int beg,end,mid,target;
clrscr();
printf("enter the total numbers:&#8255;);
scanf("%d&#8255;,&n);
printf("enter the array elements:&#8255; );
for(i=0;i<n;i++)
scanf("%d&#8255;,&a[i]);
for(i=0;i<n-1;i++)
    {  
     for(j=0;j<n-i-1;j++)
       {
          If(a[j+1]<a[j])
            {
               temp=a[j];
                a[j]=a[j+1];
                 a[j+1]=temp;
            }
      }
  }
printf("the sorted numbers are:&#8255;);
for(i=0;i<n;i++)
printf("%4d&#8255;,a[i]);
beg=a[0];
end=a[9];
mid=(beg+end)/2;
printf("\nenter the number to be searched:&#8255;);
scanf("%d&#8255;,&target);
while(beg<=end && a[mid]!=target)
{
if(target<a[mid])
 end=mid-1;
else
beg=mid+1;
mid=(beg+end)/2;
}
If(a[mid]==target)
  {
printf("\nthe number is found at position %2d&#8255;,mid);
  }
else
    {
printf("\nthe number is not found:&#8255;);
     }
getch();
}


thanks
