That is the way String indexing works in Ruby=2C if you only pass one param=
eter you'll get the ASCII value of the character. If you would like to get =
"h" you must do  a[0=2C1] where the first parameter tells the parser to get=
 the first character of the String and the second parameter tells the numbe=
r of characters you want to get from that position.
Hope this helps
