Our password requirements are exactly the same as in the homework problem.

Minimum length of twelve characters

At least one UPPER CASE letter $($A$-$Z$)$

At least one lower case letter $($a$-$z$)$

At least one digit $(0-9)$

At least one "special" character $($printable$,$ but not alphanumeric$)$

No space characters

Write a program that reads a list of candidate passwords $($the number of passwords in the list is unknown$)$ and states the number of passwords that meet our qualifications. There is no need to use an array in this program; just read the passwords one line at a time $($hint$,$ hint$),$ test them, and keep track of the count of valid and invalid passwords.

I have a code, but I don't think it is reading the file line by line and I think its including space characters. How do I get the code to read line by line and make sure there are no space characters?
