You cannot access the object's private variables outside its member
functions. This violates encapsulation. In the below function you are
trying to access the private variables of "loc" - an object of class
"location" inside the function "match" which is not the member
function of class location.

You should use "compare" inside ship::match() to compare two
locations.
