Conventions used

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

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “This is where the genius of std::vector shines; over-allocating reduces the need for frequent and, potentially, computationally costly reallocations.”

A block of code is set as follows:

template <typename T,
          typename AllocatorPolicy = std::allocator<T>>
class CustomVector {
  // Implementation using AllocatorPolicy for memory
  // allocation
};

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

Time without reserve: 0.01195 seconds
Time with reserve:    0.003685 seconds
