如何创建文件和文件夹然后将该文件保存到文件夹中？

Question

我想创建一个文件夹，然后将我的文件保存到该文件夹​​中。我编写了自动创建文件的代码，我想将文件保存到文件夹中。我尝试过很多代码，但都没有。下面是我尝试过的最后一段代码，但它仍然不起作用：

void rooms() {
    Name rooms;
    Name rooms2;
    Name rooms3;
    Name staff;
    int b;
    char choicedo;
    string filename;
    string input;

    do
    {
        ofstream bilik2;
        bilik2.open("rooms2.txt", ios::out | ios::app);
        if(!bilik2)
        {
            cout<<"File Not Found!";
            exit(1);
        }
        if(bilik2 == NULL)
        {
            cout << "Error! Rooms is empty!";
            break;
        }

        ofstream bilik3;
        bilik3.open("rooms3.txt", ios::out | ios::app);
        if(!bilik3)
        {
            cout<<"File Not Found!";
            exit(1);
        }
        if(bilik3 == NULL)
        {
            cout << "Error! Rooms is empty!";
            break;
        }

        cout<<"1. Single Rooms "<<endl;
        cout<<"2. Family Rooms "<<endl;
        cout<<"3. Royal Rooms "<<endl;
        cout<<endl;
        cout<<"\nRooms type: ";
        cin >> b;
        system("cls");
        cout<<"Please fill in requirement information "<<endl;
        switch(b)
        {
            case 1:
            {
                cout<<"Room No: ";
                cin>>filename;
                input = filename;
                cin.ignore();
                //ofstream input("C:\\Users\\Dr. Akilah\\Desktop\\BLUE\\single room");
                mkdir("singleroom");
                ofstream outfile("singleroom");

                //system("mkdir singleroom");
                outfile.write(input.c_str(), input.size());
                input += ".txt";
                outfile.close();

                ifstream ifile(input.c_str());
                if(ifile)
                {
                    cout<<"Room is already exist."<<endl;
                    exit(1);
                }

                ofstream out(input.c_str());
                //out.open("C:/Users/Dr. Akilah/Desktop/BLUE/single room/ ", ios::out | ios::app);

                ofstream bilik;
                bilik.open(input.c_str(), ios::out | ios::app);
                cout<<endl;
                cout<<"Air Conditioner: ";
                cin.getline(rooms.airc, 20);
                cout<<"Date: ";
                cin.getline(rooms.date, 20);
                cout<<"Insert by: ";
                cin.getline(staff.first, 20);

                bilik<<"List of Single Rooms"<<endl;
                cout<<endl;
                bilik<<"------------------------------------------------------------"<<endl;

                bilik.close();
                break;
            }

            case 2:
            {
                cout<<endl;
                cout<<"Room no: ";
                cin>>rooms2.room;
                cin.ignore();

                cout<<"Insert by: ";
                cin.getline(staff.first, 20);
                break;
            }

            case 3:
            {
                cout<<endl;

编译此代码时：

出现此错误：

那么，我该如何解决这个错误呢？如何将文件保存到文件夹中？

Answer 1

std::ostream::put带有单个字符，而不是C字符串;为此，您应该使用std::ostream::write：

outfile.write(input.c_str(), input.size());
