How to filter products by type

[wtfwtf679]

void FTR(){
	string type;
	cout << "Please input the type of book:";
	cin >> type;
	ifstream file("test.txt");
    if(!file.is_open())
        cout << "Unable to open file\n";

}

I don't know how to write the code after cin is done!
The required .txt file(test.txt):
