Re: Mis-feature?

Gentlepeople:

It seems wrong to me that there's no way to protect an object from
being violated by another object of the same type. Example code is
below. Is this a mis-feature / weakness of C++? Or is it desirable
in some way?

             Regards,

#include <iostream>
using namespace std;

class Arnold {

protected:

int age;

public:

Arnold(void) {age = 0;}
int GetAge(void) {return age;}
void SetAge(int newage) {age = newage;}
void SetAnotherObjectsAge(Arnold *otherObject, int newage)
{otherObject->age = newage;}

};

int main(int argc, char* argv[]) {
Arnold arn1;
Arnold arn2;

arn1.SetAge(10);
arn2.SetAnotherObjectsAge(&arn1, 12);
cout << "arn1's age is " << arn1.GetAge() << endl;

return 0;
}
