Question

Alright, so I’m currently learning inheritance, and I’ve done something, this is the code:

class array
{
    int [] arr;
    public array(int[] arr)
    {
        this.arr = arr;
    }
    public int Biggest()
    {
        return arr.Max();
    }
    public int Min()
    {
        return arr.Min();
    }
    public int SumArr()
    {
        return arr.Sum();
    }
}
class array2 : array
{
    public array2(int [] arr):base(arr)
    {
    }
    public double Average()
    {
        return 
    }
}

Now, in the derived class I need to get the average of the array and I can’t do arr.Average()
The error says: Error 1 'ConsoleApplication1.array.arr' is inaccessible due to its protection level C:\Users\x\AppData\Local\Temporary Projects\ConsoleApplication1\Program.cs 35 20 ConsoleApplication1

Anyone can tell me what am I doing wrong?
Thanks for helpers!

Answer 1

arr is declared as private since you didn’t specify a visibility type. If you change it to protected, then your subclass array2 will be able to access it.

protected int [] arr;
