Code abruptly stopping for no reason.

[Jari.C]

What is it you are trying to achieve?
I am trying to write a +,- and * quiz.


What is the problem you are having?
There is a part in the code where it asks for + - or * and when I select addition the code works fine but when I select subtraction the code just suddenly ends.


Describe what you have tried to solve this problem
I've done general troubleshooting


Post any relevant code (You may choose to attach the file instead of posting the code if it is too long)
var Level, Level2 : string
var answer, counter, num1, num2, num3, num4, wins, answer2 : int
counter := 0
wins := 0


%asking what level they want
put "Choose multiplaction, subtraction, or addition " ..
%getting the level
get Level

% running the thing they wanted the additon level
if Level = "addition" then
%looping the program
loop
% getting the numbers for the randints
num1 := Rand.Int (0, 30)
num2 := Rand.Int (0, 30)
%displaying the addition question
put num1, "+", num2
%asking for the question
get answer
if answer = num1 + num2 then
put "You're correct"
counter := counter + 1
wins := wins + 1

else
put "You were wrong"
wins := wins + 0
counter := counter + 1
exit when counter = 20

if Level = "subtraction" then
loop
num1 := Rand.Int (0, 30)
num2 := Rand.Int (0, 30)
put num1, "-", num2
get answer
if answer = num1 - num2 then
put "You're correct"
counter := counter + 1
wins := wins + 1
else
put "You're wrong"
wins := wins + 0
counter := counter + 1





end if
end loop
put "You won ", wins, " out of 20 games"
end if
end if
end loop
end if

Edit: I haven't written the * part yet.

Look at your code. There's a huge block of an if statement that says if Level="Addition" then do stuff. Thats it. If you dont write addition, nothing happens.

[Jari.C]

What do you mean? I also have a if Level = "subtraction" thing, how do I make it so I can choose multiple options.
Edit : Sorry for being so new at this

[Raknarg]

Look how your code indents:

Turing:

var Level, Level2 : string var answer, counter, num1, num2, num3, num4, wins, answer2 : int counter := 0 wins := 0 %asking what level they want put "Choose multiplaction, subtraction, or addition " .. %getting the level get Level % running the thing they wanted the additon level if Level = "addition" then     %looping the program     loop         % getting the numbers for the randints         num1 := Rand.Int (0, 30)         num2 := Rand.Int (0, 30)         %displaying the addition question         put num1, "+", num2         %asking for the question         get answer         if answer = num1 + num2 then             put "You're correct"             counter := counter + 1             wins := wins + 1         else             put "You were wrong"             wins := wins + 0             counter := counter + 1             exit when counter = 20             if Level = "subtraction" then                 loop                     num1 := Rand.Int (0, 30)                     num2 := Rand.Int (0, 30)                     put num1, "-", num2                     get answer                     if answer = num1 - num2 then                         put "You're correct"                         counter := counter + 1                         wins := wins + 1                     else                         put "You're wrong"                         wins := wins + 0                         counter := counter + 1                     end if                 end loop                 put "You won ", wins, " out of 20 games"             end if         end if     end loop end if

It will look at this line:

if Level = "addition" then

If it is true it will run all that stuff inside. If it is not true, it will find the first end if on the same level (the very end of your program)

Raknarg got it covered. I'd like to share a style that I find useful.

It's hard to make sense of deeply nested logic. This part?

code:

end if end loop put "You won ", wins, " out of 20 games" end if end if end loop end if

Very difficult to make changes to correctly. Indentation takes you a long way there; more so with an editor that will match up the indentation levels... I like to label my terminating statements

code:

put "You won ", wins, " out of 20 games"             end if % subtraction         end if % answer = num1 + num2     end loop end if % addition

Don't have to label everything. Just enough to help you navigate.

So is there a way to make it so it will run subtraction or addition? Instead of only running if addition is chosen.

[Raknarg]

If the addition clause fails, then maybe you should include a subtraction clause as well

Oh I understand it now. Thank you guys for your help
