Lab Exercise $-$ Overloading

Part $1$

Change the sameDay function into a overloaded $==$ operator. This will be a member function as demonstrated in the notes. Remember that you will want to compare the month, day, and year.

Add an overloaded $++$ operator $($as a member function, shown in the notes$)$

Just for fun, change the printDate function into an overloaded $$ operator as a non$-$member. The prototype in the $.$h will look like this:

ostreams operator$<mtext\; id="EditorElement\_1973517"></mtext><mi\; id="EditorElement\_1973518">(</mi>$ostreamb$,$ const Dates$)$;

The function itself will look like this:

Ostreams operator$<mtext\; id="EditorElement\_1973602"></mtext><mi\; id="EditorElement\_1973603">(</mi>$ostreams os$,$ const Dates myDate$)$

os $$ "Date $1$s: $"$ myDate. getMonth$()$

$=l^{\text{'}\text{'}}$ myDate.getDay $()$

$\frac{?}{?}="$ myDate. getYear$()$ endl;

return os;

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:

Date operatort $($const Dates, int$)$;

Date operatort $($int$,$ const Dates$)$;

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 operatort, can you call the operator$+$t function?

b$.$ For the second implementation of operatort, 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?
