hahaha, I have really been stuck...u said the shift operators can be used in Checksums, hashing, encryption...is there anywhere I can actually get to see such examples? I want to learn more, I feel it is important to master these. In the second example, you shifted 15 bits to the right of the value of $? and 8 and bits as well, but you have &ed that while for the last $? of $exit_code, you only &ed...what does & do in this context..only in this context...
