一个整人加被人整的程序（求你心里想的数字）

#include <stdio.h>
int main(void)

   int head=0,count=-1,tail=100,cashe;
   char dec;

   while(1)
   {
      printf("Plase input the number you want to(0<=count<100):");
      scanf("%d",&count);
      while(getchar()!='\n');
      if(count<0||count>=100)
         printf("You input is error!\n");
      else
         break;
   }        
   while(1)
   {
      cashe=((head+tail)/2);
      if(tail-1==head)
            break;

         dec=getchar();
