21st century c c tips from the new school

You're looking for some modern C++ tips from the "new school"! Here are some best practices and techniques that are commonly used in the 21st century:

  1. Use modern C++ features: Take advantage of C++11, C++14, and C++17 features, such as auto, constexpr, move semantics, and range-based for loops.
  2. Avoid raw pointers: Prefer smart pointers (unique_ptr, shared_ptr) and containers (vector, list) over raw pointers and manual memory management.
  3. Use const correctness: Use const whenever possible to ensure that objects are not modified unintentionally.
  4. Use RAII (Resource Acquisition Is Initialization): Use smart pointers and containers to manage resources, such as memory and file handles, to ensure they are properly cleaned up.
  5. Use move semantics: Use move semantics to transfer ownership of objects efficiently, reducing the need for unnecessary copies.
  6. Use perfect forwarding: Use perfect forwarding to forward arguments to functions without losing information about their types.
  7. Use constexpr: Use constexpr to evaluate expressions at compile-time, reducing the need for runtime computations.
  8. Use lambdas: Use lambdas to create small, one-off functions that can be used as closures or as arguments to higher-order functions.
  9. Use std::optional: Use std::optional to represent optional values, reducing the need for null pointers and improving code readability.
  10. Use std::variant: Use std::variant to represent a value that can be one of several types, improving code flexibility and readability.
  11. Use std::variant::visit: Use std::variant::visit to perform operations on values of different types, reducing the need for explicit type checks.
  12. Use coroutines: Use coroutines to write asynchronous code that is easier to read and maintain than traditional callback-based code.
  13. Use parallelism: Use parallelism to take advantage of multi-core processors and improve performance in computationally intensive tasks.
  14. Use profiling tools: Use profiling tools, such as gprof or Intel VTune Amplifier, to identify performance bottlenecks and optimize code accordingly.
  15. Use code analysis tools: Use code analysis tools, such as clang-tidy or cppcheck, to identify coding errors and improve code quality.
  16. Use version control: Use version control systems, such as Git, to manage code changes and collaborate with others.
  17. Use continuous integration: Use continuous integration tools, such as Jenkins or Travis CI, to automate testing and build processes.
  18. Use code review: Use code review to ensure that code is reviewed and tested before it is merged into the main codebase.
  19. Use testing frameworks: Use testing frameworks, such as Google Test or Catch2, to write unit tests and integration tests for your code.
  20. Use documentation tools: Use documentation tools, such as Doxygen or Javadoc, to generate documentation for your code and make it easier to understand.

These are just a few of the many modern C++ best practices and techniques that are commonly used in the 21st century. By following these guidelines, you can write more efficient, readable, and maintainable code.
