Code Snippets

The code snippets are organized according to chapter and section.

Each code snippet in intended to be a complete standalone C++ project that compiles and runs on a PC. The code snippets correspond to individual code samples in the book but extend these in rudimentary ways to include a main subroutine and usually some sensible short messages to the output console.

Consider, for instance, the code snippet chapter03_11-001_array.cpp.

// A login key stored in an std::array.
constexpr std::array<std::uint8_t, 3U> login_key
{
  {
    UINT8_C(0x01),
    UINT8_C(0x02),
    UINT8_C(0x03)
  }
};

int main()
{
  std::cout.unsetf(std::ios::dec);
  std::cout.setf(std::ios::hex);
  std::cout.setf(std::ios::showbase);

  std::cout << "login_key is ";
  std::copy(login_key.cbegin(), login_key.cend(), std::ostream_iterator<unsigned int>(std::cout, ","));
  std::cout << std::endl;
}

This code snippet portrays simple use of std::array. An array named login_key is created and initialized with the data bytes 1,2,3. The bytes are printed to the output console.

The expected message text is

login_key is 0x1,0x2,0x3,
