The document contains multiple code samples written in C# that demonstrate various programming concepts, including handling user input, calculating totals, managing different types of scores, and working with arrays. It illustrates user interactions like entering order numbers, computing tuition costs, displaying web addresses, and finding median values for arrays. Each code snippet is followed by its expected output, showcasing the functional behavior of the programs.

1. Please follow the code and comments for description and outputs :
CODE :
using System;
