C++ Beginner

From zero to a compiled program you understand line by line.

Start with the toolchain and the language core: types, control flow, functions, and your first real classes. Every unit ends in code you compile and run yourself.

Prerequisite: None. A laptop and a terminal are enough.

Start course

You will be able to

Compile, link and debug a multi-file C++ project
Read and write modern C++ syntax with confidence
Use the standard library containers and algorithms
Reason about stack, heap and object lifetime

Lesson outline

Toolchain & first build

g++, CMake, compilation stages, reading compiler errors.

Project examples

PRJ-01

Sensor log parser

Read a robot telemetry CSV, compute min/max/mean per joint, print a formatted report.

std::vector<Sample> samples = load("joints.csv");
auto peak = *std::max_element(samples.begin(), samples.end(),
    [](auto& a, auto& b) { return a.torque < b.torque; });

PRJ-02

Joint limit checker

A small class that validates target angles against per-axis limits and reports violations.

class JointLimits {
public:
  bool allows(int axis, double deg) const;
};

PRJ-03

Terminal gripper sim

A loop-driven console program that opens/closes a simulated gripper and tracks payload state.

while (running) {
  auto cmd = readCommand();
  gripper.apply(cmd);
  render(gripper.state());
}
