Homework & Coursework Questions

Are you sure your question while loop is working? What happens when you get "invalid choice"?
When you choose Question 2, is it the correct one displayed?
And ctsgnb is right, in order to do what you want, you ought to finish your answer function - and use it...

thanks,saw your reply but I tried adapting the lines of code to my codes but did not work

Please can you highlight the line of code that will work for me in the referred to code.

Thanks

yes, i think it's question while loop is working.
What is displayed after the date is "Enter question number,N for next,P for previous or Q for done", instead of displaying the first question.
When it displays Invalid Choice, it then displays "Enter...." again for the following questions

It displays what: "Enter your choice" again or returns to asking you to choose a new question... ?

I hope i'm not of order by showing you the output from the screen shot

Enter question number, N for next question, P for previous question or Q for done

Enter your answer :

Invalid choice
Enter question number, N for next question, P for previous question or Q for done
n
1. How would you create a new directory called docs?

a) makedocs
b) mkdir docs
c) create docs
d) none of these

This is the exact view of the scree shot

So you can see also, there is something not quite right:

Code:

Wed Dec 15 21:31:01 GMT 2010
Enter question number, N for next question, P for previous question or Q for done
n

Lets say you are at the beginning of execution and entered next, you have no values to compare with so you should force the program to call Question 1 and display it...
Why isnt it displaying a question since its in now the answer loop?
More strange - in answer loop, it judged the answer as invalid - It just NOT come out of loop but display and accept your choice again (till a valid choice...).
