    Simple File I/O

    It has been forever since I've programmed in C++, and I have sold off all of my programming reference books... I just need help in coding a routing to open a textfile to read 3 lines of 3 numbers, separated by spaces as such:

    10 20 30
    40 50 60
    70 80 90

    placing them into a 2d array... I'm having a hard time locating the procedures online as well... If someone could provide me with sample code or a link to an online source for such a task, it would be grateful.

    Code:
    int MyVar;
    ifstream ReadFile;
    
    ReadFile.open("MyFile.txt", ios::in | ios::nocreate);
    if(!ReadFile.fail())
    {
       //Reads one integer
       ReadFile >> Myvar;
    
       ReadFile.close();
    }

    There are hundreds of samples of file I/O on this board. Search the board with "ifstream".
