Re: [Dev-C++] encoding

Hi again!

I like answering your questions sometimes. It's good practice for the skills
I have managed to develop so far. I assume it's for a lesson or such?

If you are generating an output string then using a string to store it isn't
hard, all you need to do is append each letter as it is generated onto the
output string, when you output it all you do is just reinitialise it to an
empty string to start again. The C++ std::string would be best (use += to
append), but it could be done with a C null terminated string, with a little
more work, just keep track of the index (or pointer) into an array, move it
on as you add each letter, and null terminate it before displaying. Just
makesure that you don't overrun the arrays bounds.

If you are looking to use a container type then a queue would be suited,
push your letters into the queue and then, to display them, just pop them
off one at a time until the queue is empty.

As I like to I have made a small program that follows what you have said
(AFAICT), but I don't know all the rules so you can implement the rest
yourself.

Jason.
