In c++: Assume we already have == and < operators overloaded for a class. Can you complete the other comparators based on the existing ones?

--------------

Can anyone help me with this question?

Here's a similar question that I've done before: Assume the += operator and unary negation has been overloaded correctly for MyClass. Write code to implement the subtraction operator ( - ) that would be found in MyClass.cpp., and the answer for this question is

MyClass MyClass:: operator-(MyClass rhs){

return (*this += (-rhs)); }

So I'm wondering if this question ask us to use only == and < to create the other comparators? How?
