关于基于Win32开发的模拟航空订票系统的问题
系统要求：
程序显示下列菜单选项：
Please type 1 for “smoking”
Please type 2 for “nonsmoking”
如果输入1，则程序指定吸烟舱位（座位1到5），如果输入2，则程序指定非吸烟舱位（座位6到10）。程序应输出一个登机牌，表示座位号和是否为吸烟舱位。程序不能再订已经订过的座位。吸烟舱位已满时，应该询问可否订非吸烟舱位；同样，非吸烟舱位已满时，应询问可否订吸烟舱位。如果同意，再相应订座，否则打印消息：“Next flight leaves in 3 hours”。
我的代码：
#include <string>
#include <iostream>
using namespace std;
int a[9] = {0};
int smoking_booked = 0;
int nonsmoking_booked = 0;
void smoking_book();
void nonsmoking_book();
void main(){
void system();
system();
}
void system(){
int choice;
cout < < "Welcome for using Universal Airline Ticket Booking System!\n "
< < "Please type 0 to exit the system.\n "
< < "Please type 1 for \ "smoking\ ".\n "
< < "Please type 2 for \ "nonsmoking\ ". " < < endl;
cin > > choice;
if (choice == 0) cout < < "Thank you for using, goodbye! " < < endl;
else if (choice == 1) smoking_book();
else if (choice == 2) nonsmoking_book();
else{
cout < < "Please input 0, 1 or 2!\n " < < endl;
system();
}
}
void smoking_book(){
int identify =0;
for (int i=0; i <5;){
if (a[i] == 1) i++;
else {
a[i] = 1;
cout < < "Congratulations! You 've book smoking seat successfully!\n "
< < "The seat NO. is " < < i + 1 < < ", Please enjoy your trip!\n "
< < endl;
identify = 1;
break;
}
}
if (identify == 0){
smoking_booked = 1;
if (nonsmoking_booked){
cout < < "We are so sorry that all of our tickets had sold out.\n "
< < "Please come and take our next flight, next flight leaves in 3 hours.\n "
< < "Thank you for using, See you next time!\n " < < endl;
system();
}
string decision;
cout < < "We are sorry to tell you that smoking seat had sold out.\n "
< < "Would you please change to nonsmoking seat?(Y/N) " < < endl;
cin > > decision;
if (decision == "Y ") nonsmoking_book();
else if (decision == "N "){
cout < < "System is now back to menu.\n " < < endl;
system();
}
else{
cout < < "Please input Y or N! " < < endl;
system();
}
}
system();
}
void nonsmoking_book(){
int identify =0;
for (int i=5; i <10;){
if (a[i] == 1) i++;
else {
a[i] = 1;

问题：在吸烟区座位满了以后程序提示是否转为非吸烟区，继续订非吸烟区的座位只能订到9号就提示座位已售完，不能订到10号座位；在非吸烟区座位订完后，程序直接输出座位已全部售完，不能转到吸烟区继续订座。在调试的时候我发现在第二种情况下尽管没调用smoking_book函数但是smoking_booked值仍然变成了1，请问这是什么原因？我觉得这就是问题的所在。我用Visual Studio2005以及Visual Studio 6调试均是这个问题。烦请各位大虾们花一点点宝贵的时间帮帮小弟~小弟新学的C++基础还不是很好~
[解决办法]
太长 先细看下
[解决办法]
int a[9] = {0};
＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝
int a[10] = {0};
