这是书上的程序，我怎么找不到，运行了，出现的问题是找不到
#include "stdio.h"
#define n 15
void main()
{
    int i,number,top,bott,mid,loca, a[n],flag=1,sign;
    char c;
    printf("shu ru shu zhi:\n");
     scanf("%d",&a[0]);
     i=1;
      while (i<n)
      {
         scanf("%d",&a[i]);
         if (a[i]>=a[i-1])
              i++;
          else printf("chong xin shu ru:\n");
      }
    printf("\n");
     for(i=0;i<n;i++)
         printf("%3d",a[i]);
     printf("\n");
     while (flag)
     {printf("yao zhao de shu zhi:" );
     scanf("%d",&number);
     sign=0;
     top=0;
     bott=n-1;
     if((number<a[0])||(number>a[n-1]))
      loca=-1;
     while ((!sign)&&(top>=bott))
     {  mid=(bott+top)/2;
     if(number==a[mid])
     {   loca=mid;
         printf("zhao dao le:%d shi zai di %d ge shu zhi.",number,loca+1);
         sign=1;
     }
     else if(number<a[mid])
         bott=mid-1;
     else top=mid+1;
     
     }
     if((!sign)||(loca==-1))
         printf("mei you zhao dao  %d \n",number);
     printf("shi fou ji xu zhao?y/n?");
      scanf(" %c",&c);
     if((c=='n')||(c=='N'))
         flag=0;
     
     
     }

}
运行结果就是找不到，请高手帮忙，谢谢了

建议用函数来搞这样看的我想找猫哥！

错误已经标明，如下：
#include "stdio.h"
 #define n 15
 void main()
 {
     int i,number,top,bott,mid,loca, a[n],flag=1,sign;
     char c;
     printf("shu ru shu zhi:\n");
      scanf("%d",&a[0]);
      i=1;
       while (i<n)
       {
          scanf("%d",&a[i]);
          if (a[i]>=a[i-1])
               i++;
           else printf("chong xin shu ru:\n");
       }
     printf("\n");
      for(i=0;i<n;i++)
          printf("%3d",a[i]);
      printf("\n");
      while (flag)
      {printf("yao zhao de shu zhi:" );
      scanf("%d",&number);
      sign=0;
      top=0;       /*这错了，该是top=n-1 */
      bott=n-1;     /*这也错了，该是bott=0 */
      if((number<a[0])||(number>a[n-1]))
       loca=-1;
      while ((!sign)&&(top>=bott))
      {  mid=(bott+top)/2;
      if(number==a[mid])
      {   loca=mid;
          printf("zhao dao le:%d shi zai di %d ge shu zhi.",number,loca+1);
          sign=1;
      }
      else if(number<a[mid])
          bott=mid-1;
      else top=mid+1;
      
      }
      if((!sign)||(loca==-1))
          printf("mei you zhao dao  %d \n",number);
      printf("shi fou ji xu zhao?y/n?");
       scanf(" %c",&c);
      if((c=='n')||(c=='N'))
          flag=0;
      
      
      }
 
}

改正后试试吧

谢谢您了，我试试看
