Homework 2 (ASCII Art / Space Needle) FAQ

Q: How do I figure out what my loop should go up to? I don't understand nested loops!
A: The outer loop is the "vertical" loop and is fairly simple; it generally counts the lines from 1 to however many lines there are in that section of the figure. The inner loop is the "horizontal" one and requires more skill to get right. Use an inner loop for every portion of the line that is repeated, and use the slope-intercept formula and loop tables (as shown in class) to figure out how many repetitions to use.
Q: How do I add in the scale variable?
A: Try making a loop table at two different figure sizes and compare expressions from size 10 to size 16 (for example), to help factor out the scale variable.
Q: What resources can I use to help me get started?
A: Chapter 2's case study goes through the process of solving a very similar problem.
Q: Why are there blank lines at random places in my output?
A: This is the result of a known jGRASP bug. Your code is most likely fine if the output works for another scale value.
