这段代码将被分成不同的功能,从它的外观来看,我可能会搞砸了。我所拥有的代码应该在int main之外的单独函数中,但我不确定这样做是否正确导致我对这个函数的新东西和我所拥有的书是如何显示如何的坏例子结构这个功能。

这是你正在寻找的吗?
说出&#39; getdays&#39;功能;它应该这样定义:
int getDays(){
int days;
cout << "Enter total of days you'll be staying: ";
cin >> days;
if (days < 0)cout << "Days cannot be less than 0 \n\n"<< "Enter total of days you'll be staying again: \n";
cin >> days;
return days;
}
并且在int main
中您可以拥有int days=getDays()
。
所以当你cout << days
时,你应该得到......无论用户输入什么。
希望它有所帮助!

以下实现仅针对“int getDays()”进行。您必须以这种方式修改所有这些方法。
#include <iostream>
#include <iomanip>
using namespace std;
//Function prototypes
struct HotelMenu
{
HotelMenu()
{
MILES = 0.27; //Expense per miles driven
PARKING = 6; //Allowed daily parking allowance
TAXI = 10; //Allowed daily taxi allowance
HOTEL = 90; //Allowed nightly hotel allowance
BKFST = 9; //Allowed daily breakfast allowance
LUNCH = 12; //Allowed daily lunch allowance
DINNER = 16; // ALlowed daily dinner allowance
}
int getDays();
double getDepartureTime();
double getArrivalTime();
double getAirfareFees();
double getRentalFees();
int getMileageFees();
double getParkingFees(int days);
double getTaxiFees(int days);
double getRegistrationFees();
double getHotelExpenses(int days);
double getBreakfastExpenses(int days, double dTime, double aTime);
double getLunchExpenses(int days, double dTime, double aTime);
double getDinnerExpenses(int days, double dTime, double aTime);
private:
//Global constants
const double MILES;
const int PARKING;
const int TAXI;
const int HOTEL;
const int BKFST;
const int LUNCH;
const int DINNER;
}
int HotelMenu::getDays()
{
int days;
cout << "Enter total of days you'll be staying: ";
cin >> days;
if (days < 0)
cout << "Days cannot be less than 0 \n\n"
<< "Enter total of days you'll be staying again: \n";
cin >> days;
return days;
}
double HotelMenu::getDepartureTime()
{
double dTime;
cout << "Enter your departure time: ";
cin >> dTime;
if (dTime < 0)
{
cout << "Time cannot be less than 0 \n"
<< "Enter departure time again: \n";
cin >> dTime;
}
else if (dTime > 24)
{
cout << "Time cannot exceed more than 24 hours \n"
<< "Enter departure time again: \n";
cin >> dTime;
}
return dTime;
}
int main()
{
//Variable Declaration
double grandTotal = 0, //Total expenses incurred
allowedTotal = 0, //Total allowable expenses for the trip
reimburseTotal = 0, //Excess that must be reimbursed, if any
savedTotal = 0, //Amount saved, if any
mealExpenses; //Total cost incurred for meals
// Create an instance of the structure
HotelMenu aInstance;
//Input & function processing
//Bullet 1
int days = aInstance.getDays();
//Bullet 2
double dTime = aInstance.getDepartureTime();
}
