to TI IT list

Hi all,

I want to create a program in which participants are asked to enter a 4 digit code.

It will be a combination so I need it to say Correct or incorrect.

I want people to get 3 attempts

I am having two issues.

I cant clear the value of the code attempt so the old value appear

Tried using DelVar doesn't seem to work

Also more importantly I need to be able to hide the code to enter so students cant simply look at the program to get the answer

help appreciated

Define lockedbox()=

Prgm

:Local comb

:Disp "Enter your code below you have 3 attempts"""

:tries:=0

:correct:=false

:While tries<3 and not correct

: comb:=0

: Request "End Combination",comb

:Disp comb

:If comb=2345 Then

: Disp "correct"

: correct:=true

:Else

: Disp "wrong"

: tries:=tries+1

:EndIf

:EndWhile

:If not correct Then

: Disp "No more attempts. Goodbye."

:Else

: Disp "You're in!"

:EndIf

:EndPrgm

Do good,

John

Suggestion: generate a random combination!

Do good,

Hi John,

thanks for that I need to be able to set the combination.

I have 4 separate activities which students complete to determine the combination. I often use a combination padlock on a toolbox with prizes in the toolbox.

Now how to hide the variable.

Re: “Now how to hide the variable.”

That will be a challenge! All you’d have to do is add a Disp <var> to the program to reveal it.

You could put the combination into a document in the form of a Question and make the doc an exam to hide the answer…

Do good,

John

You could conceal the program (delete the page containing the Program Editor app), clear the Calc app’s history to have a blank Calc app, then send the file to the students.

They would have to press [var] to paste the program name and then run the program.

But a clever student can always add a Program Editor, open the program and reveal the code.

I think the best solution to keep the code hidden would be to write the program using Lua!

Do good,

John
