Expert Solution
Step 1

Solution: We are required to implement a class called "Weather" with one data member and to create a non-member method for class Weather to overload a relational operator.

 

A non-member function is a function that is defined outside the class but it is declared inside the class to correctly reference it.

 

Friend functions are non-member functions, as they are normal external functions with some special access privileges.

 

NOTE: As no programming language was specified I solved this in C++.

 

The C++ Code given below contains comments as well for a better insight into the implementation
