Question

please write C++ code to finish R0,R1,R2

Introduction In this assignment, you are going to develop a "Schedule Book System that runs in the command line environment. The system stores the schedule of events input by user and allows users to add view or delete events. You can assume that the system can at most store 100 events Each group is required to write a Win32 Console Application program called ScheduleBook.cpp The requirements are listed below. RO When the program starts, the console should display a welcome message, followed by the Main Menu of the program. User can enter the options of the corresponding actions (see RI to R6 below) Welcome Message designed by your group - Main Menu * 11) Add one event [2] Delete one event 131 Add events in batch [4] Show events 15) Credits 16) Exit Option (1 - 6): 11 Add one event When the user inputs I in the Main Menu, the user should be prompted for entering the following information about the new event to be created: SER2012 19-20 Semester 2 - Group Project • Event Title • Event Date • Event Start Time • Event End Time • Event Type The following requirements related to adding an event should be followed. RII Input checking The following validity check regarding the input data should be carried out. • "Event Title" should be a string. You can assume ths inrut is almost 40 characters
