Outputting a string backwards?
March 13, 2002 06:29 PM
Simple newbie question:
How do I get a string in a char array and then output it backwards? I tried a few things, but I can''t seem to get it to work right without outputting the extra parts of the array that gives me a result like
#*$#^@#$#$@esseJ
(with the name inputted as Jesse)
Anyone care to help a noob?

Thanks for the help, I got it! 
My code was almost exactly like Will''s except I was using strlen incorrectly. Oluseyi those are some nifty functions that I haven''t learned yet. Argh, they make you do everything the hard way don''t they...

Yeah, you feel pretty wasted when you find a function that does what you need - and is probably written in assembly so it''s faster than your version. Don''t worry, you''ll figure ''em out.
One thing you might want to do is look through header files and see what functions are in there. Also spend some time reading documentation and not programming.
