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.

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:

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.

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.

Good programming practices

• The subprograms and main program sections are signified with comments.
• The subprograms have a comment to describe their purpose.

If you score less than 25 you need more practice at levels 1-9 before you continue to the next level.

Restricted automated feedback

Automated feedback for this assignment is still under construction. Submitted programs are checked for syntax errors and their source code is checked for potential errors, bugs, stylistic issues, and suspicious constructs. However, no checks are performed yet to see if the program correctly implements the behaviour specified in the assignment.
