5. File Filter
A file filter reads an input file, transforms it in some way, and writes the results to an output
file. Write an abstract file filter class that defines a pure virtual function for transforming
a character. Create one subclass of your file filter class that performs encryption,
another that transforms a file to all uppercase, and another that creates an unchanged copy
of the original file.
The class should have a member function
void doFilter(ifstream &in, ofstream &out)
that is called to perform the actual filtering. The member function for transforming a single
character should have the prototype
char transform(char ch)
The encryption class should have a constructor that takes an integer as an argument and
uses it as the encrytion key.

-Main function must get input and output file names from the command line.

Second Part:

1) Using ROT13 Encrypt/Decrypt a file for both uppercase and lowercase alpha characters. Non-alpha characters shouldn't be changed.
