Question

我试图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到另一个头文件中。但似乎我在编译时已经克服了一个问题。我不知道......我现在就在这里和那里进行编辑......它说的是“等级票”＃34;没有名为＆＃39; b＆＃39; in＆＃39; void ticket :: loadData（ticket :: destination *）＆＃39;和＆＃39;无效票据::预订（ticket :: clientInfo，ticket :: destination *）＆＃39;。我在学习OOP方面还很陌生，并且不太了解这个概念。有什么我遗漏或做错了吗？

//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++)
           {

           } 
           inFile>>hi.b[x].price; inFile.ignore();
         }
         else if(x>=8)
         {

           inFile>>hi.b[x].price; inFile.ignore();
         }
      } 
  }

 inFile.close();

void ticket::MainMenu(clientInfo a)

        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，您应该修复代码中的拼写错误（tiket - ticket）。然后你应该创建一个ticket.cpp文件并在那里移动你的函数实现。当您将非内联函数的实现放在头文件中时，如果从多个cpp文件中包含它，则会出现多个定义错误。

您还应该避免写入cout并在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。

尝试将struct对象传递给类头文件
