checking strings

-----------------------------------

Hey there, is there a way to check if a string contains a certain set of characters. Not if a string is equal to a certain set of characters but for example, if I have a variable string that is "Vanilla cookie with sprinkles, peanuts, almonds", I want to have an if statement where the condition is whether a variable has "peanuts" anywhere in the string. How can I do this? Thanks.

Here i made you a very small program which dose what you ask.


var text: string := ""
var word: string := ""

fcn search (text_: string, word_: string): boolean
    if index(text_,word_) not= 0 then
        result true
    else
        result false
    end if
end search

get text:*
get word

if search(text,word) = true then
    put word, " is found in: ", text
else
    put word, " is NOT in: ", text
end if


1) its case sensitive
2) its not flexible

Ill let you optomize it...

you can use the index method. for more info on strings, check out cervantes' tutorial  :wink:

Thanks TokenHerbz. Can this be used in arrays? For example:
var name, final : array 1 .. 12 of string

for x : 1 .. 12
    fcn search (name_ (x) : string, final_ (x) : string) : boolean
        if index (name_ (x), final_ (x)) not= 0 then
            result true
        else
            result false
        end if
    end search

    if search (name (x), final (x)) = true then
        put final, " is found in: ", name (x)
    else
        put final, " is NOT in: ", name (x)
    end if
end for
Where name(1 - 12) and final(1 - 12) are defined earlier in the code?

errr... you don't put functions in loops.... read up on the function tutorial in the Turing Walkthrough, right now though, if you are only looking for the string once or twice, you could get away just doing the index function in your main line.

TokenHerbz... your not really supposed to just give away the answer to the person, you should know this by now.

its not an answer if he dosn't know how to use it...

its a guild line, he'll have to play around with it and learn it, understand it to optomize it for the whole thing he needs it to do.

fcn search (text_: string, word_: string): boolean
    if index(text_,word_) not= 0 then
        result true
    else
        result false
    end if
end search 

Doing way too much work here.

fcn search (text_: string, word_: string): boolean
    result index (text_, word_) not= 0
end search

Well actually, I need it to check a number of variables defined by the user. I currently have:
get number
var project : array 1 .. number of string

for x : 1 .. number
project(x) := project(x) + other(x)
end for
And then I need for certain strings added by 'other' in project(x)
