how to make for statement correct?

malibumilk (9)
My for loop is not allowing two separate places for input. I am very new to C++ and do not speak english as my native language, and do not understand what my book is explaining!

    string title;

    int inventory = 3;
    
    //This is where I run into the problem, I cannot figure out how to initialize the whole array
    Author list[3] =

    cout << "\nGet users input:";
    
    getInfo(list,inventory);
    
    cout << "\nHere is the data after the users input:";
    
    showInfo(list,inventory);
    
    system("pause");
    return 0;
}

void showInfo(Author a[], int size)
{
    cout << fixed << showpoint << setprecision(2);
    
    for(int i = 0; i < size; i++)
    {
        cout << "The author: " << a[i].author << endl;
        
    for(int j = 0; j < size; j++)
    {
        cout << "\tThe title: " << a[i].books[j].title << ", the price: $" << a[i].books[j].price << endl;
        }
    }
}

void getInfo(Author a[], int size)
{
    for(int i = 0; i < size; i++)
    {
        cout << "\nEnter the author's name: ";
        cin >> a[i].author;
        
        if(a[i].author == "NONE")
            break;
        else
            
        for(int j = 0; j < size; j++)
            
        {
            cout << "\nEnter title " << j+1 << ": ";
           
            cin >> a[i].books[j].title;
            
            if(a[i].books[j].title == "NONE")
                    break;
            else
            cout << "\nEnter price " << j+1 << ": ";
            cin >>a[i].books[j].price;
            
            }
    }
}

Here is the output. The first bit is correct. When it ask for the title and I press the enter button, it print all the rest out. I want it to go for each step? And stop if I say "NONE".

Get users input:
Enter the author's name: Mr.ABC

Enter title 1: Intro to C++

Enter price 1: 
Enter title 2: 
Enter price 2:

Enter price 3: 
Enter the author's name:

//This is where I run into the problem, I cannot figure out how to initialize the whole array
    Author list[3] =
    {
        "NONE",
        {"NONE", 0},  //3 books for each author{"NONE", 0, "NONE", 0, "NONE", 0},


or you could initialize in the struct definition

struct BookInfo
{
    string title="NONE";
    double price=0;
};


Since there will probably be spaces in both the name and title, you can use getline for the strings. cin by itself won't get a whole string like "John Doe".

getline(cin, a[i].books[j].title);

http://www.cplusplus.com/reference/string/string/getline/

And add cin.ignore after the price input, so the newline character after the number entered is ignored.

cin >>a[i].books[j].price;
cin.ignore(1000, '\n');

Here is the data after the users input:The author: Mr.ABC
The title: Intro to C++, the price: $0.00
The title: Intro to Blac, the price: $0.00
The title: NONE, the price: $0.00
The author: Mr.DEF
The title: Intro to Wha, the price: $0.00
The title: , the price: $0.00
The title: Boop, the price: $0.00
The author: Mr.GHI
The title: Intro to C#, the price: $0.00
The title: NONE, the price: $0.00
The title: , the price: $0.00

it does not copy the prices!!

I think you're just missing the input line for the price before the cin.ignore line.

cin >>a[i].books[j].price;
cin.ignore(1000, '\n');
