Class Celcius

Program ini dibuat menggunakan class untuk mencari celcius, se,oga bermanfaat bagi teman-teman. . . ^_^

#include <iostream.h>

#include <conio.h>

class Celcius {

friend ostream& operator<<(ostream&,const Celcius&);

friend istream& operator>>(istream&,Celcius&);

public:

  Celcius(double a=0):c(a){}

  double reamur() const;

  double fahrenheit() const;

  double kelvin() const;

private:

  double c;

};

ostream& operator<<(ostream& out,const Celcius& j){

  out << "Reamur     : " << j.reamur();

  out << "\nFahrenheit  : " << j.fahrenheit();

  out << "\nKelvin      : " << j.kelvin();

  return out;

}

istream& operator>>(istream& in,Celcius& j){

  cout << "Masukkan suhu dalam Celcius : "; in >> j.c;

  return in;

}

double Celcius::reamur()const{

   return (4/5.0*c);

}

double Celcius::fahrenheit()const{

   return (9/5.0*c+32);

}

double Celcius::kelvin()const{

   return (c+273);

}

void main(){

  Celcius j;

  cin >> j;

  cout << j;

  getch();

}
