}
public sample(string name) {
Console.WriteLine("This is our Parametrized Constructor");
Console.WriteLine("Name is :" + name);
}
public sample(string name, int age) {
Console.WriteLine("Name is " + name);
Console.WriteLine("Age is " + age);
}
}

static void Main(string[] args) {
sample s = new sample();
sample s1 = new sample("Nilesh");
sample s2 = new sample("24");
Console.ReadKey();
