Introduction to C#

[Jessica Brown]

C# (pronounced "C-sharp") is a versatile, high-level programming language developed by Microsoft. It is widely used for building a range of applications, from desktop and web applications to games and mobile apps. C# combines the efficiency of modern programming features with the power of object-oriented programming.

What is C# Best Used For?

• Developing Windows desktop applications.
• Building web applications and APIs using ASP.NET.
• Creating games using the Unity game engine.
• Developing cross-platform mobile apps with tools like Xamarin.
• Writing enterprise-level applications for businesses.

Example C# Program

This program demonstrates variables, a loop, and output.

using System;

class Program
{
    static void Main()
    {
        // Declare variables
        string greeting = "Hello, C# Programmer!";
        int count = 5;

        // Display greeting
        Console.WriteLine(greeting);

        // Loop through numbers 1 to count
        for (int i = 1; i <= count; i++)
        {
            Console.WriteLine($"Iteration: {i}");
        }

        // Print completion message
        Console.WriteLine($"Loop completed! Total iterations: {count}");
    }
}

Explanation:

1. Variables: greeting is a string holding the welcome message, and count is an integer specifying the loop limit.
2. Loop: The for loop iterates from 1 to count, printing the current iteration with string interpolation ($).
3. Output: The program displays the greeting, each iteration, and a completion message.

Sample Output:

Hello, C# Programmer!
Iteration: 1
Iteration: 2
Iteration: 3
Iteration: 4
Iteration: 5
Loop completed! Total iterations: 5
