help please

I want to ask about copy constructor.
is the line sum=huge1.add(huge2) will call the copy constructor?
int main()
{
HUGE_INT huge1(0),huge2(1), sum;

sum=huge1.add(huge2);

//are these two line also a copy constructor?
huge1.assign(huge2);
huge2.assign(sum);

return 0;

};

have you tried putting trace code in the copy constructor of the class to
see when it is called?
Are you aware of the rule of three?

We can't tell without seeing the definition of 'add()'.
Does it take its argument by reference?

int main()
{
HUGE_INT huge1(0),huge2(1), sum;

sum=huge1.add(huge2);

//are these two line also a copy constructor?
huge1.assign(huge2);
huge2.assign(sum);
