C# Programming - Functions and Subroutines

1. Function definitions cannot be nested.
2. Functions can be called recursively.
3. If we do not return a value from a function then a value -1 gets returned.
4. To return the control from middle of a function exit function should be used.
5. Function calls can be nested.

    class SampleProgram

        static void Main(string[ ] args)
        {
            object[] o = new object[] {"1", 4.0, "India", 'B'};
            fun (o);
        }
        static void fun (params object[] obj)
        {
            for (int i = 0; i < obj.Length-1; i++)
            Console.Write(obj[i] + " ");
        }
    }
