Course Content
1. Data Types and Type Safety
1.1 One Line, One Variable: The Secret to Cleaner C++
Why declaring multiple variables in a single line quietly damages readability and increases bug risk. Learn the professional standard used in production C++ codebases.
1.2 Stop Declaring Variables Too Early!
Why early declarations make code harder to reason about and easier to misuse. Scope is not just a language feature — it’s a safety tool.
1.3 One Variable, One Job: Avoiding Common Pitfalls
Variables should express intent, not convenience. Learn how multi-purpose variables silently break logic and confuse future readers.
1.4 Avoiding Variable Shadowing
Shadowed variables compile cleanly — and cause real bugs. Learn how to spot and eliminate shadowing before it reaches production.
1.5 Scope Matters: The Secret to Cleaner, Safer C++ Code
How tight scopes reduce cognitive load, prevent misuse, and make your code self-documenting.
2. Variable Management and Scope
2.1 The Hidden Danger of Unsigned Integers Why unsigned types are one of the most misunderstood and misused features in C++. Real-world bugs, real consequences.
2.2 Fixing Literal Suffix Ambiguity How numeric literals can silently change types and behavior — and how professionals make intent explicit.
3. Control Structures and Loops
3.1 For vs While: A Simple Choice That Prevents Big Bugs
Choosing the right loop is not style — it’s correctness.
3.2 Switch Statements vs. If-Else Chains
When switch improves clarity — and when it becomes a maintenance nightmare.
3.3 Keep Your For Loops Simple and Safe
Complex loop headers hide logic and increase error rates. Learn the clean, readable alternative.
3.4 Preventing Infinite Loops: The Floating-Point Mistake
Why floating-point comparisons in loops are a ticking time bomb.
3.5 Why Range-Based Loops Should Be Your Default
Modern C++ gives you safer loops — but only if you use them correctly.
3.6 Keep It Small: Why Loop Variables Belong Inside the Loop
Reducing scope is one of the cheapest safety improvements you can make.
4. Operators, Conditions, and Expressions
4.1 Why Parentheses Improve Readability
Even when precedence is correct, clarity is not guaranteed.
4.2 Why the Comma Operator Is a Trap in C++
A legal operator that almost never belongs in clean C++ code.
4.3 Why Explicit Conditions Matter in C++
Implicit truthiness leads to implicit bugs.
4.4 Always Make Your Conditions Explicit
Readable conditions reduce mental overhead and prevent misinterpretation.
4.5 The Hidden Dangers of Logical Operators
Short-circuiting, side effects, and readability traps.
4.6 Simplify Your Conditions: Less is More in C++
Complex conditions are a design smell. Learn how to refactor them cleanly.
6. Introduction to Smart Pointers (unique_ptr & shared_ptr)
6.1 Smart Pointers to the Rescue: Modern Memory Management in C++
Why raw ownership is a liability — and how modern C++ fixes it.
6.2 The Hidden Danger in Your std::shared_ptr Usage
shared_ptr is powerful — and extremely easy to misuse.
7. RAII and Resource Management
7.1 Destructor Myths in C++: Do You Really Need One?
Most destructors you see should not exist.
7.2 Stop Using goto for Cleanup! Use RAII Instead
How RAII replaces error-prone manual cleanup patterns.

When a function should not be a class member.
