Assignment 3: ASCII Art (Due: Th, April 24)

Provide the missing definitions for the declared procedures of the given program. The program should produce a picture similar to the displayed figure.

Notes.

• Submit your source file ‘turtle.cpp’ with the ‘submit c230aa lab3 turtle.cpp’ command.

Suggestions. Build your program incrementally. For instance, as described below.

• Comment out the calls to ‘drawHouse’ and ‘drawPerson’ in ‘main’, and provide empty-body definitions to the procedure declarations that are provided without definitions.
• Uncomment the call to ‘drawHouse’ in ‘main’, and comment out the call to ‘drawRoof’ in ‘drawHouse’
• Uncomment the call to ‘drawRoof’ in ‘drawHouse’.

  Note. The drawing of a line of length $d$ at direction $\alpha$ can be digitized to a painting of the coordinates

  (i * dx, i * dy)

  for $i=0,1,\dots ,n$ where

  $$\begin{array}{ccc}\hfill n& \hfill =\hfill & \left|d\right|\hfill \\ \hfill dx& \hfill =\hfill & \frac{d}{n}cos\left(\alpha \right)\hfill \\ \hfill dy& \hfill =\hfill & \frac{d}{n}sin\left(\alpha \right)\hfill \\ \hfill \end{array}$$

• Uncomment the call to ‘drawPerson’ in ‘main’.
