# Display the lines.

# The print_lines function is a recursive function that

# accepts an integer argument, n. The function displays

# n lines of asterisks on the screen, with the first

# line showing 1 asterisk, the second line showing 2

# asterisks, up to the nth line which shows n asterisks.
