[英]Issue with C++ using getline and vector
我有一個問題,我正在使用getline從文件中讀取行,並使用stringstream來分隔不同的變量(使用逗號作為定界符)。 問題是變量的標准提示正確顯示了seatDes,但是使用向量我得到的名稱卻不是seatDes。 不知道為什么會這樣。
文件中的標准行:Jane Doe,04202013,602,1A
#include <iostream>
#include <fstream>
#include <string>
#include <sstream>
#include <vector>
#include <cstdlib>
#include "reservation.h"
int main(int argc, char **argv)
{
std::ifstream flightFile;
std::string name, date, seatDes, flightNum, line;
int error = 0, conFlightNum;
flightFile.open("reservations.txt");
if(!flightFile)
{
//returns a error value if there is a problem reading the file
error = 1;
return error;
}
else
{
//Start reading files and sticks them into a class object and sticks the object into the vector set
while (std::getline(flightFile, line))
{
std::istringstream ss(line);
std::getline(ss, name, ',');
std::getline(ss, date, ',');
std::getline(ss, flightNum, ',');
conFlightNum = atoi(flightNum.c_str());
ss >> seatDes;
reservation newRes(name, date, conFlightNum, seatDes);
std::cout << name << std::endl << date << std::endl << conFlightNum << std::endl << seatDes << std::endl;
std::cout << "Vector Component" << std::endl;
std::cout //<< newRes.getName() << std::endl << newRes.getDate() << std::endl << newRes.getFlightNum()
<< std::endl << newRes.getSeatDesg() << std::endl;
}
}
flightFile.close();
return 0;
}
Reservation.h文件
class reservation {
private:
std::string name, seatDesg, date;
int flightNum;
public:
//Default Constructor
reservation(){}
//Big Constructor
reservation(std::string name, std::string date, int flightNum, std::string seatDesg)
{
this->name = name;
this->seatDesg = name;
this->date = date;
this->flightNum = flightNum;
}
//Setters
void setName(std::string name)
{ this->name = name; }
void setFlightNum(int flightNum)
{ this->flightNum = flightNum; }
void setSeatDesg(std::string seatDesg)
{ this->seatDesg = seatDesg; }
void setDate(std::string date)
{ this->date = date; }
//Getters
std::string getName()
{ return name; }
std::string getSeatDesg()
{ return seatDesg; }
std::string getDate()
{ return date; }
int getFlightNum()
{ return flightNum; }
};
reservation(std::string name, std::string date, int flightNum, std::string seatDesg)
{
this->name = name;
this->seatDesg = name; // Here is your problem
this->date = date;
this->flightNum = flightNum;
}
應該
this->seatDesg = seatDesg;
