for example : some websites ask for a password including some specific characters , like one letter, one ( /,%,*,),(,...) so my purpose is to create a program .first ask for username , then password , then check them , if they don't match with stored (username and password ) , make them register and during that , store "username " and "password" but "password must be including 1 letter , 1 sign , and less than 10 length , more than 4 . l don't know how to do it.as l tried many things but  l got error . l hope it would be more explaintory as my English is not good enough.thanks for any advice in advance

best regards.
