C++ Word Guess game almost done, few problems ?

[moosemb]

I'm making a Word Guess game.
RULES:
-Player1 will enter a word of any length for Player 2 to guess. [DONE]
-Player 2 will have 5 letter guesses and 5 word guesses total. [DONE]
-Ignore case; ex. If user enter 'T' display it as lower (without using toupper/tolower)[STUCK]
-If user guesses correct letter, replace dash(es) with letter, and what position; ex: "testing" and Player2 enters 'T' then output should be "You guessed the letters at 1 and 4 correct letter guess correct. You have 4 letter guesses remaining. Enter your first word guess".

PROBLEMS:
-Program doesn't ignore case [need to fix]
-If the letterguess is correct, or incorrect, count it as 1 letter guess and have them attempt their first word guess. DO not worry about a user guessing letters multiple times, just count it as a used guess.
-If I run the word: "testing" and I enter "T" it should display "You guessed the correct letter at 1 and 4. Enter word guess" / instead if I enter 'T' it displays "Wrong letter".... if I enter 't' it only reads the first t and not the fourth.

Any help appreciated. I am so close to being done, just stumped.

the difference between 'a' and 'A' is constant. a char is just an integer. you can do your own toupper type function (or, just inline if you only need it in a place or two).

for multiple letters, you need to flip them all in a loop ... for all the letters in the word, if it matches, replace the dash with the letter.

@jonnin instead of using a char for letter guess, I'm using a string. I couldn't figure out how to make char = word.length().

would you mind elaborating a bit more?

1. I have a function to ignore case, but it is not working, and I don't know how to go about fixing it.
2. Even if I dont guess uppercase, and I guess a lowercase 't' it will only read the first instance, and I cannot figure out how to make it check for every instance of the letter.
3. I have to add word guesses, and I cant get that to work either.

I'm not just trying to beg for answers, but I've been working on this for over a week, and my time is almost up.

for(int i = 0; i < somestring.length(); i++)
  if(somestring[i] == guess)
     dashstring[i] = guess;

if(guess == somestring[i] || guess+('a'-'A') == somestring[i]) //case ignored

and
if(wordguess == somestring)
//winner, they guessed right!

#include <iostream>
#include <iomanip>
#include <cctype>
#include <string>

using namespace std;
bool checkWord(string word, string guess) // check word and guess
{
    int counter = 0;
    for (int i = 0; i < word.length() && i < guess.length(); i++) // ignore case
    {
        if (tolower(guess[i]) == tolower(word[i]))
            counter++;
    }
    return counter == word.length();

using tolower is the only way I can get it to work.. however thats the only thing I cant use.

Nothing stopping you writing your own version!
