hello there, i got problem with my code, when i starting to guess a letter and hit the enter, the letter i've guess is not printing in the blank i made. can someone help me to fix the code? thanks.

Code:

int main(){
    int i;
    int j;
    int x=0;
    char word[30];
    char undscr[30];
    char length;
    char letter;
    
    printf("enter a word: ");
    gets(word);
    
    length=strlen(word);
    undscr[x]='_';
    for(i=0;i<length;i++)
    {
        printf(" %c", undscr[x]);
    }
    
    printf("\n\nguess the letter: ");
    scanf("%c", &letter);
    for(j=0;j<i;j++)
    {
        if(letter==word[i])
        {
            undscr[i]=word[i];
        }
    }
    
    getch();
    return 0;
}

reply for this please, i really need your help.

Try this:

Code:

#include <stdio.h>
#include <string.h>
#include <conio.h>
 
 int main(){
   int i;
   int done=0;
   int good=0;
   char word[30];
   char undscr[30];
   char length;
   char letter;
    
   _gotoxy(1,3);
   printf("enter a word: ");
   gets(word);
    
   length=strlen(word);
   for(i=0;i<length;i++) {
      undscr[i]='_';
   }
   while(!done) {
      _gotoxy(1,5);
      for(i=0;i<length;i++)
      {
         printf("%c ", undscr[i]);
      }
      if(good>=length) {
         done=1;
         break;
      }

      printf("\n\nguess the letter: ");
      letter=_getch();
      printf("%c",'\b');
      
      for(i=0;i<length;i++)
      {
         if(letter==word[i])
         {
            undscr[i]=word[i];
            good++;
         }
      }
   }
   _gotoxy(1,9);
   if(done)
      printf("You guessed it!\n\n");
   printf("Hit Enter When Ready\n");
   getchar(); 
   return 0;
}

[Linker error] undefined reference to `gotoxy' , im using dec c++ as a compiler.

Remove the underscore from in front of _gotoxy's. gotoxy() is part of conio.h, but my compiler uses the leading underscore for it nowadays.

its working thanks!!...

but its only works in TurboC not in DevC++.

Does Dev C support the conio.h include file? Do you have a conio.h file in your header file directory?

I don't have Dev C, so i can't help you with those problems.

If you are using Windows, you can use SetConsoleCursorPosition(), (you may have to include "windows.h"), instead of gotoxy(), but I'm not sure how to get a key stroke like getch(), in Windows. You can also skip the gotoxy() and getch(), and make it either a "rolling" screen presentation of the game input and output, or clear the screen between letters being entered. That will give the game a bit of a "blinking" look, but it might be OK.

I have heard that NCurses supports a lot of the same functions that conio.h does, but I haven't used it myself.
