Conventions used

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

CodeInText: Indicates code words in the text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Mount the downloaded WebStorm-10*.dmg disk image file as another disk in your system."

A block of code is set as follows:

int main()
{
   std::cout << "Hello, World!\n";
}

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

template<typename C, typename... Args>
void push_back(C& c, Args&&... args)
{
   (c.push_back(args), ...);
}

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

$ mkdir build
$ cd build

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Select System info from the Administration panel."

Warnings or important notes appear like this.

Tips and tricks appear like this.
