C# Programming Fundamentals with Practical Examples

Explore object-oriented thinking in c sharp by examining classes, objects, data members, and member functions; compare inheritance, polymorphism, abstraction, and encapsulation with real-world analogies.

Explore how C# implements object oriented programming, covering classes, objects, data members, member functions, inheritance, polymorphism, abstraction, and encapsulation, with real world analogies and code reuse benefits.

Learn C# programming with a complete introduction to the modern object-oriented language, developed by Microsoft, featuring garbage collection and cross-platform support across Windows, Mac, Linux, and mobile devices.

Set up your C# environment by installing the dotnet core sdk, VS Code, and the C# extension, then verify with dotnet and run a console project.

Create a hello world program in c sharp using system, namespace, class, main method, and console.write line to display hello world.

Learn how to read user input and display output in C# by using console input/output functions, including Console.WriteLine, Console.Write, and Console.ReadLine, with string to int conversion and simple arithmetic.

Learn how to use single-line and multi-line comments in C sharp to explain code, leave notes, and help developers read your source, with VS code tips.

Explore variables and constants in c sharp, covering memory locations, data types, declaration versus initialization, naming rules, and why constants cannot be reassigned.

Explore data types in C sharp, including numeric types (int, long, float, double, decimal), boolean, character, and string, with examples of ranges, values, and basic usage.

Explore the operators in C#, including arithmetic, assignment, comparison, logical, bitwise, and conditional operators, with practical examples on operands, variables, and expressions.

Explore how the string data type stores text in C sharp, access characters by indexing, concatenate with + or concat, extract substrings with substring, and locate characters with index of.

Discover essential math functions in c#, such as abs, ceil, floor, round, max, min, pow, sqrt, and log, with practical vscode dotnet examples and radian degree conversions.

Master decision making in C sharp with if, if else, and switch statements, learn syntax, conditions, blocks, and how true or false conditions control program flow.

Explore how to use if, else, and else if in C# to handle multiple conditions and execute different blocks of code based on which condition is true.

Learn how the switch statement in C sharp evaluates a variable to run the matching case, using break and a default. See practical examples with day values like Monday.

Master the for loop in C# by learning initialization, condition, and increment/decrement, and see how to print numbers 0–9, 1–10, and 10–1 with practical examples.

Learn how the while loop repeats a code block while a condition true, compare it to the for loop, and generate numbers from 0 to 9 and 1 to 10.

Explore the do while loop in C# by comparing it with the while loop, and practice with practical examples that print numbers from 1 to 10 and 10 to 1.

Learn how to declare, initialize, and access arrays in C#, including zero-based indexing and contiguous memory storage. Explore syntax, memory location, and practical examples using for loops and console output.

Learn how methods in C sharp, equivalent to functions, organize code with public static and parameters, return values, and calling from main to implement tasks like login and search.

Explore function overloading in C#, defining multiple methods with the same name but different parameters. Create overloads with varying numbers and types of arguments to perform additions and display results.
