[C++][MODIFY][GIVEN CODE] the Falafel program to do the following:
1) Create a counter for each type of item sold (Falafels, Sodas, Extras). 2) Use a constant (const in C++, or #define in C) to define the tax rate. 3) When the 'T' key is pressed for the total, display the count and name for each item, the subtotal for all items, compute tax at 8.7%, display the amount of tax, and the final total for all items plus the tax. 4) Each display must show two digits past the decimal point for the subtotal, tax and total.
5) The program must process unexpected or illegal inputs. If the user enters a menu selection that is invalid, an error message must be displayed.
#include#include void DisplayMenu(); // display the menu using namespace std; int main(int argc, char* argv[]) { double total = 0.00; double price; char selection; do { DisplayMenu(); price = 0; cout << "Make your selection (FSXT): "; cin >> selection; switch ( toupper(selection) ) { case 'F': price = 5.15; break; case 'S': price = 2.24; break; case 'X': price = 1.57; break; case 'T': break; default: cout << "Illegal selection, try again." << endl; } total += price; } while (selection != 'T' && selection != 't'); cout << "The total is $" << total << endl; return 0; } void DisplayMenu() { cout << endl; // blank line before start of menu cout << "F = falafel $5.15" << endl; cout << "S = soda $2.24" << endl; cout << "X = extras $1.57" << endl; cout << "T = total" << endl; }
