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 find the average of employees salary using LINQ query and then print the result on the console screen.
