I have finished my program, one problem
Hello guys and gals I have finally finished my program! Everything runs smoothly until the program gets to the last function. Instead of giving me the lowest value it gives me a value that is not even part of the planes data file. Can anyone see what the problem is? And thanks again for all your help.
anyway here is the program (in code tags)
Code:

But when it does calculations with the data file and prints to the distlog.out file it prints this

Notice that none of these numbers are in the data file. Where did it get these 0's from?
and when I get to the function which prints to the screen it gives this

Nearest aircraft at 0 0 0 is 00.00 KM away
Final Project has exited with status 0.
What can be the problem? I keep editing this thread when I edit the program and I keep making things worse.
