Program C++ mengalikan 2 bilangan integer

Algoritma :

Deskripsi

a,b              : integer

hasil             : integer

Deklarasi

hasil <= a * b

write(hasil)

Berikut programnya :

#include <iostream>

#include <conio.h>

class Perkalian {

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

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

     

public :

       Perkalian();

       void hitung_perkaliannya(){ hasil = (a*b);}     

private :

       int a,b;

       int hasil;  

};

Perkalian::Perkalian(){

       cout<<"Program mengalikan 2 integer \n";

       cout<<"Selamat berkarya \n";       

}

istream& operator >> (istream& in, Perkalian& masukan){

         cout<<"Masukan nilai a : ";

         in>>masukan.a;

         cout<<"Masukan nilai b : ";

         in>>masukan.b;

         return in;

}

ostream& operator << (ostream& out, const Perkalian& keluaran){

         out<<" Nilai a : "<< keluaran.a << endl;

         out<<" Nilai b : "<< keluaran.b << endl;

         out<<" Hasil kali integer di atas : "<< keluaran.hasil << endl;

         return out;

}

main(){     

         Perkalian X;

         cin>>X;

         X.hitung_perkaliannya();

         cout<<X;

        

    getch ();

    return 0;

}

Explanation:
Program over the program to find the product of two integers. Which uses variables a, b and results. The program will perform the multiplication with a predetermined formula. With input from the keyboard and produce output that has been made ​​according to the program.
