Proper way to copy a const* instance of MyGreatClass

So I have a class like so...

struct MyGreatClass
{
    int someInt;
    float someFloat;
};

which is inside another class...

struct MyEvenBetterClass
{
    const MyGreatClass* great;//do not, can not, must not change!

    MyEvenBetterClass(MyGreatClass* grr);//constructor...

};

which is constructed like this:

MyEvenBetterClass::MyEvenBetterClass(MyGreatClass* grr)
{
    great = grr;
}

using this code:

MyGreatClass instanceOfGreatClass;
instanceOfGreatClass.someInt = 8;
instanceOfGreatClass.someFloat = 4.5f;

MyEvenBetterClass instanceOfMyEvenBetterClass(&instanceOfGreatClass);

Right. Now say I want to copy the properties of the const* instance of MyGreatClass inside the MyEvenBetterClass...do I need to do something like this:

MyGreatClass::MyGreatClass(const* MyGreatClass mGC)//another constructor
{
    this->someInt = mGC->someInt;
    this->someFloat = mGC->someFloat;
    //etc.etc......
}

and then create an instance like so: MyGreatClass changableGreatClass(instanceOfMyEvenBetterClass.great);

Or is there a better way...?
