试图将结构对象传递给类头文件

Question

我正在尝试将我的项目从仅使用一个主文件转换为两个文件，方法是将所有结构和函数放入另一个头文件。但是我编译的时候好像解决了一个问题。我不知道..我现在到处都在编辑..它说'class ticket'在'void ticket::loadData(ticket::destination*)'和'中没有名为'b'的成员void ticket::Booking(ticket::clientInfo, ticket::destination*)'。我在学习 OOP 方面还是新手，并不真正了解这个概念。我有什么遗漏或做错了吗？

//my ticket.h
#include <iostream>
#include <fstream>
#include <string>
#include <cstring>
#include <iomanip>
using namespace std;
class ticket
{
  private:


  public:
     struct clientInfo 
     {
            string name,
                       matric,
            phoneNum;

     };
     struct destination 
     {
            string destinasi;
                string city[2];
            string code[2];
            float price;

     };

    ticket(){}; 
    void loadData(destination b[13] );
    void MainMenu(clientInfo a);
    void Booking(clientInfo a, destination b[13]);
    void printOut(clientInfo a, destination b[13], int y, string);    
};

void ticket::loadData(destination b[13])
{
  tiket hi;
  ifstream inFile;
  inFile.open("negeri3.txt");

  if(!inFile) { cout << "Error Loading File!";}
  else  
  { 
      for (int x=0; x < 12 ; x++)
      {  
         getline(inFile, hi.b[x].destinasi, ',');
         inFile.ignore();
         //cout <<hi.b[x].destinasi<<"\t";   //seem like if i try to output this, there is an output

         if(x<8)
         {
           for(int y=0; y<2; y++)
           {
             getline(inFile, hi.b[x].city[y], ','); inFile.ignore();
             //cout <<hi.b[x].cityr[y]<<"\n";
           } 
           for(int l=0; l<2; l++)
           {
             getline(inFile, hi.b[x].code[l], ','); inFile.ignore();
           } 
           inFile>>hi.b[x].price; inFile.ignore();
         }
         else if(x>=8)
         {
           getline(inFile, hi.b[x].city[0], ','); inFile.ignore();
           for(int y=0; y<2; y++)
           {
             getline(inFile, b[x].code[y], ','); inFile.ignore();
           } 
           inFile>>hi.b[x].price; inFile.ignore();
         }
      } 
  }

 inFile.close();    
}

void ticket::MainMenu(clientInfo a)

 tiket k;

 cout << "\n\t\t====== TICKET BUS SYSTEM ======";

 for (int y=0; y<12; y++)

     if(ngriMana == b[y].code[0] || ngriMana == b[y].code[1] )
        {
         cin.get();
         cin.get();
         printOut(a,b,y,date);
         hii = 1;
         }

  }

 if ( hii== 0)
 {
     for(int i=0; i<12; i++)
     {
              if( ngriMana != b[i].code[0] || ngriMana != b[i].code[1])
      {
        cout <<"\n\n\t\tYou have entered a wrong destination code! Please Try again";
        cin.get();
        cin.get();
           Booking(a,b);
      }
    }
   }
}

这是我的 main.cpp

#include <iostream>
#include <fstream>
#include <string>
#include <cstring>
#include <iomanip>
#include "tiket.h"

using namespace std;

int main()
{
    tiket ha;
    tiket::clientInfo a;
    tiket::destination b[13];

ha.loadData(b);
ha.MainMenu(a);
ha.Booking(a,b);

system("cls");
cout <<"\n\n\t\tTHANK YOU FOR USING OUR BUS SYSTEM :)\n";
cout <<"\t\tPLEASE REFER AND PRINT YOUR RESIT\n\t\t";
cout<<"\n\n\t\t";
system("PAUSE");
return 0;

Answer 1

首先，您应该修正代码中的拼写错误 (tiket - ticket)。然后你应该创建一个ticket.cpp 文件并将你的函数实现移到那里。当你将非内联函数的实现放在一个头文件中时，当你从多个 cpp 文件中包含它时，你会得到多个定义错误。

您还应该避免写信给cout 并避免在ticket 成员函数中获取用户输入。尝试将用户交互与数据存储分开。
