using namespace std;




int main()
{
	const string FILE_NAME_1="Laptop1.txt";
	const string FILE_NAME_2="Laptop2.txt";
	const string FILE_NAME_3="Laptop3.txt";


	//open the file "Laptop1.txt" 
	ifstream laptop1Ifstream(FILE_NAME_1);
	if(!laptop1Ifstream)
	{
		cerr << "Error: open file '"<<FILE_NAME_1<<"' not found.\n";
		return 1;
	}
	//open the file "Laptop2.txt" 
	ifstream laptop2Ifstream(FILE_NAME_2);
	if(!laptop2Ifstream)
	{
		cerr << "Error: open file '"<<FILE_NAME_2<<"' not found.\n";
		return 1;
	}
	string name;
	string RAM;
	string HDD;


	
	//read from the file "Laptop1.txt" 
	getline(laptop1Ifstream,name);
	getline(laptop1Ifstream,RAM);
	getline(laptop1Ifstream,HDD);
	laptop1Ifstream.close();


	cout<<"The file Laptop1.txt information:\n";
	cout<<"Name: "<<name<<"\n";
	cout<<"RAM: "<<RAM<<"\n";
	cout<<"HDD: "<<HDD<<"\n";




	string graphicCard;
	string OS;
	string processor;
	//read from the file "Laptop1.txt" 
	getline(laptop2Ifstream,graphicCard);
	getline(laptop2Ifstream,OS);
	getline(laptop2Ifstream,processor);
	cout<<"\nThe file Laptop2.txt information:\n";
	cout<<"Graphic card: "<<graphicCard<<"\n";
	cout<<"OS: "<<OS<<"\n";
	cout<<"Processor: "<<processor<<"\n\n";
	laptop2Ifstream.close();
	//Save to the file "Laptop3.txt"
	ofstream ofstreamLaptop3(FILE_NAME_3, ios::out);
	cout<<"\nThe file Laptop3.txt has been saved.\n";
	ofstreamLaptop3<<name<<"\n";
	ofstreamLaptop3<<RAM<<"\n";
	ofstreamLaptop3<<HDD<<"\n";
	ofstreamLaptop3<<graphicCard<<"\n";
	ofstreamLaptop3<<OS<<"\n";
	ofstreamLaptop3<<processor<<"\n";
	ofstreamLaptop3.close();
