Having an int object, let's say the value is 2, I'd like to print
it out as "0002". I miss C's format strings. Any hints ? Thanks in
advance.

If it's there, and you can see it, it's real.
If it's not there, and you can see it, it's virtual.
If it's there, and you can't see it, it's transparent.
If it's not there, and you can't see it, you erased it.
def format3(int)
fmtStr = sprintf("%04d", int)
print "#{fmtStr}\n"
end
format3(2)

Miss them no longer:
>> value = 2
=> 2
>> sprintf "%04d", value
=> "0002"
>> "%04d" % value
=> "0002"

printf "%04d", 2
Ruby has format strings!

Another option:
irb(main):001:0> '%04d' % 2
=> "0002"
