pointers to the data. Unfortunately, it’s more difficult to manage the lifetime of shared variables (for this reason, garbage collectors have become popular). Luckily, C++ 11 provides an elegant solution for working with shared variables through the std::shared_ptr template class, as shown in...
Helper template functions used to convert unary and binary function pointers, respectively, into unary and binary adaptable functions. Deprecated in C++11, removed in C++17.C++ Copy template <class Arg, class Result> pointer_to_unary_function<Arg, Result, Result (*)(Arg)> ptr_fun(Result (...

This is very different from doing it in a procedural style using iterators where you often end up with one off errors, null pointers and a host of other problems. By eliminating the possibility of making them we can write code quicker and be more productive. Java 8 Streams and supplied ...
Since persistent data structures use sharing in their implementation, the simplest thing to do is to replace naked pointers with shared pointers. Let’s start with the pointer to the head of the list: std::shared_ptr<const Item> _head; We no longer need to initialize _head to nullptr ...
Pointers are one of the key features in C and are hard to avoid entirely in any real-life application. In the context of C, ISO 26262 casts constraints for enforcing strong typing and also stipulates that pointer to integer conversions (and the other way around) are forbidden. Further, addi...
One way to create a linked list in C is to use pointers and dynamic memory allocation, as seen in this simple example: struct node { void *data; node next;};void add_data(node *n, void *val); In the preceding example, we store data in the linked list using void *. An example ...
Every story has to start somewhere. This one is a tour through a simplistic Scheme interpreter written in C, and every C program begins with themain()function. voidsetup_runtime(void);voiddo_useful_stuff(intargc,constchar**argv);voidteardown_runtime(void);intmain(intargc,constchar**argv)...
FluenC is a C-inspired, functional-first language, with a focus on simplicity. It's hard to know where to start explaining what FluenC is, and how it works, since the language uses many unique features that works in symbiosis to produce the end result: A language as easy as JavaScript...
