Question:
Derive a class from long_int class and add a member function "multiply" in the derived class to multiply two long_ints using the add member function already defined.
multiply should work like this 2*3 = 2+2+2 (adding 2, 3 times).
One you are done defining the multiply function, overload * operator to multiply two long_ints.
