C++ basics

C++ is a general-purpose programming language known for performance, control over memory, and strong support for systems programming. Even today, it remains one of the most important languages in robotics, game engines, real-time systems, embedded software, and high-performance applications.

Why C++ is still relevant

  • Excellent runtime performance
  • Fine-grained control over memory and resources
  • Strong support for object-oriented and generic programming
  • Huge adoption in performance-sensitive domains

Where C++ is commonly used

  • Robotics and ROS
  • Autonomous driving software stacks
  • Game engines
  • Operating systems and embedded software
  • High-frequency and low-latency systems

A simple example

#include <iostream>
#include <vector>

int main() {
    std::vector<int> values = {1, 2, 3, 4};
    for (int v : values) {
        std::cout << v << std::endl;
    }
    return 0;
}

Why learning C++ helps engineers

C++ teaches important ideas about memory, object lifetime, abstraction cost, compilation, and performance trade-offs. Even if you later spend more time in Python, knowing C++ often makes you a stronger engineer.

Final thoughts

C++ is not always the easiest language to learn, but it is one of the most valuable languages if you want to build fast and robust software close to the system level.
