Choice B is correct: 10 rows of 13 stars.
Think of the inner loop as a module that "does something." The details of how it does it can be ignored if the description of what it does is accurate. Here is the program with part of the inner loop replaced by a box that represents a module:
' Do the loop body ten times FOR LINE = 1 TO 10 LET NUM = 13 +---------------------------------+ | | | Print NUM stars in a new row | | | +---------------------------------+ NEXT LINE ' END
Say that the 13 in the above program were changed to 9. What would the program print out?
