Create copy constructor in class date assume that dd- mm- yy as member

Answer 1

Is this what you're asking for?

public class date{
private int dd, // day
mm, // month
yy; // year

date(int dd, int mm, int yy){
this.dd = dd;
this.mm = mm;
this.yy = yy;
}
}

Answer 2

class date{
private
int _d;
int _m;
int _y;

//Default constructor
date(){
this._d = 1;
this._m = 1;
this._y = 1900;
}

//overloaded constructor
date(int d, int m, int y){
this._d = d;
this._m = m;
this._y = y;
}

//copy constructor
date(date &dt){
this._d = dt._d;
this._m = dt._m;
this._y = dt._y;
}

void show (){
cout<<this._d<<"-"<<this._m<<"-"<<this._y;
}

//overloaded constructor
void setDate(int d, int m, int y){
this._d = d;
this._m = m;
this._y = y;
}
};

int main (void){
date d1(14,3,2017); //overloaded constructor called implicitly
date d2=d1 //copy constructor called
d1.show();
cout<<"\n";
d2.show();

}
