Question

Your swim school has two swimming instructors, Jeff and Anna.Their current schedules are shown below.

These are the times they are busy, the possible time slots are 11-12,12-1,1-2,2-3
Jeff- Mon- 11-12, 2-3 Tues- 11-12,12-1,1-2,2-3 Wed- 12-1,1-2,2-3 Thurs- 12-1
Anna- Mon- 11-12,1-2,2-3 Tues- 11-12,12-1,1-2 Wed- 2-3 Thurs 11-12,12-12-3

Write a program with array(s) capable of storing theschedules. Create a main menu that allows the user to mark a timeslot as busy or free for either instructor. Also, add an option to output the schedules to the screen. Next, add an option to output all time slots available for individual lessons ( slots when atleast one instructor is free). Finally, add an option to output all time slots available for group lessons ( when both instructors arefree).

I know this is time consuming but please help, i am using microsoft visual C++ express 2010
