Do you mean you want you want the output to go in a file?

If so, you can get the general idea from this:

#include <fstream>
#include<iostream>
#include<string>

using namespace std;

class Appointment
{
public:

	Appointment();
	void addapointment();
	void display(ostream& out_str);
	void setDescription(const string&);
private:
	string name;
	string adress;
	string description;
};
 
Appointment::Appointment()
{
}

 void Appointment::addapointment()
{
	cout<<"enter the name"<<endl;
		getline(cin, name);
	cout<<"enter the adress"<<endl;
		getline(cin, adress);
	cout<<"enter the description"<<endl;
		getline(cin, description);

 }

 void Appointment::display(ostream& out_str)
 {
		 out_str<<"the appointment details are:"<< endl 
		 <<"name: "<<name<<endl
		 << "adress: "<<adress<<endl
		 <<"description: "<<description<<endl;
 }

 int main()
 {
	ofstream myfile("example.txt");

	 Appointment p;
	 cout<<"enter the details of appointment"<<endl;
	 p.addapointment();
	 p.display(cout);
	 p.display(myfile);
	 myfile.close();
	 return 0;
 }
