[英]Destructor in Constructor in c++?
我正在編寫一個票務預訂系統,我只是計划如何編寫它我面臨的問題有點棘手。 我的要求是:
現在我面臨的問題是,當超出限制時,我沒有得到不為乘客預訂機票的邏輯。 並自動將其預訂轉移到下一班車。
這是我迄今為止所做的代碼。
#include<iostream>
using namespace std;
class BUS {
int SOD = 6;
int EOD = 22;
int capacity=0;
int BUS_NO;
public:
BUS(int no) :BUS_NO(no) {
if (capacity == 100) {
cout << "Capacity is Full\n";
return;
}
else {
if (capacity != 100)
capacity++;
}
}
int bus_No() { return BUS_NO; }
void routes() {
cout << "=========================================\n";
cout << "1.Saddar " << "2.Marrir Chowk\n";
cout << "3.Liaquat Bagh " << "4.Committe Chowk\n";
cout << "5.waris Chowk " << "6.Chandni Chowk\n";
cout << "7.Rehman " << "8.6th Road\n";
cout << "9.Shamsabad " << "10.Faizabad\n";
cout << "11.Pothar " << "12.Khayan e Johar\n";
cout << "11.Pothar " << "12.Khayan e Johar\n";
cout << "13.Faiz Ahmad Road " << "14.Kashmir Highway\n";
cout << "15.Chaman " << "16.Ibn e Sina\n";
cout << "=========================================\n";
}
void reserveTicket() {
if (capacity != 100) capacity++;
else cout << "Wait for Next Bus plzz! This is full.\n";
}
};
class PASSENG {
};
在撰寫此答案時,我正在考慮我們有無限數量的可用總線。 現在我們 3 函數。 1.> ticket_book(int n)
=> 這個函數會為我們想要的乘客數量訂票。 如果乘客人數增加,那么它會自動預訂下一班可用巴士的車票。 2.> get_bus_capacity()
=> 該函數將返回當前總線中當前可用的座位。 3.> get_bus_number()
=> 該函數將返回當前總線編號。
#include<iostream>
using namespace std;
class BUS {
int SOD = 6;
int EOD = 22;
int capacity=0;
int BUS_NO = 1;
public:
void book_ticket(int n)
{
if(capacity + n <= 100)
{
capacity += n;
}
else
{
int cur_bus_seat = 100 - capacity;
int next_bus_seat = capacity + n - 100;
capacity = next_bus_seat;
BUS_NO += 1;
}
}
int get_bus_capacity()
{
return 100 - capacity;
}
int get_bus_no()
{
return BUS_NO;
}
void routes() {
cout << "=========================================\n";
cout << "1.Saddar " << "2.Marrir Chowk\n";
cout << "3.Liaquat Bagh " << "4.Committe Chowk\n";
cout << "5.waris Chowk " << "6.Chandni Chowk\n";
cout << "7.Rehman " << "8.6th Road\n";
cout << "9.Shamsabad " << "10.Faizabad\n";
cout << "11.Pothar " << "12.Khayan e Johar\n";
cout << "11.Pothar " << "12.Khayan e Johar\n";
cout << "13.Faiz Ahmad Road " << "14.Kashmir Highway\n";
cout << "15.Chaman " << "16.Ibn e Sina\n";
cout << "=========================================\n";
}
};
class PASSENG {
};
int main()
{
BUS bus;
int n;
while(1)
{
int choice;
cout<<"Enter Your Choice"<<"\n";
cout<<"Enter 1 to book ticket"<<"\n";
cout<<"Enter 2 to check number of seats"<<"\n";
cout<<"Enter 3 to check Bus No"<<"\n";
cin>>choice;
if(choice == 1)
{
cout<<"Enter the number of tickets to be booked";
cin>>n;
bus.book_ticket(n);
}
else if(choice == 2)
{
cout<<bus.get_bus_capacity()<<"\n";
}
else if(choice == 3)
{
cout<<bus.get_bus_no()<<"\n";
}
}
return 0;
}
