Solution

what are the mutators in the program? deposit() and withdraw() are the mutator here.
the accessors? getBalance() is the accessor in the class.
the local variables? initBal, owner, number, amtToTake, amtToAdd are all the local variables here.
the instant variables? The instance variables are: balance, name, and acctNum, s.
What are the parameters? The parameters for constructor are: initBal, owner, and number. The parameter for withdraw() is amtToTake. The parameter for deposit() is amtToAdd.
Which of the following contain comprise the state of an Account object?
Which of the following provide the behavior of an Account object?
Which of the following provide the behavior of an Account object?
What are the members. The member variables are: balance, name, and acctNum. The member functions are: Account(), withdraw(), deposit(), getBalance(), toString().
