Question

Write a program that reads four triathlon race time records from a file. The name of the file is racedat.txt. Each line of the file represents one record and contains an athlete identifier (a single character) and three numeric values. The three values are the completion times (in minutes) for the running, swimming, and biking stages of a triathlon. You will produce a nicely formatted report that displays these values, as well as the total time for each athlete. Finally, your report should calculate the average total time for the race.

Hint: You may create your own racedat.txt file using Windows Notepad or other text editor. Your input file should have the format:

A 31 27 52

B 29 31 58

C 35 36 51

D 34 36 62
