What is C++?
beginnerC++ is a general-purpose programming language created by Bjarne Stroustrup in 1979 as an extension of the C language.
Why Learn C++?
- High performance (used in game engines, browsers, operating systems)
- Foundational (understanding C++ makes other languages easier)
- Industry standard (used in finance, gaming, embedded systems, robotics)
- Direct memory control (unlike Python or Java)
Where is C++ Used?
| Domain | Examples |
|---|---|
| Game engines | Unreal Engine, Unity (partially) |
| Browsers | Chrome, Firefox |
| Operating systems | Windows, macOS parts |
| Databases | MongoDB, MySQL |
| Embedded systems | IoT devices, automotive |
| High-frequency trading | Financial systems |
C++ vs Other Languages
| Language | Key Traits |
|---|---|
| C++ | Fast, manual memory management, steep learning curve |
| Python | Easy to learn, slower, automatic memory management |
| Java | Portable, garbage collected, verbose syntax |
C++ Standard Versions
- C++98/03: Original standard
- C++11: Modern features (auto, lambda, smart pointers)
- C++14/17: Incremental improvements
- C++20/23: Latest features (concepts, ranges, coroutines)
Key takeaway: C++ is a high-performance language used in game engines, browsers, and embedded systems — understanding it makes other languages easier to learn.
Try it: Write a one-line C++ program that prints your name, then compile and run it.
