Is there another solution to this question besides the one that has been posted; the language is C++:

Write a program that reads an unspecified number of lines of text from STDIN, terminated with EOF. Each line will contain one single word with no whitespace. (so the input will consist of zero or more words.) Each word will be made up of only alphanumeric characters (so a-z, A-Z, 0-9) Your program should store all of the four length words and all of the five length words. Discard any inputs with fewer than four or more than five characters. The words should be stored in all lowercase. (HINT: )
