using namespace std;


class Student
{
	string name;
	int ID;
	int age;
public:
	Student(string _name, int _ID, int _age)
	:name(_name),ID(_ID),age(_age){}
	string GetName() { return name; }
	int GetID() { return ID; }
	int GetAge() { return age; }

int main()
{
	Student arr[3] = { Student("Jack",12345,24),Student("Mary",98763,21),
					Student("John",24934,20)};
	ofstream of;
	of.open("student.txt",ofstream::out||ofstream::app);
	if (!of.is_open())
		cout << "File isn`t opened!";
	else
	{
		for (int i = 0; i < 3; i++)
		{
			of << arr[i].GetName()<<" " << arr[i].GetID()<<" "
				<< arr[i].GetAge() << endl;
		}
		of.close();
	}
	ifstream ifs("student.txt");
	ofstream ofnew;
	ofnew.open("studentCopy.txt", ofstream::out || ofstream::app);
	if (!ifs.is_open())
		cout << "File isn`t opened!";
	else
	{
		string line;
		while (getline(ifs, line, '\n'))
		{
			cout << line<<endl;
			ofnew << line<<endl;
		}
		ofnew.close();
		ifs.close();
