Do I need prior experience?

No prior experience needed. Just need to know about `int` and `class` and `float` etc etc.

Nothing. `for` a is fine, then `b` is not fine. ```cpp #include sdfasdf sfasdff ```

C++ Fundamentals

Course Description

Welcome to the world of high-performance programming! This course is designed to take you from the foundational concepts of software development straight into the heart of C++, one of the most powerful and enduring programming languages ever created. Developed by Bjarne Stroustrup as an extension of the C language, C++ blends the raw speed and hardware-level control of low-level languages with the sophisticated abstraction of modern, object-oriented programming. Whether your goal is to build cutting-edge game engines, develop high-frequency trading applications, or program embedded systems, mastering C++ will give you a profound understanding of how software interacts with hardware.

Throughout this journey, you will move beyond just writing code that “works” to writing code that is highly optimized and robust. We will explore the core pillars of the language, beginning with basic syntax and memory management, before diving deep into Object-Oriented Programming (OOP) principles like inheritance, polymorphism, and encapsulation. You will also unlock the power of the Standard Template Library (STL), which provides a rich set of ready-to-use containers, iterators, and algorithms, allowing you to solve complex computational problems with elegance and efficiency.

What truly sets C++ apart—and makes this course so rewarding—is its philosophy of “zero-cost abstraction.” You will learn how to write high-level, expressive code without sacrificing runtime performance or bloated compiled binaries. By the end of this course, you won’t just know the syntax of C++; you will have developed a “programmer’s mindset,” equipped with the problem-solving skills and pointer discipline required to tackle engineering challenges at any scale. Get ready to control every byte and unleash the full potential of your machine!

Getting Started

What is C++ and Where It’s UsedⓘUnderstand what C++ is, where industry uses it, and why its performance and hardware control set it apart.

Anatomy of a C++ Program: main, Includes, NamespacesⓘUnderstand the structure of every C++ program: the main function, includes, and the std namespace.

How a C++ Program is Compiled and RunⓘUnderstand how C++ transforms source code into a running program through the preprocessor, compiler, and linker.

Comments, Whitespace, and Code Style BasicsⓘWrite more readable C++ code using comments, whitespace, and indentation to express intent and structure.

Print Three Words

Variables and Data Types

Variables and declarationsⓘLearn how to declare, initialize, and assign variables in C++, and write readable code with proper naming conventions.

Fundamental Types: int, double, char, boolⓘLearn the four core C++ value types, int, double, char, and bool, and what it means for a language to be statically typed.

Integer and Floating-Point Variants: Size, Sign, and PrecisionⓘLearn about C++ numeric types and choose the right integer or floating-point type to avoid overflow, precision loss, and subtle bugs.

Literals and constⓘLearn what literals are in C++, how their types are determined, and how to use const to declare unchangeable named values.

Type Deduction with autoⓘLearn how C++ uses auto to deduce variable types at compile time, keeping code concise without sacrificing static typing.

Checking Type Sizes and Limits in C++ (sizeof, <limits>)ⓘUse sizeof and numeric_limits in C++ to check a type’s exact size and value range on any platform.

Type Conversions and Casting in C++ⓘDistinguish implicit widening from narrowing conversions in C++ and cast explicitly with static_cast.

Tight Fit

Input and Output

Operators and Expressions

Arithmetic OperatorsⓘLearn how C++ arithmetic operators work, including integer truncation in division, the modulo operator, and operator precedence.

Assignment Operators and ExpressionsⓘMaster C++ compound assignment operators and learn how assignment itself is an expression, enabling chained assignments.

Comparison and Logical OperatorsⓘMaster C++ comparison and logical operators, understand how they produce bool values, and learn to combine them into precise expressions.

Bitwise OperatorsⓘManipulate individual bits in C++ using AND, OR, XOR, NOT, and shift operators with bitset output.

Increment and Decrement: Pre vs. PostⓘUse C++’s pre- and post-increment operators correctly and avoid the bugs that come from mixing them.
