Okay I have managed to finish everything. However, my output for average minutes and average hours is wrong for some reason. I have looked over my code multiple times and I cannot figure out what the problem is. I would appreciate any help.
Here is my code. Can you tell if anything is wrong in the logic or the Calculate average methods?
/* This program prompts the user to enter data for 10 employees only. The program will
prompt the user to enter the last name of the employee, the hour they started (in military time),
the minute they started, the hour (in military) that they ended, and the minute they ended work. The
program will output the employee's last name, the hours they worked, and the minutes they worked that
day in a nicely formatted column. We are assuming everything has been validated and this program works
only for the day assigned. No employee works past to the next day.*/
