C# Overloading Test – 2

1. What will be the output of the following C# code?

class maths
{
    int i;
    public maths(int x)
    {
        i = x;
        Console.WriteLine(" hello: ");
    }
}
class maths1 : maths
{
    public  maths1(int x) :base(x)
    {
        Console.WriteLine("bye");
    }
}
class Program
{
    static void Main(string[] args)
    {
        maths1 k = new maths1(12);
        Console.ReadLine();
    }
}

2. When we call a constructor method among different given constructors. We match the suitable constructor by matching the name of constructor first, then the number and then the type of parameters to decide which constructor is to be overloaded. The process is also known as?

3. Correct statement about constructor overloading in C# is?
