Program doesnt work properly.

Hello guys!

I wrote this program that compares two lines and says if they are equal or not. But there is a twist: A star can replace any character and even any Number of characters (like whole words).

My program nearly works. It returns everything correctly apart from when there is a mistake AFTER the star.

So:

Hello World
Hello World
= Match.

Hello World
H*o World
= Match.

Hello World
*World
= Match

But
Hello World
Hello W*sfd
Shows it matches, but it shouldnt!

Any help, tips, advice is appreciated.

Code:

int     match(char *s1, char *s2)
{
  int   s1length;
  int   s2length;
  int   is_match;
  int   y;
  int   x;
  int   i;

  s1length = strlen(s1);
  s2length = strlen(s2);
  is_match = 0;
  y = 0;
  while (y < s1length)
    {
      i = y;
      if (s2[y] == '*')
        {
          while (s1[y] != s2[i + 1])
            {
              if (s1[y] == '\0')
                {
                  is_match = 1;
                  break;
                }
              y++;
            }
          break;
        }
      if (s2[s2length - 1] == '*')
        {
          is_match = 1;
          break;
          }
      if (s1[y] == s2[y])
        {
          is_match = 1;
          y++;
          continue;
        }
      else
        {
          is_match = 0;
          break;
        }
    }
  return (is_match);
}

int     main()
{
  int   x;
  char array1[] = "Hello World";
  char array2[] = "Hello W*ef";
  x = match(array1, array2);
  printf("%d", x);
  return (0);
}

Code:

while (s1[y] != s2[i + 1])
{
  if (s1[y] == '\0')
  {
    is_match = 1;
    break;
  }
  y++;
}

In your example, s2[i + 1] would be 's', but there's no 's' in s1. You'll hit the end of the string, and your logic says that this is a match. Since you're matching strings exactly with the exception of the wildcard, if s1[y] is '\0', s2[i + 1] should be '\0' as well for there to be a legitimate match in this case.

Didnt solve my problem :/

It still considers anything after a wildcard a Match.
So if it is like this:
Hello World
Hdllo W*orld

It works properly and shows that it is Not a match. But

Hello World
Hello W*sef

Shows it matches. So after a wildcard it just shows everything as match.

Hey.

I solved my problem, so thank you anyway.

But I ran into a different one... I cant count the number of matches possible :/

And we can't help anymore because your code is different now, but you didn't post it.
