P3: WAP to... REDONE

What I learnt:
  •  In plotting points for drawpoly or fillpoly, if you're using fractions instead of decimal points, it should be followed by a decimal point. eg: instead of 0.5, use (1.0/2.0)

  • Functions like fillpoly(), filleclipse() creates a border on its own. Hense, both setcolor() and setfillstyle() can be used to customize the fill_ functions.

  • Take Note of the flying bird, use of arcs. Easy to implement, but looks difficult.

  • Room for improvement?
    Draw a boat, some floating lotus leaves, or a floating house boat.
    Make Sun so large, it's masked slightly by both mountains.
