About This League

C# is a versatile object-oriented programming language developed by Microsoft, widely used for building Windows applications, web services, and games. This foundational league equips you with the essential C# syntax and programming logic required for entry-level software development roles. You will gain practical experience through hands-on exercises covering core language features.

What you will learn

Upon completing this league, you will be able to:

  • Write and execute your first C# program, understanding the role of the 'Main' method and basic output.
  • Declare and manipulate variables of fundamental data types like integers, decimals, booleans, characters, and strings.
  • Utilize arithmetic, assignment, comparison, and logical operators to build and evaluate expressions.
  • Implement conditional logic using 'if', 'else if', and 'switch' statements to control program flow.
  • Apply 'for', 'while', 'do-while', and 'foreach' loops for efficient repetition of code blocks.
  • Manage loop execution with 'break' and 'continue' statements for precise control over iterations.

What this league covers

ModuleWhat it covers
Your First C# Program: Hello, World!Introduction to C#, setting up your environment, writing 'Console.WriteLine', and understanding the 'Main' method.
Variables and Data Types: The Building BlocksDeclaring variables, working with integer, decimal, boolean, character, and string types, and performing type conversion.
Operators and Expressions: Doing the MathUsing arithmetic, assignment, comparison, logical, and increment/decrement operators, along with operator precedence.
Control Flow: Making DecisionsImplementing 'if', 'if-else', 'else-if', and 'switch' statements, including nested conditional structures.
Loops: Repeating ActionsEmploying 'for', 'while', 'do-while', and 'foreach' loops, and utilizing loop control statements like 'break' and 'continue'.

You are now equipped to begin learning C++ Programming.

Prerequisites

  • No prior experience needed — this league starts from the beginning.

Learning Objectives

  • Understand the basic syntax of C# including variable declaration, data types (int, string, bool), and assignment operators.
  • Create simple C# programs that utilize console input and output to interact with the user.
  • Implement conditional logic using if, else if, and else statements to control program flow based on specific conditions.
  • Develop programs that employ basic loops (for, while) to repeat actions a set number of times or until a condition is met.
  • Define and call simple methods (functions) to modularize code and promote reusability.
  • Explain the fundamental concepts of object-oriented programming in C#, including classes and objects.
