The Ultimate C# Bootcamp: Build Modern Web & API Apps

Explore conditional statements in C# by implementing if-else logic and a switch example, controlling program flow and handling inputs such as voter eligibility and menu choices.

Explore the for, while, and do-while loops with practical C# examples. Show printing outcomes, counting 1 to 5, a countdown, and input validation for a positive number.

Explore break and continue statements in C# by demonstrating break to stop a loop after five iterations and continue to skip iterations, printing odd numbers.

Explore how methods are blocks of reusable code and how parameters pass data into them in C#. Create methods with and without parameters to display sums like ten and twenty.

Learn how classes serve as blueprints for objects in object oriented programming. See a practical person and car example with public fields and a display informations method.

Learn how encapsulation hides a bank account's private balance and exposes public methods like deposit and show balance to control interactions in C#.

Discover how interfaces and abstract classes work in C# by implementing a vehicle example and a circle that implements an interface with draw and get area methods using pi.

Learn to declare, initialize, and access one-dimensional and two-dimensional arrays in C#, use for-each loops to display matrix elements, and understand basic array concepts.

Explore lists in C#, using System.Collections.Generic to store dynamic collections, and learn to add, remove, and insert elements, then display updates with Console.WriteLine in a for each loop.

Explore dictionaries in c sharp, a generic key‑value collection for fast access, by creating a dictionary, adding employee IDs and names, retrieving values by key, and checking key existence.

Explore try-catch-finally blocks in C# to handle division by zero and format exceptions, demonstrate user input handling, and guarantee execution complete with a finally block.

Demonstrate throwing an argument exception for underage input (must be 18 or older) and handling it with a try-catch block, printing error and success messages to the console.

Build and handle custom exceptions in C#, creating an invalid input exception with a base class and using try-catch blocks to produce descriptive error messages.

Learn to create and run console applications in c#, build a simple grading program and a calculator using console input and output.

Build simple C# console apps by reading input from the console, greeting the user with string interpolation, and converting numeric input with Convert.ToInt32.

Learn how to write output to the console in C# using Console.Write and Console.WriteLine, including simple messages, variables, concatenation, and interpolation.

Explore how the common language runtime (clr) handles memory management automatically through garbage collection by creating a simple person class and allocating objects.

Discover how the .NET libraries and namespaces organize code with the system namespace and system.collections, use console.writeLine for output, and manage collections with lists in C#.
