trying to figure out the reason for memory loss any ideas would be helpful requirements should be done however i need a working file for turn in thanks for help.
leak seems to be around line 59-61 i think in demo.cpp

Problem Statement: (what you want the code to do)
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 encryption key.
Overall Plan (step-by-step how you want the code to make it happen):
0. create instances of subclasses
1. read data in from a file
2. Preform enctiption
3. set all to uppercase
4. transfer unchanged form input to output
5. output done.
etc.
Classes needed and Purpose (Input, Processing, Output):
