Need help with a function in C. [Paid]

[NathanW]

Hi,
I have been doing a hangman project that i have been trying to do in C. i have completed 90% of it but i am stuck on how to do the last two functions. I have tried to so many different ways but i cant seem to work it out.
Any help is greatly appreciated.

#include <stdio.h>#include <stdlib.h>
#include <string.h>
 
 
 
 
int main(int argc, char *argv[]){
 
 
    char word[500];
    int len;
    int guessedLetters[26] = {
      1,1,1,1,1,1,1,1,1,1,1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0
    };
 
 
    len = init(word);
    printf("\nWord = %s", word);
    printf("\nGuessed:  ");
    displayWord(word, guessedLetters, len);
    return 0;
}
 
 
 
 
//picks word for hangman game
int init(char* word)
{
   srand(time(NULL));
   int randomIndex = rand() % 50;
 
 
   const char* words[50] = {
      "array",      "auto",       "break",      "case",       "cast",
      "character",  "comment",    "compiler",   "constant",   "continue",
      "default",    "double",     "dynamic",    "else",       "enum",
      "expression", "extern",     "file",       "float",      "function",
      "goto",       "heap",       "identifier", "library",    "linker",
      "long",       "macro",      "operand",    "operator",   "pointer",
      "prototype",  "recursion",  "register",   "return",     "short",
      "signed",     "sizeof",     "stack",      "statement",  "static",
      "string",     "struct",     "switch",     "typedef",    "union",
      "unsigned",   "variable",   "void",       "volatile",   "while"
   };
 
 
    strcpy(word, words[randomIndex]);
    int lengthOfWord = strlen(words[randomIndex]);
 
 
    return lengthOfWord;
 
 
 
 
 
 
}
 
 
 
 
//Displays word with dashes over un-guessed letters
void displayWord(char *word, int *guessedLetters, int length)
{
    int i;
 
 
    for (i = 0; i < length; i++ ){
 
 
        if(guessedLetters[word[i] - 97] == 1){
            printf("%c", word[i]);
        }else{
            printf("-");
        }
    }
    printf("\n\n");
}
 
 
 
 
 
 
 
 
/****************************************************************************
* Function guessLetter() prompts the user to enter one letter. The function
* maintains an array of guessed letters. The function returns GOOD_GUESS
* or BAD_GUESS depending on whether or not the letter is in the word.
****************************************************************************/
int guessLetter(char* word, int* guessedLetters)
{
}


/****************************************************************************

****************************************************************************/
int isGameOver(char* word, int* guessedLetters, unsigned wrongGuesses)
{
}

I have experience in Java but i cant seem to wrap my head around C. Any help with the last two functions (isGameOver() and guessLetter()) would be very much appreciated. Will send some $$ over as well.

 

I mean I'm not going to write the functions for you, but I'll give you a detailed outline on how to get them done.

guessLetter:
- Prompt use to enter a letter, store it as a temp char
- Check entered char against array of chars already guessed so that the user can't duplicate guesses
- A C-String is just an array of chars, so loop through the correct word like it's an array and check if the guessed char matches the currently selected char in the C-String
- If the loop comes up empty, return BAD_GUESS (let's say an int value of 0), or 1 for GOOD_GUESS
- Add 1 to a global "good guesses" variable, so we can keep track of how many good guesses we have. Make a "bad guesses variable" to keep track of wrong guesses too.

isGameOver:
- Run isGameOver every turn to check if the game is over yet or not
- If our "good guesses" variable is equal to the length of the word we're playing with, the game is over
- If our "bad guesses" variable is equal to the length of the word we're playing with, the game is over

Feel free to PM with further questions
