Nonfunctional function

[Evandb]

Hi all, I wrote this function for a hangman game I am making. This function is supposed to take in prompt for a letter as a guess then check it against two arrays, one wrongly guessed letters and one with right guesses. What happens is that it asks for a guess then you enter a letter and it just stops. You can keep hard returning, but it doesnt do anything past that.

Thanks for the help in advance,

Evan

int getGuess(char display[], char wrong[], int misses) 
{ 
char guess; 
int valid; 
printf("Enter a character to guess:"); 
guess=scanf("%c",&guess); 
valid=1;

while(valid==1)
{
if(guess>='a' && guess<='z')
   {
   while (*wrong != '\0' && *wrong != guess )
    {    wrong++;

    if( *wrong == '\0' )
        valid=1;
    else
        valid=0;
   }
while (*display != '\0' && *display != guess )
    {    display++;

    if( *display == '\0' )
        valid=1;
    else
        valid=0;
   }
  }
if(valid==0)
   {
    printf("Try again!");
   }
}
return guess;
}

If you keep wrong and display as proper strings, then simply use
if ( strchr( wrong, guess ) != NULL ) // guess is in wrong
