And their main takeaways

Daily bit(e) of C++ | Standard layout types

19 implied HN points • 26 Jan 24
🕹 Technology Programming
  1. offsetof only works for standard layout types
  2. pointer to a standard layout type and its first member are pointer-interconvertible
  3. standard layout union with standard layout structs allows access to common initial sequence through non-active members

Daily bit(e) of C++ | std::find_first_of

19 implied HN points • 25 Jan 24
🕹 Technology Programming
  1. The std::find_first_of algorithm in C++ finds the left-most matching element in a range.
  2. Both ranges in std::find_first_of are not ordered, resulting in quadratic complexity.

Daily bit(e) of C++ | Unscoped Enum

19 implied HN points • 21 Jan 24
🕹 Technology Programming
  1. Unscoped enumerations introduce named constants into a scope.
  2. The compiler automatically selects the backing type, unless explicitly specified.
  3. C++11 Scoped Enumerations are generally preferred over unscoped ones.

Daily bit(e) of C++ | std::stack

19 implied HN points • 19 Jan 24
🕹 Technology Programming
  1. std::stack is a container adapter for stack/LIFO functionality in C++.
  2. It helps in avoiding recursion and can be used for implementing undo functionality.

Daily bit(e) of C++ | std::osyncstream

19 implied HN points • 18 Jan 24
🕹 Technology Programming
  1. C++20 introduced synchronized streams.
  2. Multiple synchronized streams can be used to write to a single destination stream without introducing data races.
  3. All accesses to a stream should be through a synchronized stream to avoid interleaving.

Daily bit(e) of C++ | Rule of zero

19 implied HN points • 17 Jan 24
🕹 Technology Programming
  1. The 'Rule of zero' is based on the single responsibility principle.
  2. A class should not have special member functions unless it's managing ownership.
  3. Following the 'Rule of zero' can help in avoiding complexity in class design.

Daily bit(e) of C++ | std::print, std::println

19 implied HN points • 11 Jan 24
🕹 Technology Programming
  1. C++23 introduces std::print and std::println as alternatives to std::format for outputting to stdio FILE descriptors.
  2. Both std::print and std::println default to outputting to standard output (stdout).
