# printf vs. echo
# printf comes from C/C++ and offers a way to print ordinary characters"

printf "hello printf\n"

# echo sends a newline at the end of it's output by default

echo "this was an echo"

# printf can take integer, double and floating number arguments
# make sure that your shell supports these features
# for example, bash supports format specifiers:

printf "%s\t%s\n" "1" "2 3" "4" "5"
