In the above program, we created a module Module1 that contains the Main() function. The Main() function is the entry point for the program.

In the Main() function, we created an integer array that contains 7 elements. Here, we used ElementAtOrDefault() LINQ extension method to print the elements of the array at the specified index, if the array element is not existing at the specified index then the default value will be printed on the console screen.
