Contoh Aturcara C++

#include "iostream.h" // tukarkan tanda " kepada < dan > accordingly

class one_datum {
int data_store;
public:
void set(int in_value);
int get_value(void);
};


void one_datum::set(int in_value)
{

}


int one_datum::get_value(void)
{
return data_store;
}


main()
{
one_datum dog1, dog2, dog3;
int piggy;


dog1.set(12);
dog2.set(17);
dog3.set(-13);
piggy = 123;


// dog1.data_store = 115; This is illegal in C++
// dog2.data_store = 211; This is illegal in C++


cout << "The value of dog1 is " << dog1.get_value() << "\n";
cout << "The value of dog2 is " << dog2.get_value() << "\n";
cout << "The value of dog3 is " << dog3.get_value() << "\n";
cout << "The value of piggy is " << piggy << "\n";
}


// Result of execution
//
// The value of dog1 is 12
// The value of dog2 is 17
// The value of dog3 is -13
// The value of piggy is 123
