Explanation:

In the above program, we created a list and then add student names to the using Add() method.

IEnumerable<string> result = Students.Where(stu=>stu[0]=='S');

In the above code, where() method is used to select student according to a specified condition. Here we find the students whose name starts with 'S'.

Console.WriteLine("Student Names start with 'S':");
foreach (string name in result)
{
    Console.WriteLine(name);
}

Here we printed the select student name using the "foreach" on the console screen.
