使用函数从文件输出

Question

the title says it all

This is my code: I have a class called House, where i define the values.

class HOUSE
{
public:
    int id;
    string 1;
    string 2;
    string 3;
    int an;


};

template<class Type>
class table
{
public:

    vector<Type> V;
    //double inceput;
    //double sfirsit;
    //int comparatii;
    //int interschimbari;   
public:
    table();
    void print();
    void liniar();
};

template<class Type>
table<Type>::table()
{
    ifstream file("file.txt");
    ifstream file1("file1.txt");

    if (file.fail() || file1.fail())
    {
        cerr << "Eroare la deschiderea fisierului!" << endl;
        _getch();
        exit(1);
    }

    HOUSE* value = new HOUSE;

while (!file.eof() || file1.fail())
{
    file >> value->id;
    file >> value->tara;
    file >> value->brand;
    file >> value->culoare;
    file >> value->an;

    this->V.push_back(*value);
}


file.close();

}

The print function for the values

template<class Type>
void table<Type>::print()
{

    cout << endl << setw(50) << "AFISAREA DATELOR" << endl;
    cout << setw(5) << "Id" << setw(15) << "1" << setw(20) << "2" << setw(17) << "3" << setw(20) << "an" << endl << endl;
    for (int i = 0; i < this->V.size(); i++)
    {
        cout << setw(5) << this->V.at(i).id << setw(15)
            << this->V.at(i).1<< setw(17)
            << this->V.at(i).2<< setw(17)
            << this->V.at(i).3<< setw(25)
            << this->V.at(i).an << endl;
    }
    cout << endl << "Dimensiunea tabelului  n= " << V.size() << endl;

}


{
        file >> value->id;
        file >> value->1;
        file >> value->2;
        file >> value->3;
        file >> value->an;

        this->V.push_back(*value);
    }


    file.close();

}

in main

int main() {

    table<MOBILE>* file = new table<MOBILE>();
    table<MOBILE>* file1 = new table<MOBILE>();

 file ->print();    
 file1 ->print();

This is full code as requested. Need make it somehow print the data from file1 and file2 . thx

The problem is idk if called right. Because file ->print();
file1 ->print(); both print data from the file only There are no errors at all

There's lots and lots wrong with your code. but I'm going to ignore that and just answer what I think is your actual question.

You want two table objects, one of which reads from file.txt and the other reads from file1.txt . To do that you should pass the file name into the table::table constructor, so it knows which file to read from. Like this

template<class Type>
class table
{
    ...
public:
    table(const char* filename); // constructor takes filename parameter
    ...
};


template<class Type>
table<Type>::table(const char* filename)
{
    ifstream file(filename); // open filename
    if (file.fail())
...


int main() {

    table<MOBILE>* file = new table<MOBILE>("file.txt"); // read from file.txt
    table<MOBILE>* file1 = new table<MOBILE>("file1.txt"); // read from file1.txt

    file ->print();    
    file1 ->print();
}
