Explain why operator$$ must be overloaded as a non$-$member.

Part $2$

Overload the $+$ operator so that the following lines of code run in main:

More Details:

Define two functions. The prototypes will look like this:

Are they member or non$-$member functions? $($Notice how many arguments they have$)$

Both functions will create a temporary date and return it$.$

Think about reusing as much code as possible.

a$.$ For one implementation of operator $+,$ can you call the operator $++$ function?

b$.$ For the second implementation of operator$+,$ can you call the first operator $+$ function?

c$.$ Together these two functions should be no more that $10$ lines of code in the bodies. If you make it longer, you are working too hard.

Which of the two functions must be defined as a non$-$member? Why?
