Advanced C++ Programming Cookbook

Conventions used

There are a number of text conventions used throughout this book.

constexpr: Indicates code words in text, numbers, folder names, filenames, file extensions, pathnames, dummy URLs, and user input. Here is an example: "The noexcept specifier is used to tell the compiler whether a function may or may not throw a C++ exception."

A block of code is set as follows:

int main(void){    the_answer is;    return 0;}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

int main(void){    auto execute_on_exit = finally{[]{        std::cout << "The answer is: 42\n";    }};}

Any command-line input or output is written as follows:

> mkdir build && cd build> cmake ..> make recipe04_examples ...
