I am studying Sam!s teach yourself cpp in one hour a day. On page 245 it explains move semantics briefly and says this code should trigger move constructor but I couldn't get it to work. What am I missing here?

#include <iostream>
#include <string.h>
using namespace std;
class MyString
{
private:
    char *buffer;

public:
    MyString(const char *initString) // constructor
    {
        buffer = NULL;
        cout << "Default constructor: creating new MyString" << endl;
        if (initString != NULL)
        {
            buffer = new char[strlen(initString)   1];
            strcpy(buffer, initString);
            cout << "buffer points to: 0x" << hex;
            cout << (unsigned int *)buffer << endl;
        }
    }
    MyString(const MyString &copySource) // Copy constructor
    {
        buffer = NULL;
        cout << "Copy constructor: copying from MyString" << endl;
        if (copySource.buffer != NULL)
        {
            // allocate own buffer
            buffer = new char[strlen(copySource.buffer)   1];
            // deep copy from the source into local buffer
            strcpy(buffer, copySource.buffer);
            cout << "buffer points to: 0x" << hex;
            cout << (unsigned int *)buffer << endl;
        }
    }

    MyString(MyString &&moveSource)
    {
        if (moveSource.buffer != NULL)
        {
            buffer = moveSource.buffer; // take ownership i.e. 'move'
            moveSource.buffer = NULL;
            // set the move source to NULL
        }
        std::cout << "moved" << std::endl;
    }

    // Destructor
    ~MyString()
    {
        cout << "Invoking destructor, clearing up" << endl;
        delete[] buffer;
    }
    int GetLength()
    {
        return strlen(buffer);
    }
    const char *GetString()
    {
        return buffer;
    }
};
void UseMyString(MyString str)
{
    cout << "String buffer in MyString is " << str.GetLength();
    cout << " characters long" << endl;
    cout << "buffer contains: " << str.GetString() << endl;
    return;
}

MyString Copy(MyString &source) // function
{
    MyString copyForReturn(source.GetString()); // create copy
    return copyForReturn;                       // return by value invokes copy constructor
}

int main()
{

    MyString sayHello("Hello World of C  ");
    MyString sayHelloAgain(Copy(sayHello)); // invokes 2x copy constructor before move constructor and must do one copy one move after move ctor but I couldn't observe that
    return 0;
}

Output:

Default constructor: creating new MyString
buffer points to: 0x0x556dd2cda2c0
Default constructor: creating new MyString
buffer points to: 0x0x556dd2cda2e0
Invoking destructor, clearing up
Invoking destructor, clearing up

No "moved" print in the output ?
