Intricate effects can be created by nesting
for loops inside other
for loops. What happens when you add more colors or numbers to the outer or inner loops? How many shapes are drawn when you change the repetitions? Can you change the arrangement of the shapes?
Loop variables stand for different values each time the loop is run.
c goes through different colors.
x go through different numbers. How would you use a loop variable to label each corner with a different number?
