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)
Here is the password fileCode:#include <stdio.h> #include <stdlib.h> #include <string.h> #include <math.h> #include <time.h> //#include <malloc.h> /* function Declarations */ int FunctionPassword(FILE *Fpassword);

system ("pause"); exit(0); } Fplanes=fopen("/users/williammcfadden/Documents/school/EGR 115/Final Project/planes.txt", "w+"); /* used "w+' because i want to write over any previous information in that file */ /* and not add any more information to the file */ Fdistout=fopen("/users/williammcfadden/Documents/school/EGR 115/Final Project/distlog.out", "w");

OK here are some more problems, It creates the random numbers file and it looks like this:Code:leia 12345 darth 23456 r2d2 34567 solo 45678 jabba 56789 yoda 67890
But when it does calculations with the data file and prints to the distlog.out file it prints thisCode:1 38 27 7 24 23 38 12 15 23 14 9 27 18 8 11 9 29 3 24 40 34 44 2 34 45 27 46 3 25 19 45 47 26 25 37 41 26 28 2 16 44 3 49 31 26 25 42 33 14 8 1 5 11 19 47 36 4 4 7 21 25 5 34 19 14 29 14 1 46 45 21 42 26 2 26 23 35 5 47 46 33 3 12 21 38 9 35 38 16 45 41 44 38 7 32 13 1 8 3 34 34 37 43 19 17 31 19 31 37 25 38 36 8 49 49 29 18 44 42 13 12 29 49 16 47 36 18 28 37 26 8 32 29 49 4 42 21 31 21 7 44 42 28 14 14 13 22 21 24
Notice that none of these numbers are in the data file. Where did it get these 0's from?Code:WARNING!!! Aircraft at 0 0 0 is 0.00 KM away WARNING!!! Aircraft at 0 0 0 is 0.00 KM away WARNING!!!

and when I get to the function which prints to the screen it gives this
What can be the problem? I keep editing this thread when I edit the program and I keep making things worse.Code:[Session started at 2005-11-28 22:04:14 -0500.] Please enter your name darth Please enter your password 23456 Nearest aircraft at 0 0 0 is 00.00 KM away Final Project has exited with status 0.
