    {
    FILE *inptr;
    inptr= fopen("words.txt","r"); //Words.txt opened and read for use
    fscanf(inptr,"%s", word_to_guess);//get word from file
    printf("%s", word_to_guess);
    }

    	if(equal == 0)
    	{
    		return *result=1;
    	}
    	if(equal != 0)
    	{
    		return *result=0;
    	}
    
    
    }


    Ok basically I am wracking my brain on trying to figure out where to go from here in order to properly display my guessed_letters array, and add the guessed letters each time the user inputs a guess, and to keep the entire program running while the user doesnt use the global max incorrect guesses of 6 and the word is not guessed correctly. So far this will run, read the word from words.txt, and if you input the correct word it will terminate properly. My assignment requires that at all times the user inputted guesses show, incorrect or correct along with the *'d word of what they are trying to guess.

    Any sort of insight will be highly appreciated

    You could have an array - I'll call it used[], which has 26 elements in it 0-25.

    It's a boolean thing - every number that is guessed, gets a one put into the used element which corresponds to it's letter value (where A = 0, through Z = 25).

    now showing the used letters is easy

    For each new game, initialize the used array to all zero's. Then

    In pseudo code:
    Code:
    for 0 to 25
      if(used[index] == 1)
        print the letter corresponding to that index - it's been used already.
    end of for
    You get the letter's corresponding number by first, making the letter uppercase (lower is fine also, but this example is uppercase), and then subtracting A from the letter:

    corresponding number = Letter - 'A'

    I understand the logic behind that. However I guess my main issue lies in that I cannot for the life of me figure out how I should structure my functions so that I can continue to take input until they are out of guesses, or the word is guessed. Either way the guessed letters have to be displayed everytime a guess is made, but I can't get that if I can't figure out how to structure the rest of my functions >.>

    I think I am just overthinking alot of this and it's not helping me at all..been very frustrated -.-
