Carefully examine the code in Program 13-15, "Implementing the Class," in Section 13.13, "Focus on Problem Solving and Program Design: An OOP Case Study," in Ch. 13, "Introduction to Classes," of Starting Out With C++ From Control Structures Through Objects. Answer the following four questions in a Microsoft Word document:

On what line number(s) is the Account class instantiated?

Is the Account class declared in the code in Program 13-15? If not, where is the Account class declared and how do you know this?

On what line number(s) is the Account class constructor called?

On what line numbers are Account member functions called?

// This program demonstrates the Account class. #include #include #include #include "Account.h" using namespace std;

// Function prototypes void displayMenu(); void makeDeposit(Account &); void withdraw(Account &);

int main() { Account savings; // Savings account object char choice; // Menu selection

// Set numeric output formatting. cout << fixed << showpoint << setprecision(2);

do { // Display the menu and get a valid selection. displayMenu(); cin >> choice; while (toupper(choice) < 'A' || toupper(choice) > 'G') { cout << "Please make a choice in the range " << "of A through G:"; cin >> choice; } // Process the user's menu selection. switch(choice) { case 'a': case 'A': cout << "The current balance is $"; cout << savings.getBalance() << endl; break; case 'b': case 'B': cout << "There have been "; cout << savings.getTransactions() << " transactions. "; break; case 'c': case 'C': cout << "Interest earned for this period: $"; cout << savings.getInterest() << endl; break; case 'd': case 'D': makeDeposit(savings); break; case 'e': case 'E': withdraw(savings); break; case 'f': case 'F': savings.calcInterest(); cout << "Interest added. "; } } while (toupper(choice) != 'G');

return 0; }
