Output:-

*The car moves in the output.

The abbreviations and the definitions of the list of graphic functions used are:

1. Initgraph:- It initializes the graphics system by loading the passed graphics driver then changing the system into graphics mode.

2. Getmaxx:- It returns the maximum X coordinate in current graphics mode and driver.

3. Setcolor:- It changes the current drawing colour. Default colour is white. Each color is assigned a number, like BLACK is 0 and RED is 4. Here we are using colour constants defined inside graphics.h header file.

4. Setfillstyle:- It sets the current fill pattern and fill color.

5. Circle:- It draws a circle with radius r and centre at (x, y).

6. Floodfill:- It is used to fill a closed area with current fill pattern and fill color. It takes any point inside closed area and color of the boundary as input.

7. Cleardevice:- It clears the screen, and sets current position to (0, 0).

8. Kbhit:- It is used to determine whether a key is pressed or not. It returns a non-zero value if a key is pressed otherwise zero.

9. Delay:- It is used to suspend execution of a program for a M milliseconds.

10. Closegraph:- It unloads the graphics drivers and sets the screen back to text mode.
