Comments, which is essential for understanding, maintenance, explanation, memory and other good stuff.
User interface, how the program should interact with the user.
Advice
Are you looking for files? See the top line of the Programme page.
Exercises to be handed in
In all these exercises, start with writing pseudo code first and the program after. This is how you should do normally.
The pseudo code is part of the hand-in.
- Returning to last weeks exercise 4, where you had to ask for a file name and you program would then calculate the average of the numbers in the file. Do the same this time, except you have to continue to ask for file names and calculate the average until you enter nothing - no file name. Test on the same files as last time.
