Hi all,

I met a problem when I tried to write some Ruby code to learn Ruby. The
following code just can't work as expected,

"Hello".each_byte { |c|
    if c == "o"
        print "oh, i got an o!", "\n"
    end
}

Seems in Ruby, in the comparsion c and "o" is always false. How can I make
the above code right? Thanks a lot.
