C++ print out objects error - c++

Question

I am getting stuck on print the object Meja1 and Meja2 into class Informasi.
How I can print the object Meja1.print_Meja(); and Meja2.print_Meja();
and please advice me how I can write my code into human readable coding style?
#include <iostream>
#include <string.h>
using namespace std;
class Inventaris {
private:
string Jenis;
string Warna;
string Keadaan;
public:
void setInventaris (string a, string u, string g)
{
Jenis=a;
Warna=u;
Keadaan=g;
}
string getJenis()
{
return Jenis;
}
string getWarna()
{
return Warna;
}
string getKeadaan()
{
return Keadaan;
}
void cetak ()
{
cout<<"Info Inventaris adalah :"<<endl;
cout<<"Jenis : "<<getJenis()<<endl;
cout<<"Warna : "<<getWarna()<<endl;
cout<<"Keadaan : "<<getKeadaan()<<endl;
}
};
class Kursi : public Inventaris {
public:
void print_Kursi(){
hitung++;
cout << "Informasi kursi adalah" <<endl;
cout<<"Jenis : "<<getJenis()<<endl;
cout<<"Warna : "<<getWarna()<<endl;
cout<<"Keadaan : "<<getKeadaan()<<endl;
}
static int hitung;
static getHitung()
{
return hitung;
}
};
class Meja : public Inventaris {
public:
void print_Meja(){
cout << "Informasi Meja adalah" <<endl;
cout<<"Jenis : "<<getJenis()<<endl;
cout<<"Warna : "<<getWarna()<<endl;
cout<<"Keadaan : "<<getKeadaan()<<endl;
hitung_meja++;
}
static int hitung_meja;
static getHitung_meja()
{
return hitung_meja;
}
};
class Informasi : public Meja, public Kursi {
public:
void print_info(){
cout << "Informasi" <<endl;
cout << "Jumlah Meja = " << Meja::getHitung_meja() << endl;
Meja1.print_Meja(); // how I print object Meja1 and Meja2
Meja2.print_Meja();
cout << "Jumlah Kursi = " << Kursi::getHitung() << endl;
}
};
int Kursi::hitung = 0;
int Meja::hitung_meja = 0;
int main() {
Kursi Kursi1;
Kursi1.setInventaris("Kursi goyang","Merah muda", "Bekas");
Kursi1.print_Kursi();
cout << endl;
Kursi Kursi2;
Kursi2.setInventaris("Kursi kakek","reyot", "Bekas");
Kursi2.print_Kursi();
cout << endl;
Meja Meja1;
Meja1.setInventaris("Meja Antik","Coklat tua","Bekas");
Meja1.print_Meja();
cout << endl;
Meja Meja2;
Meja2.setInventaris("Meja Coffee","Hijau Robek","Bekas");
Meja2.print_Meja();
cout << endl;
Informasi info;
info.print_info();
}

Answer 1

I fixed your code and I made Meja1 and Meja2 global declarations so they are accessible by main() and Informasi class.
#include <iostream>
#include <string>
using namespace std;
class Inventaris {
private:
string Jenis;
string Warna;
string Keadaan;
public:
void setInventaris(string a, string u, string g)
{
Jenis = a;
Warna = u;
Keadaan = g;
}
string getJenis()
{
return Jenis;
}
string getWarna()
{
return Warna;
}
string getKeadaan()
{
return Keadaan;
}
void cetak()
{
cout << "Info Inventaris adalah :" << endl;
cout << "Jenis : " << getJenis() << endl;
cout << "Warna : " << getWarna() << endl;
cout << "Keadaan : " << getKeadaan() << endl;
}
};
class Kursi : public Inventaris {
public:
void print_Kursi() {
hitung++;
cout << "Informasi kursi adalah" << endl;
cout << "Jenis : " << getJenis() << endl;
cout << "Warna : " << getWarna() << endl;
cout << "Keadaan : " << getKeadaan() << endl;
}
static int hitung;
static int getHitung() // <--- FIXED!
{
return hitung;
}
};
class Meja : public Inventaris {
public:
void print_Meja() {
cout << "Informasi Meja adalah" << endl;
cout << "Jenis : " << getJenis() << endl;
cout << "Warna : " << getWarna() << endl;
cout << "Keadaan : " << getKeadaan() << endl;
hitung_meja++;
}
static int hitung_meja;
static int getHitung_meja() // <--- FIXED!
{
return hitung_meja;
}
};
Meja Meja1; // <--- Global declaration accessible by main() and Informasi
Meja Meja2; // <--- Global declaration accessible by main() and Informasi
class Informasi : public Meja, public Kursi {
public:
void print_info() {
cout << "Informasi" << endl;
cout << "Jumlah Meja = " << Meja::getHitung_meja() << endl;
Meja1.print_Meja();
Meja2.print_Meja();
cout << "Jumlah Kursi = " << Kursi::getHitung() << endl;
}
};
int Kursi::hitung = 0;
int Meja::hitung_meja = 0;
int main() {
Kursi Kursi1;
Kursi1.setInventaris("Kursi goyang", "Merah muda", "Bekas");
Kursi1.print_Kursi();
cout << endl;
Kursi Kursi2;
Kursi2.setInventaris("Kursi kakek", "reyot", "Bekas");
Kursi2.print_Kursi();
cout << endl;
Meja1.setInventaris("Meja Antik", "Coklat tua", "Bekas");
Meja1.print_Meja();
cout << endl;
Meja2.setInventaris("Meja Coffee", "Hijau Robek", "Bekas");
Meja2.print_Meja();
cout << endl;
Informasi info;
info.print_info();
}
