我想先感謝任何人和大家!我應該做的就是從文件中讀取數據(「inventory.txt」),並將這些數據傳遞給對象向量。所有的數據應該存儲在一個單獨的向量中,包括兩個類別信息,因此是班級車輛公共部分的班級經銷商的指針。這是txt文件中的數據;如何從文件讀取數據到對象

這是我的類定義:
class Dealer{ //deceleration of class Dealer
private: //private variables
string DealerName;
string DealerAddress;
public: //public members
//class mutators
void setName(string);
void setAddress(string);
//class accessors
string getName();
string getAddress();
Dealer(); // default constructor
Dealer(string, string); //overloaded constructor
};
class Vehicle{ //decleration of class vehicle
private: //private member variables
string VIN;
string Make;
string Model;
int Year;
double Price;
public: // public member variables and functions
Dealer *Dealerprt; //dealer class pointer
Vehicle(); //default constructor
Vehicle(string, string, string, int, double); //overloaded constructor
//class mutators
void setVIN(string); //sets member variable VIN to value in v
void setMake(string); //sets member variable Make to value in m
void setModel(string); //sets member variable Model to value in M
void setYear(int); //sets member variable Year to value in y
void setPrice(double); //sets member variable Price to value in p
//class accessors
string getVin(); //returns value stored in member variable VIN
string getMake(); //returns value stored in member variable Make
string getModel(); //returns value stored in member variable Model
int getYear(); //returns value stored in member variable Year
double getPrice(); //returns value stored in member variable Price
終於這是迄今爲止我已經寫的功能,並且是卡洛特型車輛的矢量的名字。另外我打算做的是創建一個臨時對象來讀取數據,然後將其傳遞給一個新的對象(導師的建議);
void readInv(vector<Vehicle>& carLot) {
Vehicle tempVehicle;
ifstream invFile;
invFile.open("inventory.txt");
cout << "the file is being read" << endl;
while(! invFile.eof()){
}
}
我知道這是有點長,但IM卡住,無法弄清楚如何正確地獲取數據到臨時對象。如果有一個更簡單的方式我打開它,但請我感謝任何幫助!非常感謝!
編輯我意味着矢量當我第一次發佈這個,我的意思是,我想直接從文件中讀入數據到臨時對象。
這可能是SO上最常見的問題之一。見例如。下面列出的問題之一----> – user463035818
下面是一條線索:std :: getline(invFile,line) – sithereal
