use of substr find and []

rohanshah1 (32)
ok guys this is my code here well my problem is the code wont show up the way its supposed this is what it should do:
//Read a line of 5 words separated by colons and no spaces.
//Extract the 5 words
//Print the 5 words in reverse order, one word per line.
i think my code is alright but when it tried to put them in reverse order it doesn't seem to do it right.

ok i typed in
:hi:hello:kemcho:bonjour:kaiseho

i should have got:
kaiseho bonjour kemcho hello hi

You look for the position of the first delimiter before removing the colon from the beginning of the string, so your first word is always the empty string. Thus, when you get to the end you have two words remaining as your fifth word.
