Can someone please help me get my code running! I am trying to do a sectional sort based on mileage. I have got a lot of code wrote based on the book, but I can not get it to work or figure it out! Please assist!

Then IMO you need to start over. Write a little bit, get it working. Then write a little more, get it working. Write a little more....
Trying to debug 260 lines with no idea where the errors could be is very difficult.

Well let me post what I have working:

   bool found = false;    // Flag to indicate if the value was found 

   while (index < size && !found)
   {
      if (object[index].getVIN() == value) // If the value is found
      {
         found = true;          // Set the flag 
         position = index;      // Record the value's subscript 
      }
      index++;                  // Go to the next element 
   }
   return position;             // Return the position

If you run this with the class file it will do my linear searches and print out the information! Now I just need to add a sectional sort to that! If you or someone could help me!

Hey guys I appreciate the help and you taking time to look at this for me! I am trying to work on some programs in the back of the book(this is one) to help me study for my test later this week! So it would b great to be able to get this selection sort down pat. And once I get this sort done I plan to do a binary search with it! So please assist me guys!!
