[Guest claudiuhks]

trim va elimina impuritatile si spatiile libere unei propozitii proaspete citite dintr-un fisier!

void trim( char *cInput )
{
  char *cOldInput = cInput, *cStart = cInput;

  while( *cStart == ' ' || *cStart == '	' || *cStart == 'r' || *cStart == 'n' )
	cStart++;

  if( cStart != cInput )
	while( ( *cInput++ = *cStart++ ) != '0' )
	  /* do nothing */;

  cStart = cOldInput;
  cStart += strlen( cStart ) - 1;

  while( cStart >= cOldInput && ( *cStart == '0' || *cStart == ' ' || *cStart == 'r' || *cStart == 'n' || *cStart == '	' ) )
	cStart--;

  cStart++;
  *cStart = '0';

  while( *cStart != '0' )
  {
	if( *cStart == ';' )
	{
	  *cStart = '0';

	  break;
	}

	cStart++;
  }
}

Iata si un exemplu:

int main( )
{
  FILE *fFile = fopen( "myfile.txt", "a+" );
  char cLine[ 256 ];

  while( !feof( fFile ) )
  {
    fgets( cLine, 256, fFile );

    trim( cLine );

    printf( "%sn", cLine );
  }

  return 1;
}
