Hey I am new to programming and as a college project I want to build schedule maker. I don't know how to start can anyone tell me how to create a similar tool like shown in this site
First you need to write a console program that stores dates/times/durations and schedule items in the form of strings, for arguments sake. Combine the two in a vector, map or array of struct/class schedule objects.
Functionality would include add/edit/delete a schedule item(s) and a notify/list schedules.
Once you have that working there are plenty of GUI based classes around, QT, MS stuff and IDE's where you can design a GUI interface and tabulate the schedule.
Try Github/Sourceforge and the many tutorial websites if you want useable code. That's a Google job!
