/* Tuple class -> C# 4.0
 * Value Tuple, deconstruction and discards from c# 7.0 */

//Tuple Class
//1.Useful to return multiple values from a method or to pass multiple values to a method.
//2.Represents a set of values....no class
//3.Tuple stores only a set of values(of any data type..); but doesnt store property names..
//4.Maximum 8 values can be stored..But if you further want to increase it -go for nested tuples...
//5.It is meaning less to pass such big number of parameters to Tuple...go for classes instead

Console.WriteLine("-----Tuple Basic example-----------");
var tuple = new Tuple<int, string>(1, "hello");
Console.WriteLine(tuple.Item2);

//----------------------------------------------------------//
//Value Tuple --> c# 7.1
/*Simplified Syntax
1.No Item1..Item2 is needed unlike c#4.0
Older version of VS -> you need to install the package System.Value.Tuple but 
VS >=2019 its inbuilt...

/*Assigns elements of value tuples into individual local variables.
  Remove the reference variable...
