/*
 * LINQ(Language Integrated Query) is uniform query syntax in C# and VB.NET to retrieve data from different sources and formats.
 * With LINQ, a query is a first-class language construct, just like classes, methods, events.
 * It is simple, well-ordered and high-level language syntax to retrieve data from different sources and formats.
