Explanation

In the above program, we created a module Module1 that contains an Employee class and Main() function. The Employee class contains id, name, age, and salary data members.

The Main() function is the entry point for the program. In the Main() function, We created the list of Employees and then count the total employees using LINQ Count() extension method and then print the result on the console screen.
