Add a recursive function yearsFromRetirement() to the employeeType class as a member function. The function will return the number of years either before or after retirement, supposed to be 65, for a given employeeType instance. For example, if an employeeType instance has the age of 25, the function returns a message “It is 40 years before retirement”. If the employeeType instance has the age of 75, the function returns a message “It is 10 years after retirement (or simply -10 years before retirement)”.

I got the member function the age it's supposed to be I believe, but I'm not quite sure how to get the main function to accept the "age"
