graphics/image.h can be used to create, view, load and save images. Example:

graphics/image_event.h allows for interactive graphical programs with animation and mouse event handling.

Karel the Robot is a gentle introductory programming language created by Professor Richard Pattis in Karel the Robot: A Gentle Introduction to The Art of Programming and implemented in C++ here with his permission. The Karel language emphasizes logic while hiding tricky syntax, allowing anyone to begin making exciting graphical programs with very little background.

Karel lives in a two-dimensional grid and has a position and an orientation (north, east, south or west). Each cell of the grid may contain one or more beepers, or no beepers at all. Karel has a bag of beepers (which may be empty). Cells may be separated by walls.

Karel has four actions: they can move forward, turn left, put down a beeper or pick up a beeper. In addition, Karel is able to check state of the area around themselves. Karel cannot move through walls or off the edge of the world.

Karel programs may export the world to CSV after each action. This may be helpful to screen-reader users.

Karel programs may prompt before each robot action. This may be helpful for users who need to control the speed of execution.

To create Karel the Robot programs in C++, include karel/karel.h.
