Converts the quantity of each festive gift to binary using a function.

The colour version will work on a Raspberry Pi, but not MinGW C++ under Windows. Colour version also uses the sleep() function to slow the program down rather than displaying the whole lot almost instantaneously.

For best results on a classroom projector, change the size of your font in the Terminal window (looks nice). On a Pi using LXTerminal, go to the Edit menu, choose Preferences and change font size to 22 (ish).

Standard C++ program that will compile and run on a Raspberry Pi. You can also compile it in Windows if you have MinGW or some other version of C++.

Raspberry Pi has the GNU Compiler Collection installed as part of the Debian or Raspbian operating system installations.

This C++ code can be compiled using the g++ compiler.

It is written using the C++ 98 standard so will compile on most Bronze Age settlements. Alternatively, you should be able to paste the code into repl.it web-site and run it there.

Comments are included to show you what each part of the code does if you have never seen any C++ before.

It was knocked up quickly yesterday for a bit of fun, but I have used more modern C++ style rather than older C-style features e.g. use of “cout” to display things on the screen, “endl” rather than ‘\n’ new-line characters.

Compile from command line in Linux using…

g++ 12-days-of-christmas.cpp

…which will make an executable a.out file.

To run…

./a.out

Deluxe compilation option…

g++ -o song 12-days-of-christmas.cpp

…which will create an executable called song.

Not entirely pointless: functions, constants, arrays, iteration and output. Bonus.
