I found it very interesting. It crystalizes why so many people prefer
to write in C++ rather than Ada!

Aside from the verbosity of the Ada code (which is apparent even though
the C++ equivalents aren't written idiomatically), notice that in the
output code, it is necessary to repeat the types of the things being
output, even though the ompiler already knows it!

By the way, here's the C++ for your unimplemented third case -

#include <iostream>
#include <string>

using namespace std;

class SaveStuff
{
	string name;
	int save;
public:
	Save_Stuff(string n = string(), int s = 0) : name(n), save(s) { }
	void put(int x) { save = x; }
	int get() const { return save; }
};

int main()
{
	SaveStuff my_obj("My Object", 55);
	SaveStuff your_obj("Your Object", 55);

	my_obj.put(23);
	cout << "The value of my object is " << my_obj.get() << endl;

	your_obj.put(46);
	cout << "The value of your object is " << your_obj.get() << endl;
}
