String printing extra values C programming

Question

I am currently working on a game in class but have some problems when printing and checking strings. Essentially it is hang man and I need to print the word as just _ (underscores) with spaces separating each underscore. I am just filling in a skeleton code and the code I had to fill in looks like:

initializeBlankString(const int numLetter, char revealedLetters[25])
{
  int i;
  for(i=0;i < numLetter; i++){
    revealedLetters[i] = '_';
  }
 revealedLetters[numLetter - 1] = '\0';
}

printWithSpaces(char revealedLetters[25])
{
  int i;
  for(i=0;i<(strlen(revealedLetters));i++){
    printf("%c ", revealedLetters[i]);
  } 
}

revealGuessedLetter(char word[], char revealedLetters[25], char guess)
{
  int i, n = 0;
  for(i=0;i<strlen(word);i++){
    if (word[i] == guess){
      revealedLetters[i] = guess;
      n = 1;
    }
  }
  return n;
}

checkGuess(char word[25], char revealedLetters[25])
{
  if(word == revealedLetters)
    return 1;
  else
    return 0;
}

I have tried lots of different things and I am unable to be successful. The problems would is when the word is something like unix it will show _ _ _ _ + r 6 _ instead of just _ _ _ _ I escaped I thought but it doesn't look like it.

Function calls look like this:

initializeBlankString(strlen(word), revealedLetters);
printWithSpaces(revealedLetters);
charRevealed = revealGuessedLetter(word, revealedLetters, guess);
won = checkGuess(word, revealedLetters);

solution:

void initializeBlankString(const int numLetter, char revealedLetters[25])
{
  int i;
  for(i=0;i < numLetter; i++){
    revealedLetters[i] = '_';
  }
 revealedLetters[numLetter] = '\0';
}

void printWithSpaces(char revealedLetters[25])
{
  int i;
  for(i=0;i<(strlen(revealedLetters));i++){
    printf("%c ", revealedLetters[i]);
  } 
}

int revealGuessedLetter(char word[], char revealedLetters[25], char guess)
{
  int i, n = 0;
  for(i=0;i<strlen(word);i++){
    if (word[i] == guess){
      revealedLetters[i] = guess;
      n = 1;
    }
  }
  return n;
}

int checkGuess(char word[25], char revealedLetters[25])
{
  for(int i = 0; i < strlen(word);i++){
    if(word[i] != revealedLetters[i])
      return 0;
  }
  return 1;
}

The position for the final '\\0' is miscalculated in initializeBlankString :

revealedLetters[numLetter - 1] = '\0';

Should be:

revealedLetters[numLetter] = '\0';

There are many more problems with your code:

• Modern C mandates function return types. void for the first 2, int for the last 2.

• You cannot compare char arrays with if(word == revealedLetters)
