# compiler flags:
# -ansi: Use ANSI C
# -pedantic: Issue all warnings according to strict ANSI standard C
# -Wall: Turn on all Warnings. ALWAYS use this. You will benefit from it.
# -O2: Optimization Level 2, nearly all supported optimizations that do not involve a space-speed tradeoff are performed. Increases compilation time, but produces performance-enhanced code.
# -o: Specify output file to be created
