Separate the string "Hello,How,Are,You,Today" by commas into an array so that each index of the array stores a different word. Display the words to the 'user', in the simplest manner possible, separated by a period. To simplify, you may display a trailing period.
Perl
Interpreter: Perl any 5.X
# in split, between the // goes a regex my @words = split(/,/, "Hello,How,Are,You,Today"); print join('.', @words); # does not include a trailing period
Alternate
my @words = split(/,/, "Hello,How,Are,You,Today"); print $_.'.' for (@words); # includes a trailing period
Or my personal favorite, the one liner
print join('.', split(/,/, "Hello,How,Are,You,Today"));
Ruby
string = "Hello,How,Are,You,Today".split(',') string.each do |w| print "#{w}." end
