets(ch,12,fp);
        display(); 
        do 
       {   
        printf("Please choice a feature :\n"); 
        scanf("%d",&choice);
