1. Change the getRegular and getBoGo functions to value-returning functions. Test the program appropriately.

#include

#include

using namespace std;

//function prototypes

void displayOptions ( );

void getRegular (int windows, double price, double &total);

void getBoGo (int windows, double price, double &total);

int main ( )

{

int option = 0;

int numOrdered = 0;

double winPrice = 0.0;

double totalOwed = 0.0;

cout << fixed << setprecision(2);

displayOptions ( );

cout << "Pricing option? ";

cin >> option;

if (option == 1 || option == 2)

{

cout << "Number of windows: ";

cin >> numOrdered;

cout << "Price per window: ";

cin >> winPrice;

if (option == 1)

getRegular (numOrdered, winPrice, totalOwed);

else

getBoGo (numOrdered, winPrice, totalOwed);

// end if

cout << "Total owed-----> $" << totalOwed << end1 << end1;

}

else

cout << "Invalid option" << end1;

// end if

return 0;

} // end of main function

//*****function definitions*****

void displayOptions ( )

{

cout << "Pricing options:" << end1;

cout << "1 Regular pricing" << end1;

cout << "2 BOGO pricing" << end1;

} //end displayOptions

void getRegular (int windows, double price, double &total)

{

total = windows * price;

} // end getRegular function

void getBoGo (int windows, double price, double &total)

{

total = (windows / 2 + windows % 2) * price;

} // end getBoGo function
