C# Program to Implement Use of Indexers

This C# Program Implements Use of Indexers.Indexers allow instances of a class or struct to be indexed just like arrays. Indexers resemble properties except that their accessors take parameters.

Here is source code of the C# Program to Implement Use of Indexers. The C# program is successfully compiled and executed with Microsoft Visual Studio. The program output is also shown below.
