sortlines
Write a program called sortlines that reads one line at a time from the standard input, and outputs the sequence of words in each line sorted in lexicographical order. A word is a (maximal) contiguous sequence of alphabetic characters as defined by the isalpha library function. The output sequence for each line should be printed on a single line with each word separated by one space. An input line is guaranteed to be at most 1000 characters.
