# 0) Count the number of semi-colons

# 2) Count the number of total non-space chars in all of the source code lines
# 3) Count the number of total non-space chars in all of the documentation lines
# 4) Separate out the copyright header comment lines from the other comment
# lines and print the line counts for these separately
