Constructor and copy constructors - c++11

Question

I have started studying C++ after some years in C# and other languages. I am facing the class arguments (constructors, inheritance, copy etc) and I was trying to write a bad sample code. Below is a sample class (.h and .cpp):
#ifndef SAMPLE_H
#define SAMPLE_H
#include <iostream>
class Sample
{
public:
Sample();
//Sample(const Sample& s);
virtual ~Sample();
int *s_array;
protected:
private:
};
void print(const Sample *s);
#endif // SAMPLE_H
Sample::Sample()
{
std::cout<<"create sample\n";
s_array=new int[10];
std::cout<<"alloc memory 10 int array\n";
for(int i=0; i<10; ++i)
{
s_array[i]=i;
}
}
Sample::~Sample()
{
//dtor
std::cout<<"Dealloc memory 10 int array\n";
delete [] s_array;
std::cout<<"destroy sample\n";
}
void print(const Sample *s)
{
std::cout<<s<<" "<<s->s_array<<'\n';
for(int i=0; i<10; ++i)
{
std::cout<<s->s_array[i]<<" ";
}
std::cout<<"\n\n";
}
Then in main
#include <iostream>
#include "Sample.h"
using namespace std;
int main()
{
cout<<endl<<"Let's try the Copy const WRONG.... "<<endl;
Sample *s1=new Sample();
print(s1);
Sample s2(*s1);
cout<<endl<<"What is s2 ??? "<<endl;
print(&s2);
delete s1;
cout<<endl<<"What is s2 NOW after s1 delete??? "<<endl;
print(&s2);
return 0;
}
I wanted to test the dangers of NOT to use the copy constr and i expected to see after the deletion of s1 a totally 'dirty' array (i.e., 10 random values or even a crash)
This is the output I gain (Win 10 pro, IDE CodeBlock, GNU Gcc compiler):
Let's try the Copy const WRONG....
create sample
alloc memory 10 int array
0x1ba110 0x1b6e48
0 1 2 3 4 5 6 7 8 9
What is s2 ???
0x6efdf0 0x1b6e48
0 1 2 3 4 5 6 7 8 9
Dealloc memory 10 int array
destroy sample
What is s2 NOW after s1 delete???
0x6efdf0 0x1b6e48
1812296 1769664 2 3 4 5 6 7 8 9
Dealloc memory 10 int array
destroy sample
Why only the first two items of s_array are 'dirty' and the remaining 8 are good? Why the deletion of object s1 does not free the whole memory pointed by s2?
Thanx in advance
