Thread: Hangman Project Problem

Hi there. i got stuck with this code. i can't get the right code for the loop to put the letter into the blank. Can anyone help me here.
thanks a lot.

Code:

printf("enter a word to guess: \n");     do{
           c=getch();
           switch(c)
           {
               case '\r':
                    break;
               case '\b':
                    printf("\b \b");
                    if(x>0) --x;
                    break;
               default:
                       printf("%c", '*');
                       word[x++]=c;
                       break;
           }
        }while(c != '\r');
        word[x]='\0';
      
      system("cls");
        
     length=strlen(word);
     undscr[x]='_';
     printf("\n\nthe word to guess is: ");
     for(undrscr=0;undrscr!=length;undrscr++)
     {
         printf(" %c", undscr[x]);
     }
     
     printf("\n\nguess a letter: ");
     scanf("%s", &guess_letter[x]);
