School timetable
A handy reference for students.
At the beginning of the academic year students are issued with a timetable to show which lessons they have each week. In this program a school week is five days, each with six lessons, but this could easily be changed.
It is helpful for students to create their own copy of their timetable as a handy reference. This program allows the user to create, save, load and output a timetable.
Assessment
These objectives get progressively harder. Attempt as much of the program as you can in the order presented below. Remember to use a comment to describe a subpprogram, selection or iteration.
Use this boilerplate code as a starting point:
Success Criteria
Setting up and visualising the table
- In the main program declare a 2D array called `timetable` of six lessons each of five days, with all elements initialised to be "---".
1 mark
You can visualise the initial timetable like this. Each row is a day 1-5 and each column is a lesson 1-6:
1 | 2 | 3 | 4 | 5 | 6 | |
|---|---|---|---|---|---|---|
1 | === | === | === | === | === | === |
2 | === | === | === | === | === | === |
3 | === | === | === | === | === | === |
4 | === | === | === | === | === | === |
5 | === | === | === | === | === | === |
User menu
- Define a subprogram called `menu` that takes the array `timetable` as a parameter.
- Ouput five choices for the user: 1. output timetable, 2. Edit a lesson, 3. Load, 4. Save, 5. Close.
- Ask the user to input a choice from 1-5.
- Repeat the step above until the user makes a valid input.
- Use a loop to repeat all the steps in this subprogram until the user chooses "5".
- Add a call to `menu` to the main program.
6 marks
Edit a lesson
- Define a subprogram called `edit_lesson` that takes the array `timetable` array as a parameter.
- Prompt the user to enter the day and lesson they want to edit.
- Prompt the user to enter the name of the subject.
- Store the data in the timetable array.
- Output that the lesson has been updated.
- Return the timetable.
- Add a call to the `edit_lesson` subprogram in the `menu` subprogram if the user chose option 2.
7 marks
Formatting the subject name
- Define a subprogram called `subject_code` that takes the name of a subject as a parameter.
- The subject is changed to uppercase.
- The subject should be three characters, padded with spaces if it is less than three characters. E.g. Maths is Mat. PE is PE followed by one space.
- Return the formatted subject.
- Change the subprogram `edit_lesson` so that the subject code is written to the array, not the input the user entered.
5 marks
Loading a timetable from a file
- Define a subprogram called `load` that takes the array `timetable` as a parameter.
- Load the timetable from a CSV file called `timetable.txt` and store the data in the timetable array.
- - Add a call to the `load` subprogram in the `menu` subprogram if the user chose option 3.
3 marks
Saving the timetable to a file
- Define a subprogram called `save` that takes the array `timetable` as a parameter.
- Save the timetable array to a CSV file called `timetable.txt`
- The format of the CSV file must be compatible with the `load` subprogram so that the timetable can be loaded and saved.
- Add a call to the `save` subprogram in the `menu` subprogram if the user chose option 4.
4 marks
Saving the timetable to a file
Displaying the timetable
- Define a subprogram called `output` that takes the array `timetable` as a parameter.
- Output the timetable in the format shown below. Note the row and column headings plus the lesson separators.
- Add a call to the `output` subprogram in the `menu` subprogram if the user chose option 1.
