Question

Im a noob at this and was wondering why my array will output correctly within the while loop but once i cout the array outside of the while loop no information is displayed?
if you can explain it in beginner terms id really appreciate it.

   void Video::Read_Video()
{
    ifstream Din;
Din.open("Video.txt");
    if(!Din)
            cerr << "Could not open video.txt for reading." << endl;
    else
    {
        for(int i=0; i < Num_Of_Videos; i++)
        {
            while(Din.good())
            {
                getline(Din, Video_Array[i]);
                Num_Of_Videos++;
                cout << "Set_Video says these are the movies" << Video_Array[i] << endl;
            }
                                cout << "Set_Video says these are the movies" << Video_Array[i] << endl;

        }
        Num_Of_Videos = Num_Of_Videos-2;


    }
Din.close();

}

Your loop don’t make any sense. Inside the for loop, i is not incremented. So you keep reading into the same element of Video_Array. It’s not clear exactly what it is you’re trying to do, but the code as written doesn’t make much sense. Why do you have two loops?
