*/

double get_balance();

(a) Which are the accessor function(s)?
(b) Which are the mutator function(s)?
(c) Create an object to represent a checking account with a starting balance of $1500.
(d) Provide a fragment of C++ code to perform this sequence of actions on the checking
account: deposit $100, print the balance, withdraw $250.

Solution

a) accessors

get_balance()

b) mutators

void deposit(double)

void withdraw(double)

c) BankAccount acc(1500.0);

d) acc.deposit(100.0)

acc.get_balance();

acc.withdraw(250.0)
