If you wish to use a for loop over a string this is possible in ruby. Create literals manipulate strings and use each char and each line.

Ruby strings use strings. Typically methods with names ending in modify their receiver while those without a return a new. Then you can use each on this array to iterate. Suppose we want to iterate over the characters or lines in a string.
