# Week One Exercise 2
# Read the sprintf documentation and the % documentation in the 
# String class and figure out the output being printed by of this Ruby code.

puts "%05d" % 123

# The output is 00123

# Similar to Python, % can be used as a formatter.
# I looked up the usage of 'd' as an argument formatter in the
# ruby docs, 'd' converts the argument as a decimal number.

# There was no decimal point in our code, so Ruby "tacks on" two zeros
# proceeding 123 (I think)
