Split a string into individual letters/characters?

[DeltaSmash]

I just started learning C++ a week or so ago and I kinda feel like making a little word mixer program. Basically the user enters a string (no numbers or punctuation for now) and I need to split up the string (anything from a simple sentence to an entire paragraph) into individual letters so that I can take those letters and do with then what I like.

Any help is appreciated.

A string is already "split up" in the sense that you can access individual characters using array syntax, e.g. mystring[0] for the first letter, mystring[4] for the fifth, and so on.

(Rocket, you can use brackets directly on a std::string; no need to convert it to a C string.)

Thanks guys. I was trying to figure out for a while how to make an unknown number of variables (because the user could enter one letter or a couple paragraphs) then the do..while loop hit me :)

do{
indChar=userText[userTextPos];
userTextPos++;
}while(userTextPos<userText.size());

Next level coding:

for(int userTextPos = 0; userTextPos < userText.size(); userTextPos++)
{
    indChar=userText[userTextPos];
}

Does the same thing. For situations like this where it's a simple loop, usually using a for block is the way to go :smile:

Yes I guess that does make it cleaner. Could even remove the curly braces and make it a one-liner.

Don't remove the curly braces, you'll spend more time adding/removing them then actually coding.

IMO that's a bit of an exaggeration, but I still agree. There are occasionally times where I absolutely know I won't need the curly brackets or that adding curly brackets will make it look messy, but for the most part I keep them in, looks cleaner.

Yeah, I was going to write that there's exceptions like guards at the start of a function to check if something isn't NULL and then immediately return, but I didn't really want to do the whole 'except if you absolutely know you won't', because from experience I've never known.
