Create and run a hello world console app in Visual Studio, choosing a .NET six or seven target, and navigating project templates, solution explorer, and basic run workflow.

Examine the ranges of primitive data types in C sharp, including signed and unsigned integers, and explore how float, double, and char types define value limits and storage.

Practice declaring and using C# variables across int, float, double, char, and string types in a Visual Studio console project, displaying values with Console.WriteLine and exploring ranges and exponential notation.

Explore the char vs string distinction in C#, including Unicode, escape sequences, ASCII, and typecasting, and learn string concatenation with Hello World examples.

Explore typecasting in C#, covering widening (implicit) casting from int to double, narrowing (explicit) casting from double to int, defaults, ascii and unicode values, and data loss risks.

Learn how operators in C# act on operands to form expressions, including arithmetic, relational, logical, and assignment, with examples like a + b * c and string concatenation.

Learn to use logical operators in C# to evaluate boolean expressions, combine conditions with and, or, not, and apply these in if statements and loops.

Use ladder if else control statement in c sharp to evaluate multiple conditions in sequence with else if blocks; the first true condition executes, otherwise the final else handles fallback.

Explore how the switch statement in c sharp selects a code branch based on an expression using case, break, and default, and compare it with if-else for cleaner, faster code.

Practice using if-else and switch statements in C# to map a day value to Monday, Tuesday, or Wednesday, and handle an invalid date with a default case.

Explore how the enhanced switch in C# 8.0 enables switch expressions that return a result, mapping numbers to strings with a default underscore case; note this expands beyond actions.

Explore how methods in C# encapsulate tasks, with components (modifiers, return type, name, parameters, body), how to define and call custom and main methods, and distinguish non-parametric and parametric methods.

Create a C# program that reads student names and scores, computes a position via a ladder if-else in the position method, and prints each student's name with their position.

Learn how to implement a temperature conversion program in C# with two methods: calculate temperature and print result, converting between Celsius and Fahrenheit using standard formulas and user input.

Explore overload resolution priority in C# and how the compiler selects the best overload based on exact matches, conversions, and specificity to reduce errors.

Apply method overloading to calculate areas of rectangle, square, triangle, and circle. Implement four area methods in a shapes class using formulas, including pi 3.14.

practice string concatenation with method overloading by implementing two overloaded methods in C#: one concatenates two strings, the other uses a separator, and print results from main.

Learn to compute the Fibonacci sequence with recursion in C#, building a Fibonacci function and a print helper to display a user-specified number of terms.

Master exception handling in C# by using try, catch, finally, and throw to manage runtime errors such as divide by zero, ensuring robust input handling and resource cleanup.

Explore how debuggers and debugging work in C sharp using Visual Studio, including breakpoints, stepping, inspecting variables, memory and stack inspection, watch expressions, to identify syntax, runtime, and logical errors.

Explore loops in C sharp, including for, while, and do while, and learn how they enable repeated execution for data processing, automation, and building efficient algorithms in programming.

Master for loops by initializing, testing, and updating a counter, and printing iterations from 1 to 5; explore continue to skip, and break to stop at specific values like 8.

Explore the while loop in C sharp, initializing number to ten, testing number >= 1, decrementing with number--, and printing each value from ten down to one.

Build a C# even-odd finder using a while loop in Visual Studio, with a checkEvenOdd method and modulus logic to print numbers from 5 to 11 as even or odd.

Explore the do-while loop in C# and see how it executes at least once before condition checks, with examples for input validation, file reading, calculations, and game logic.

Write a C# program that sums integers from 21 down to 11 using a do while loop in Visual Studio. Print the final summation, 176.

Explore nested loops in C#, using an outer loop and an inner loop to print the multiplication table from 1 to 10, with tab-separated values and row breaks.

Develop a C# console exercise that prints a right-angle triangle of asterisks using nested loops and prompts for the number of rows.

Explore classes and objects in C# as blueprints for objects with state and behavior. Learn constructors and the new keyword to instantiate objects and call startup using dot notation.

Explore properties, fields, and methods in a C# class, detailing auto-implemented properties, custom getters and setters, and how they manage access to private fields.

Build a console library management system in C# using Visual Studio, featuring a library class with name, max books, book counts, add book, display books, and a destructor.

Practice finding the minimum and maximum numbers in an array using min and max methods, a foreach loop, and user input in C#.

Implement a C# console program that reverses an array in place using a two-pointer approach, prints the original and reversed arrays, and handles user input.

Compare the performance of ArrayList and LinkedList by building 1 million elements and retrieving the item at index 500,000, then report the retrieval times.

Practice checking a dictionary for a value by building an employee records app that collects id and name until the user types exit, stores them, and verifies a given name.

Explore stacks and queues in c sharp, covering fifo and lifo principles, enqueue and dequeue, push and pop, and how these structures relate to arrays and linked lists.

Create a hot potato game simulation in C# using a queue and a stack, implementing game flow, elimination, and winner display with user prompts.

Create a C# restaurant order tracker by building menu and order dictionaries, displaying the menu, taking validated orders, calculating the bill, and applying a 10% discount for totals over 100.

Build a gym fitness system in C# by defining a gym membership interface, an abstract gym member class, and a premium member that displays membership details.
