C$++\backslash \backslash$Step $2$: Implement Member Functions

Add four member functions to the Date class: getDay$(),$ getMonth$(),$ getYear$(),$ and set$($int d$,$ int m$,$ int y$).$ Ensure they are declared as public.Date$($int m$,$ int d$,$ int y$)//$another constructor with parameters$\{$ month $=$ m; day $=$ d; year $=$ y;$\}$int getDay$()\{$ return day;$\}$int getMonth$()\{$ return month;$\}$ int getYear$()\{$return $($year$)$;

$\}$

$//$assigns all values to private data members

void set$($int m$,$ int d$,$ int y$)\{$

month $=$ m;

day $=$ d;

year $=$ y;

$\}$

private:

int month;

int day;

int year;

$\}$;

Date yesterday$(4,18,2022)$; $//$call constructor with singleparameterDate tomorrow;tomorrow.set$(4,20,2022)$; $//$ sets $2$nd variable's membersDate $*$afterTomorrow $=$ new Date$(4,22,2022)$;cout $$ yesterday.getMonth yesterday.getDay yesterday.getYear$()$ endl;cout $$ today.getMonth today.getDay
