I am working on a routine management system. I just thought like this, the binary file will have 8 lines, 1st line for password matching (8 characters fixed, drama for college), rest of the lines will have the timetable for each day and each line no corresponds to the day no.
Now I made 1 TimeTable Class and a Inherited class Period. Timetable holds day no and Period holds all the details of a period like faculty id, time, sub code, etc.
Now, problem is, how can I write & read the whole data to & from the binary file?
Also, how can I display the whole routine like spreadsheet?
I separated the modules as I have also made login & signup features (module) in my code.
To view the full project you can check my GitHub Repo: https://github.com/ArchismanKarmakar/TimeTable-AK
UPDATE:
Well I just made the modules for faculty. After research, I found that saving a whole routine & getting it in formatted form is impossible with binary files. So, I just switched to CSV / TXT files.
Just made the Faculty modules:
I made the facultyId.csv like this:
id,name,age,phone,email,gender
a12,archisman,0000000000,test#test.com,M\n
But I wanted to represent the whole 2D matrix of routine in the CSV file. Is that possible?
