Newgrammer Development Tools

A repository of simple demo applications that show new programmers how to write code in C++.

The various concepts exhibited include data structures, algorithms, threading, memory management, graphics, event handling, and the like.

This code only runs on the Windows platform, but all the platform specific parts of creating a window, handling mouse, keyboard, joystick and the like are conveniently wrapped up in one place, and the programmer doesn't really deal with it.

Compiling

The projects directory contains a Visual Studio solutions file which gives you ready access to all the coded up examples.

Install a relatively recent version of the Visual Studio environment, to get a Visual C++ compiler installed. Currently using Visual Studio 2019

Open up the projects.sln file in the \projects\projects.sln Make sure you're in Release mode Build the entire solution, play with examples

Some Details

Graphics are supported by the blend2d library. Other than that, there are no other external dependencies.

In the directory structure, the '\primary' directory contains a bunch of very useful stuff that makes the programming super easy to play with. The most direct and easy way to get started is to use the p5 combination of files. These files give you a programming environment which is very familiar to what you would have in p5.js, but using C++ instead of javascript.

* apphost.h
* appmain.cpp

* p5.hpp
* p5.cpp

With these files included in your project, you have an environment where you only need to implement a couple of functions to put something on the screen.

void setup()
{
    createCanvas(640,480);
}


void draw()
{
    // draw a rectangle
    rect(10,10,100,100);
}

Creating a new project

Add libraries: blend2d.lib, ws2_32.lib
Set Additional Lib Directories to ....\lib\Release
Set C/C++ Additional Include Directories - ....\primary
Set C++ runtime to /Mt

Bits And Bobs

Most functions in ndt are in classes that are in header files. That means ndt does not have a 'library' that programs link against. Each program is individual, and compiles down to a fairly small size.

Things to try

Processing and P5 worlds are full of great things to play with.
