I have a string sz[] = "abcdefghijklmnopqrst", and how can I find a single char in this string? containi(), equal() or ? What am I suposed to do?

Thanks !

PHP Code:

/*
  new bool: bContain = StringContainChar( "abcdefghijklmnopqrstu", 'k' );

  bContain will be true because 'k' exists in string.
*/

StringContainChar( cLine[ ], iChar )
{
  static i;

  for( i = 0; i < strlen( cLine ); i++ )
    if( cLine[ i ] == iChar )
      return true;

  return false;
}

containchar(const haystack[], needle, bool:case_sensitive=true) {
    new needleString[2];
    needleString[0] = needle;
    
    return strfind(haystack, needleString, _:case_sensitive);
}

strfind - Finds a string in another string. Returns -1 if not found.

containchar(const haystack[], needle, bool:case_sensitive=true) {
    new needleString[2];
    needleString[0] = needle;
    
    return (strfind(haystack, needleString, _:case_sensitive) > -1);
}

or

containchar(const haystack[], const needle[], bool:case_sensitive=true) 
{
    return (strfind(haystack, needle, _:case_sensitive) > -1);
}

Right. I was mimicking the contain() functionality but didn't want to make 2 functions for insensitive.

My point was you are checking the return value of strfind() to see if needle was found in haystack, it would always return true EXCEPT if the needle was the first character in haystack. You need to include the > -1 condition, which would also be needed with contain[i], they also return -1 if nothing found.

That's based on how the function was used.

If used like

if(containchar("abcdefg", 'a')) {
    //
}

Then you would be right. However, I was assuming the author would know how to use functions which return the index since contain() was mentioned in the first post.

Alright, I understand your intention now..and figured you knew how strfind() worked.

If it was purely a string containing flags (a-z) would it be better to convert to a bitsum and use the bit and operator?

Unsure of the performance difference between read_flags() and strfind().
