How to read and process one character at a time?

[Rainbowpride89]

I am writing a program that I need to be able to read and process one character at a time in C++. Do I use a string to do that? If so how would that go in synta form(an example). If you don't use strings then what do I use and how syntax(an example). Thanks

What do you mean, exactly, by "read and process one character at a time"?
Be specific about what you want to happen.

For an eample if I was to enter lklk or jgjgjg I need to be able to read and process each character to see if it is well-formed or not.

Repeating the same words in another sentence does not improve specificity. I can give you at least two completely different answers right now with the very general problem statement you have given me so far.

What exactly are you trying to do?
