modern-cpp-challenge

Code implementations for various C++ challenges as found in the book The Modern C++ Challenge. The code is organized into folders that follow the various sections of the books. Each solutions will include a readme or a full write up on my blog.

Building the Code

The code in this repository requires:

• C++17 compliant compiler
• CMake

Optionally, you can also build unit tests for most of the code. If you turn this option on, you will also need:

• GTest

Simply configure and build with CMake. No other external dependencies are needed.

Challenges

Language Features

IPv4

This challenge involved modeling an IPv4 address in C++. The specific requirements were:

• Be able to read an address from a string like:

ip::address addr = ip::from_string("127.0.0.1");

• Be able to write an address to a string.
• Be able to enumerate a range of addresses; for example:

ip::address start = {0,0,0,0};
ip::address end = {255, 255, 255, 255};

while(start < end)
{
  start++;
  std::cout << start << std::endl;
}

Full write up is availble on my blog.

2D Array with Basic Operators

This challenge involved modeling a 2D array in C++ with support for:

• Element access (at() and data())
• Capacity querying
• Iterators
• Filling
• Swapping
• Movable

mcc::matrix<double, 3, 3> data;
std::iota(data.begin(), data.end(), 1.0);
/*
  data now looks like
  1.0, 2.0, 3.0,
  4.0, 5.0, 6.0,
  7.0, 8.0, 9.0
*/
