PROGRAM MENGHITUNG SEMUA LUAS BANGUN DENGAN CLASS

PROGRAM MENGHITUNG SEMUA LUAS BANGUN DENGAN CLASS

ya ini program di buat dalam keadaan tergesa-gesa. ,hehehe . , maklum lagi di kejar waktu. ,soalnya siang harus di presentasikan jadinya pagi-pagi jam 8 harus berkutat dengan dev. ,saya memakai dev C++ untuk membuat program ini. ,hehe.

#include
#include

using namespace std;

class Luas

{
protected : int panjang, lebar, sisi,jari,alas,tinggi,pilihan;
char k;


public : void nilai(int a, int b, int c, int r, int x , int y)

{ panjang=a; lebar=b; sisi=c; jari=r; alas=x; tinggi=y; }
};

class Persegipanjang : public Luas

{
public : int area(void)
{ return(panjang*lebar); }
};

class Segitiga : public Luas

{

public : int area(void)
{ return(panjang*lebar/2); }
};

class Persegi : public Luas

{
public : int area(void)
{ return(sisi*sisi); }
};


class Lingkaran : public Luas

{
public : int area(void)
{ return(3.14*jari*jari); }
};

class Jajargenjang : public Luas

{
public : int area(void)
{ return(alas*tinggi); }
};

class Bola : public Luas

{
public : int area(void)
{ return(4*3.14*jari*jari); }
};

int main()

{
int a,b,c,r,x,y;


Persegipanjang ppg;
