berikut ini adalah program untuk menghitung luas dan keliling persegi panjang, menggunakan class:
here are source code :

#include <iostream>
#include <conio.h>
using namespace std;
class p_panjang {
  private:
      int p,l;
  public:
      int luas()
      {return (p*l);}
      void beri_nilai (int p1, int l1)
      {p=p1; l=l1;}
      int keliling()
      {return(2*(p+l));}
      void score_c(int p,int l)
      {p=7; l=10;}
};
void garis()
{
    int x;
    for(x=0;x<40;x++)
    cout<<"=";
    cout<<endl;
}
main() {
  cout<<"\n\tWELCOME IN RECTANGLE PROGRAM ";
  cout<<"\n\tALEX GUFRON";
  cout<<"\n\t2013-81-039\n";
  garis();
  p_panjang a,b,c;
  int x,y;
  cout<<"\n|Please Insert rectangle form |\n";
  garis();
  cout<<"\nInsert Long = ";
  cin>>x;
  garis();
  cout<<"\nInsert Width = ";
  cin>>y;
  garis();
  a.beri_nilai(x,y);
  b.beri_nilai(10,15);
  c.beri_nilai(7,10);
  system("cls");
  cout<<"\nTHE RESULT\n";
  garis();
  cout<<"\nLuas a = "<<a.luas();
  cout<<"\nLuas a = "<<a.keliling();
  cout<<"\n"<<endl;
  garis();
  cout<<"\nLuas b = "<<b.luas();
  cout<<"\nLuas b = "<<b.keliling();
  cout<<"\n"<<endl;
  garis();
  cout<<"\nLuas c = "<<c.luas();
  cout<<"\nLuas c = "<<c.keliling();
  cout<<"\n"<<endl;
  garis();
  cout<<"\n\tHAVE FUN With C++ ";
  getch();
