Q&A

Q1:	Why should I declare an object as const if it limits what I can do with it?
A1:	As a programmer, you want to enlist the compiler in helping you find bugs. One serious bug that is difficult to find is a function that changes an object in ways that aren't obvious to the calling function. Declaring an object const prevents such changes.
Q2:	Why should I bother to declare anything on the heap?
A2:	Objects on the heap persist after the return of a function. In addition, objects declared on the heap can be used to create complex data structures as explored in Hour 19, “Linked Lists.”
