What is C++? · C++

Ch 1 · Introduction to Programming & C++ — card 2 of 2.

C++ extends the C language with powerful new tools — most importantly, object-oriented programming and a huge library of ready-made data structures. It keeps C's famous speed and low-level control, while adding features that make large, complex programs easier to organise. This blend of raw performance and high-level features is why C++ powers so much demanding software.

Why C++ is worth learning:

• ✅ Blazing fast — used where performance is critical
• ✅ Object-oriented — great for organising big projects
• ✅ Comes with the Standard Template Library (STL) full of ready tools
• ✅ Gives you both high-level features and low-level control

Where C++ is used in the real world:

• 🎮 Game engines (Unreal Engine) and AAA games
• 🌐 Web browsers and high-performance servers
• 💹 Trading systems where every microsecond counts
• 🤖 Robotics, graphics, and operating systems
