This lesson

A recap and interview lens on Track summary—connecting earlier C++ lessons to systems and native-code expectations.

Interviewers expect RAII, rule of three/five, STL complexity, and when modern C++ beats C—not just syntax.

You will apply Track summary in contexts like: Game engines, trading systems, desktop apps, and performance-critical libraries.

Write C++ in main.cpp with int main(), click Run on server—the dev runner compiles with c++/g++ -std=c++17 -Wall and runs the binary; read template errors in stderr (LEARNING_RUNNER_ENABLED=true). Also read the interview prep blocks.

When earlier lessons and MCQs feel comfortable, or when you are interviewing for systems, embedded, or native roles.

You covered C++17 syntax, OOP, memory, STL, modern features, compilation, and interview context. Continue with small CMake projects locally and read A Tour of C++ or Effective Modern C++.

What you learned

  • Basics: variables, references, control flow, functions, namespaces
  • OOP: classes, inheritance, polymorphism, access, operators
  • Memory/STL: pointers, vectors, strings, maps, iterators
  • Modern: smart pointers, move, lambdas, templates, exceptions
  • Systems: headers, const/constexpr, algorithms, I/O, debugging

Next steps

  1. Build a CLI tool with CMake and multiple .cpp files
  2. Practice on exercism.org or Advent of Code in C++
  3. Compare patterns with C, Rust, and Java tracks

Self-check

  1. Name the smart pointer with exclusive ownership.
  2. What container replaces most raw dynamic arrays?

Tip: Your next milestone is a multi-file CMake project with tests—single-file playground skills transfer directly.

Interview prep

What to practice next?

Multi-file CMake projects with tests, STL-heavy exercises, and reading modern C++17 code with sanitizers enabled.
