    I'm New...=(

    Ok so, i'm currently trying to make a application that performs similar to a game of hangman.

    i currently have it set up to have the leader of the game choose a word, and when he/she types it in it stores it as a variable, and also stores the length to then tell the players later.

    this is what i have right now:
    Code:
    #include <iostream>
    #include <cstring>
    
    using namespace std;
    
    int main()
    {
     int strikes; // to tell the plyers how many wrong guesses
     int wordlength; //to tell plyers how long the word is
     char guess; //what the players will be defining to play the game
     char gameword[30]; //the designated word from the leader
    
     cout<<"For Game Leader:\nEnter Game Word Here:"; 
     cin.getline(gameword, 25); //leader of game enters the word of the game here
     wordlength=strlen ( gameword ); //stores the length of the word into "wordlength"
     if( wordlength>25){
         cout<<"The Word You Entered Was Too Long For This Game\n";
         cout<<"Please Try Another Word."; //checks to see if word will fit in the string allowed
     }
     else {
         cout<<"CONGRATULATIONS! You Have Chosen A Valid Word\n";
         cout<<"Now You Are Ready To Play The Game\n\n\n"; //tells the leader he/she has chosen a valid word, and it's time to play
     }
     cout<<"For Players:\nThe Game Word Has A Length Of "<<wordlength; //reveals the length of the game word to the players
     
    cin.get();
    }
    what i have works just as i want it, but now i need to get to a point to where i can look directly to the string defined and find individual characters.

    as the title says, i'm fairly new to this. i understand the logic, of most things. SO am i able to analyze the string made by the leader of the game and have, when the player types a single character as their guess to tell the player tht yes or no the letter is there, and there if the letter is there where as in:

    leader chooses hangman as the gameword
    player chooses a
    say yes, and position 2
    then
    player chooses x
    i say no
    and give them 1 strike(u have certain number left)

    To find if the letter is in the word, you want to use std::string::find(). You're probally going to end up stuffing it in a loop so you can return every occurance of the letter in the word, unless you're only using words where the letter occurs once.

    well i can't guarantee that the game leader will always use words with completely unique letters.

    i figure i might have to use the find function, but how do i implicate it into the code i have right now?

    because i have tried using the find thing(with little knowledge of the syntax) and it always produces an error.

    Ok, let's psuedocode a function for you and see if it makes sense.

    Code:
    ContainsLetter(Word, Letter)
    {
        int Positions[Word.Length];
        int SearchIndex = 0, PositionsArrayPositionCounter = 0;
    
        while ((SearchIndex = Word.find(Letter, SearchIndex)) != npos)
        {
            Positions[PositionsArrayPositionCounter] = SearchIndex;
    
            SearchIndex++; // So find() isn't finding the same letter over and over.
            PositionsArrayPositionCounter++; // So we don't overwrite our previous result.
        }
    
        return(Positions);
    }
    Does that make a little bit more sense?

    ummm unfortunately no...

    the ContainsLetter(Word, Letter)... is that part of the code, or just a title of what is going to be going on.

    i see that the the variable positions is going to be a string?
    then ur defining the SearchIndex as 0, but what is the next thing on that line?
    then the loop... how do u know what to put b4 "find". also what is npos?
    after that i think if all my other ?'s are answered to my understanding should be fine.

    i am as we talk here, trying to read a tutorial on the find function.

    Whats up... am I mis-understanding something? Are you just trying to analyze the word and find the user specified letter and where it exists? Why not just go with a simple loop?

    Code:
    for(int i = 0; i < wordlength; i++){
      if(gameword[i] == guess){
        // Letter found.  Output [cout] or store. variable i = character position.
      }
    }  // Done.  Entire word analyzed.
    There is also a function called strchr that locates a specific char within a string which could be used in a loop to find all occurring letters in a string and their locations.

    I have a feeling I'm misunderstanding your goal..

    I think it's a good thing to use the stl functions, instead of more C-like functions as 'strchr'? Here is a good reference about the stl:

    cin.get();
    }
    here, i have it displaying a string array to show the player a visual of the word(given the letters they've guessed)
    the only problem is, it only works if the letters are guessed in order. for example, if the game word is happy, and the first guess is y, it WILL store the letter into the array, but it WILL NOT display it until h,a, and p are guessed.

    ne ideas?

    Instead of using goto, pull out parts of your code into functions, then call those functions.

    1) you have defined 'main' as a function which returns 'int' (and this is correct), so return it. For the main function, return a '0'.

    2) make functions instead of codeblocks, call the functions instead of 'goto'.

    3) make functions instead of codeblocks, call the functions instead of 'goto'.

    4) p = p+1 is equivalent to p += 1 is equivalent to p++

    5) consider using "#include<string>" instead of "#include<cstring>"

    my beginner brain was just blown...

    so instead of having everything under 'main' just make a new block of code? and can u provide and example of a call? do u just use 'cout'?

    ur response #4... why did u put that in there?

    and 5, what exactly does that mean?

    Code:
    #include<iostream>
    #include<string>
    
    using namespace std;
    
    void function1( void)
    {
      cout<< "this is function 1"<< endl;
    }
    
    double function2( double arg)
    {
      double result = arg / 2;
      return result;
    }
    
    int main( void)
    {
      
      cout<< "let's call function1 !"<< endl;
    
      function1(); // empty argument list since function argument list is declared 'void' (empty)
    
      double justanumber = 10;
    
      double result = function2( justanumber);
    
      return 0; // the return value of main is of an 'int' type
    
    }

    just to show you the equivalence... replace p by c and you see what the language's name means ;-)
