A coroutine is a function that can suspend execution to be resumed later. Coroutines are stackless: they suspend execution by returning to the caller, and the data that is required to resume execution is stored separately from the stack. This allows for sequential code that executes asynchronously (e.g. to handle non-blocking I/O without explicit callbacks), and also supports algorithms on lazy-computed infinite sequences and other uses.| en.cppreference.com
When certain criteria are met, the creation of a class object from a source object of the same type (ignoring cv-qualification) can be omitted, even if the selected constructor and/or the destructor for the object have side effects. This elision of object creation is called copy elision .| en.cppreference.com
In this post, by Embedded I’m generally referring to deeply embedded/bare-metal systems as opposed to Linux-based embedded systems. Embedded systems and strings Historically, the need for and thus the use of strings in embedded systems was fairly limited. However, this has changed with the advent of cheaper, full graphic displays and the growth of the ‘Internet of Things’ (IoT). Many embedded systems sport full-colour graphics displays, supported by embedded-specific graphics libraries,...| Sticky Bits - Powered by Feabhas
