Alright so Say I have a class with all its definition, bla bla bla...

template <class DT>
class Foo{
private:
    DT* _data;
    //other stuff;
public:
    Foo(DT* data){ _data = data }
    virtual ~Foo(){ delete _data }
    //other methods
};

And then I have in the main method:

int main(){
    int number = 12;

    Foo<anyRandomClass>* noPrimitiveDataObject = new Foo<anyRandomClass>(new anyRandomClass());
    Foo<int>* intObject = new Foo<int>(number);

    delete noPrimitiveDataObject; //Everything goes just fine.
    delete intObject; //It messes up here, I think because primitive data types such as int are allocated in a different way.

    return 0;
}

My question is: What could I do to have both delete statements in the main method work just fine?

P.S.: Although I have not actually compiled/tested this specific code, I have reviewed it extensively (as well as indented. You're welcome.), so if you find a mistake, please be nice. Thank you.
