C# Programming Mastery | Beginner to Advance Mastery Course

Learn how variables in C# act as placeholders and containers to store, update, and reuse data like names and ages, using int and string types and clear naming.

Explore data types in C#, including string, integer, float, double, char, and bool, and learn memory allocation, variable assignment, and basic console output.

Shows how to use comments in C# to document code and assist maintenance. Covers single-line // comments and multi-line /* ... */ comments for annotation and selective code suppression.

Learn how to collect user input in C# using the console, including name, age, and phone number, convert values with int and double, and print results with basic arithmetic.

Explore concatenation in c# by joining strings and numbers with the plus operator, print results with console.writeLine, and combine name and age into messages.

Learn how to work with DateTime in C# to format and print date and time, displaying year, month, day, hour, minute, and seconds in the console.

Explore arithmetic operators in C#, including plus, minus, multiplication, division, modulus, and increment and decrement, with integer and double variables and console output.

Explore how relational operators in C# compare values, including equal, not equal, less than, greater than, and their greater-than-or-equal and less-than-or-equal forms, with practical code examples.

Explore how to use logical operators in C# to validate conditions before execution, including and, or, and not operators, with practical x and y examples.

Master bitwise operators in C# by exploring and, or, xor, complements, and left and right shifts through practical console examples and binary calculations.

Explore assignment operators in C sharp programming, including plus equals, minus equals, division equals, modulus equals, and related comparisons with x, y, and z values.

Explore the if statement in C#, a decision-making construct that executes code when a condition is true and does nothing when it is false, with practical examples.

Explore how else if statements enhance decision making in C# by branching on values and printing corresponding messages for 10, 20, 30, or 40, and handling invalid input.

Discover how if-else statements in c# handle true and false conditions, using examples with x and y and console output to demonstrate branching decisions.

Master nested if statements in C sharp programming by learning a condition sits inside another, and both conditions must be met to execute code, illustrated with x=34 and y=9.

Learn how to implement a switch statement in C# to assign student grades, use cases with breaks and a default for invalid scores, and validate results.

Learn how to use the while loop in C# to execute code multiple times and print numbers from 1 to 20, demonstrating increment via console output.

Compare for loops with while loops by using a for statement to print numbers from 1 to 50, declaring the loop variable inside the parentheses and incrementing x.

Master the do while loop in c# by executing a block at least once and printing numbers from 1 to 10 with x initialized to 1 and incremented until ten.

Explore nested for loops in C# by building a simple prime-number checker that uses a loop inside a loop, modulus tests, and conditional breaks to print primes from 2 upward.

Discover how the break statement in C sharp programming exits a while loop when a condition is met, with console output showing numbers before the break.

Explore the continue statement in C# within a while loop, using x to skip values like 30 and print updated x values.

Explore how an infinite loop in C# programming runs without end, demonstrated with a for loop and semicolons. The lecture also covers for each, while, and do while loops.

Explore C# methods and functions, define and call methods outside main, and create a max num method to return the maximum of two integers.

Learn to define and call methods across multiple classes in C#, including a max finder with a maximum method that returns the larger of two integers.

Explore how to pass parameters by value in C#, as a void swap method shows two integers swap yet the original values stay unchanged, preparing you for the next lecture.

Learn how to pass parameters by reference in C# using ref, swapping two integers in place. See how w and z change before and after the swap.

Learn how to pass parameters by output in C# using the out keyword, with a practical example showing value changes before and after a method call.

Explore string objects in C# by declaring strings and chars, using arrays, and concatenating with string.Join, and applying date time formatting.

Master string comparison in C# using string equality and the string.Compare method, with length checks. Apply if statements and console output to show when first and last names match.

Explore substrings in C# by using the Contains method to check for words within a string, then conditionally print results with Console.WriteLine.

Learn how to extract a substring from a string in C#, counting characters including spaces, using a start index and length, and display results with Console.WriteLine.

Master joining two strings in C# by using string.Join on arrays, printing results with Console.WriteLine, and assembling phrases such as names and days of the week.

Demonstrates converting strings between lowercase and uppercase in C# using string methods, with console output showing the lowercase and uppercase results.

Discover how to define and use structs to model employee records in C#, including fields like name, position, salary, and age, and how to instantiate and print them.

Learn how to use methods within a structure to manage employee data, including defining private fields and public methods to set and print name, position, car, salary, and age.

Learn how to use the enum keyword to define a set of named integer constants, such as languages, with zero-based indexing and explicit value assignment.

Learn to work with classes in C#, create employee data models with name, age, position, and salary, and compute triangle area using base and height in separate classes.

Learn how inheritance works in C# by sharing properties between parent and child classes, handling public vs private access, and accessing inherited values such as 50.

Explore multiple inheritance by showing how a child class and a parent class can both inherit from A, with public and private properties and a get num method.

Master file input and output in C# by writing to and reading from a text file with System.IO, then displaying the contents on the console.

Learn to handle runtime errors in C# by using try-catch blocks to catch divide-by-zero and format exceptions, and customize user messages for numeric input.
