praktikum Minggu ke 3

1. Kelas turunan Bil_Float Mempunyai satu data member berTipe float...

#include "bilangan.h"

class Bil_float:public Bilangan{

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

public:

Bil_float(int aO=O, int bO=O, float cO=O.O):Bilangan (aO,bO),c(cO){}

protected:

float c;

};

2.Konstruktor dari Kelas Bil_float

Bil_float(int aO=O, int bO=O, float cO=O.O):Bilangan (aO,bO),c(cO){}


3.overloading inputnya

istream&operator(istream& in, Bil_float& x){

cout<<"nMasukkan bagian Integer a:";

in>>x.a;

cout<<"Masukkan Bagian Integer b:";

in>>x.b;

cout<<"Masukkan bagian float:";

cin>>x.c;

return in;

}

Overloading Outputnya

ostream&operator<<(ostream& out, const Bil_float& x){

out<<"bagian Integer a:"<<x.a<<endl;

out<<"bagian Integer b:"<<x.b<<endl;

out<<"bagian float c:"<<x.c<<endl;

return out;

}
