Learn how visual cues in Visual Studio flag syntax errors and warnings in C# code. Explore underlines, nullable types, type mismatches, and effective debugging strategies to write correct, robust code.

Master debugging with breakpoints and variable watch, identify error types, and anticipate arithmetic and assignment operators in the next section.

Explore arithmetic operators in C#, including addition, subtraction, multiplication (asterisk), division (slash), and modulus (percent), and apply bodmas (order of operations) in real-world code.

this lecture demonstrates building a c# console app that prompts for two numbers, converts inputs to int, and computes sum, difference, product, quotient, and remainder with explicit casting when needed.

Learn how logic operators in C# compare values and return booleans, including >, <, ==, !=, and the or and and operators used in decision statements.

Summarizes a beginner C# console calculator workflow: prompts, input conversion, math and logic operations, and assignment operators, followed by committing and pushing enhancements on GitHub.

Explore if statements across languages and learn to evaluate conditions with true or false outcomes, using else blocks in a C# console app to grade and decide pass or fail.

Develop multi-branch decision logic with if, else if, and else in C#, ensuring non-overlapping conditions, printing grade-based results in a console app, and exploring the and operator in Visual Studio.

Learn how the C# ternary operator uses a condition, a question mark, and a colon to assign pass or fail in one line, and compare it with if statements.

Explore how switch statements compare to if statements, using case clauses and break, with a default catch-all; see a day-of-week example that prints outputs based on input.

Explore how variable scope and lifetime govern accessibility across code blocks, from global to local scope, and learn to apply dry principles and the ternary operator to manage variables efficiently.

Learn to build a functional calculator in a C# console app using if and switch statements to perform addition, subtraction, multiplication, and division from user input.

Explore the if, else if, switch, and ternary statements, understand their best-use scenarios, and learn to write readable, functional code with conditional logic.

Explore repetition statements by comparing counter-controlled and condition-controlled loops, including pre and post-test loops, and identify scenarios for loop usage with best practices to avoid pitfalls.

Explore why repetition statements matter by using loops to print text x times with a counter controlled for loop, and a condition control loop that runs until the user exits.

Explore counter-controlled for loops in C#, setting a lower bound, an upper bound, and an increment, then print Hello World ten times using zero-based counting and i++.

Explore while loops as condition controlled pretest loops, learn to set sensible conditions to avoid infinite loops, and practice with a counter, increments, and a negative-one exit to accumulate sums.

Explore core programming concepts in this lecture: increment vs accumulation, variable scope, iteration and nesting, and break and continue; and preview refactoring a calculator with loops for interactivity.

Write a console app that reads age, handles conversion errors with try...catch, and uses finally to print a thank you message, illustrating format and overflow exceptions.

Refactor the calculator to reduce repetition, introduce robust exception handling for user input, and handle divide by zero with specific catches, using continue and clear console flows.

Refactor the calculator app to reduce try catch blocks by wrapping the loop in a single try catch, handle divide by zero, and use a finally block to prompt user.

Improve calculator stability by wrapping input and division in a single try-catch within a loop, adding specific exception handling (format and overflow) and a finally block, and committing changes.

Master try catch and finally blocks, handling specific exceptions with tailored messages, deciding when to end or continue, and enhancing user experience through robust error reporting.
