errortrap

[nin]

how do u errortrap words?
what i mean is that in my game , for the answerable questions, the user can type anything they want but i only want them to type numbers and not words.
And if they type words, it should errortrap it.
so how can i do that?

I believe strintok and strrealok will suit you perfectly.

wats that?

Press F10 while in Turing.

But basically strintok (x:string) is a function that returns whether 'x' is in the correct format for an integer type, and strreal does the same thing but for real numbers.

Ex:

code:

var s : string := "Hello" var n : string := "5" var r : string := "5.55" put strintok (s) put strrealok (s) put strintok (n) put strrealok (r)

So to check if an answer to a question is in the correct format (a.k.a an integer) use:

code:

var answer : string put "What is 5 + 5?" get answer : * % Numbers are < one word, but the  : * will keep the user from skipping lines if strintok (answer) and strint (answer) = 10 then     put "Correct!" end if

Hope that clears it up,

n if u were keppomg trck of the score how would u do that?

[Expirant]

Well, think about it. When does their score increase? When they get an answer correct, right? So...where in your code does it check if the answer is correct?
So if they get the answer correct, increase the score by 1. At that point in your code, you would have score += 1 (or score := score + 1). In the code I wrote, it would be:

code:

var answer : string var score := 0 put "What is 5 + 5?" get answer : * if strintok (answer) and strint (answer) = 10 then     put "Correct!"     score += 1 end if put "Final score: ", score

...

Think about it for a while, and if you're still having trouble, ask again.
