Re: C++ Programming issue

#11

Apr 25th, 2007

I've reworked the full program a little bit. Note the new header file which eliminates the need for the sameWord function. Really look at and understand the use of multiple conditions in the while loop and the use of flags. The code as presented is untested and comes with no warrantees.

why not better work it out an even more simple way... get your string's length and create an array of characters as long as the string, which will substitute your string in the rest of the program. This way you can compare your guess individually with each element in the array...

i don't know... maybe it can make things a bit more simple...

well, it's pretty near to what i said, though that gave me an idea... why not make a fusion of both ideas and create two individual arrays with the size of the string: one with '_' in each element, and another one with the letters in the string in it. When the user's guess is correct, you enter a for loop and assign the user's guess letter into the matching places in array1 (the one with '_') and array2 (the one with the letters)...

get it?

Re: C++ Programming issue

#16

May 1st, 2007

actually this is not finished. I found out that I forgot to make it case insensitive and also I need to keep track of an alert on repeat guesses.

However the issue I am having is with case insensitivity.

I cannot seem to get it to work. The closest I can get is as follows:

      cout << "The word was: " << getWord << endl;
    }

    return 0;
}

However this loads up the ____ with all the same letter for instance:
When the mystery word is "Antique" you guess "A"
and it outputs "Aaaaaaa" then you guess "n" it outputs "nnnnnnn"
and so on.

I need it to be case insensitive and at the same time I need to output characters EXACTLY as the player enters them. So if they put in AnTiQuE it comes out as such even if the word was "Antique" They need to be able to use any combination of capital and lowercase letters and have it return correct as soon as it it guessed.

Further the code above for does not return a "correct" when the word is guessed, I think it has to do with Ascii values not matching.

Any help or guidance on how to acheive the desired final results would be greatly appreciated.

this may require you to check your capital letters in a separate array...

my idea of a simple process to do this is the next one:

1.- create an array that includes all capital letters.

2.-inside a loop, compare all of the letters in the string to both arrays (capital and non-capital letters), and convert all letters in the string to non-capital letters, so that you won't have any trouble further...

3.- to make it trouble proof, compare all of the users inputs to both arrays in a loop, and convert all inputs into non-capital letters

4.- compare the input you just converted with the word you want the user to find...

actually it was much simpler than that. the issue was here
