Latihan Fungsi di C++

#include <iostream.h>

#include <conio.h>

int data = 100;

void fungsi_satu ();

void fungsi_dua();

void main()

{

int data = 200;

fungsi_satu();

fungsi_dua();

cout << "Nilai data lokal main = "<<data <<endl; getch();

}

void fungsi_satu()

{

int data = 300;

cout << "Nilai data lokal satu = "<<data<<endl;

}

void fungsi_dua()

{

cout << "Nilai data eksternal = "<<data<<endl;

}
