I have errors in my c ++ code for the defining of my two of my program choices that I can't figure out. Please help.

#include #include using namespace std; // Function prototypes void showMenu(); void showFees(double, int); int main() { int choice; // To hold a menu choice int months; // To hold a number of months // Constants for the menu choices const int ADULT_CHOICE = 1, CHILD_CHOICE = 2, SENIOR_CHOICE = 3, DISABLEDVETERAN = 4, CLUBWORKER = 5, QUIT_CHOICE = 6; // Constants for membership rates const double ADULT = 40.0, SENIOR = 30.0, DISABLEDVETERAN = 1.0, CLUBWORKER = 5.0, CHILD = 20.0; // Set up numeric output formatting. cout << fixed << showpoint << setprecision(2); do { // Display the menu and get the user's choice. showMenu(); cin >> choice; // Validate the menu selection. while (choice < ADULT_CHOICE || choice > QUIT_CHOICE) { cout << "Please enter a valid menu choice: "; cin >> choice; } // If the user does not want to quit, proceed. if (choice != QUIT_CHOICE) { // Get the number of months. cout << "For how many months? "; cin >> months; // Display the membership fees. switch (choice) { case ADULT_CHOICE: showFees(ADULT, months); break; case CHILD_CHOICE: showFees(CHILD, months); break; case DISABLEDVETERAN_CHOICE: showFees(DISABLEDVETERAN, months); break; case CLUBWORKER_CHOICE: showFees(CLUBWORKER, months); break; case SENIOR_CHOICE: showFees(SENIOR, months); } } } while (choice != QUIT_CHOICE); return 0; } //***************************************************************** // Definition of function showMenu which displays the menu. * //***************************************************************** void showMenu() { cout << " \t\tHealth Club Membership Menu " << "1.
