For tests $5$ and $6,$ you will end up writing your own class, called TextCodec, make an instance of it$,$ call the Encode$()$ method $($described below$),$ and return the result of that method. The TextCodec class should be included within a new TextCodec.cpp file.

To create your TextCodec class, you will add the following access modifier, fields, constructor, and methods.

In addition, add the line #define TEXT$\_$CODEC at the top of TextCodec.cpp

For example:

#define TEXT$\_$CODEC

class TextCodec

$\{$

$//$ fields of this class

$//$ constructors of this class

$//$ methods of this class

$\}$

Your TextCodec class must have one member variable $($field$),$ which is:

a short int, which holds a numeric offset

You can name the field any name you want.

Your TextCodec class must have an overloaded constructor, which takes the offset variable that will be assigned to the field of the class:

TextCodec$($short int offset$)$
