scanf("%c",an);//为什么这名不起作用
}while(an == 'y');
ave = sum / num;
printf("%d members' average age is %d\n",num,ave);

#include <stdio.h> 



void main() 

{ 

  char an = 'y'; 

  int ave = 0, sum = 0, num = 0; 

  int age; 

  do { 

      printf("Enter the number:\n"); 

      scanf("%d",&age,++num); 

      fflush(stdin);//第一输入完 要清空下 缓冲区

	  sum += age; 

      printf("Do you wish to enter another num?\n"); 

      scanf("%c",&an);

      }while(an == 'y'); 

  ave = sum / num; 

  printf("%d members' average age is %d\n",num,ave); 



}
