using namespace std;

class MyClass{
    public:
        MyClass(string mName);
        ~MyClass();
    private:
        string myName;
};

MyClass::MyClass(string mName){
    myName = mName;
    cout << "MyClass Constructor: " << myName << endl;
}

MyClass::~MyClass(){
    cout << "MyClass Destructor: " << myName << endl;
}

int main()
{
    cout << "Hello world!" << endl;
    MyClass myClass("MyClass 1");
    MyClass* myClassPtr = new MyClass("MyClass 2: created using new");
    delete myClassPtr;
    return 0;
