Hi, Ive gota complete a number of codes , i have the following one to complete , The organiser of a car rally requires a program(s) that will allow him to enter the competitor details, Name, Car (Make and Model), Engine size and Registration number. The program should store this information in a file. The rally is divided into five stages at the end of each stage the time for each competitor is recorded for that stage, this data should also be stored in a file. At the end of the rally when all the stages have been completed, a table should be produced that shows the aggregate time for each of the competitors. Example data: Name Make Model Engine Size Registration No. Ray Andrews Ford Escort MkII 1600 HGY 273M John Hill Opel Manta 2000 TBD 498F Andrew Smith Austin Mini Cooper 1300 DVT 749G The event normally attracts between 15 and 25 competitors. Stage times can be entered against the Car Registration number: Registration No. Stage Time Mins Secs HGY 273M 14 45 TBD 498F 15 56 DVT 749G 16 04 [Hint: It may be easier to store the time in seconds instead of minutes and seconds, then use this to perform the calculations, before doing the final output in Minutes and Seconds] The final Result will look as follows: Name Stage 1 Stage 2 Stage 3 Stage 4 Stage 5 Total Ray Andrews 14.33 23.43 12.12 34.56 etc John Hill etc etc Andrew Smith etc The organiser would also like the winner (the driver with the lowest time) to be identified automatically by the computer system. THATS THE QUERY, SO FAR I HAVE PUT SOME CODING TOGETHER BUT AM STUCK NOW , IS THEIR ANYONE WHO COULD DO THE LAST LITTLE BITS AND FINISH IT OFF OR GIVE SOME POINTERS PLEASE Code: #include <stdio.h> #include <stdlib.h> #include <string.h> #include <conio.h> #define MAX 25 /* Maximum number Rally Competitors*/ FILE *fp;

This is your assignment, not ours. I doubt that a person that can't be bothered to check the "Before you make a query" thread can be expected to complete an assignment which they have put off ad infinitum, because of their busy schedule conducting panty raids. You are certainly wecome to try. Post your attempts, if you get around to them, and we'll try to explain any errors, presuming that you can be bothered to delineate them intelligently.
