cin, strings, and streamstrings??

Im confused =.=

I'd be happy to help you if you give us more information on what you're confused about.

cin is an object of a class, istream. I'm pretty sure I saw you use it in your calculator, I'm not sure.

[php]
string SomeString;

int main()
{
cin >> someString;
cout >> someString;
}
[/php]

cin asks for the users input ( hence the name, console input ), cout outputs it.

String is similar to a character array:
[php]
char array[];
[/php]

But I guess you haven't gotten that far yet. It's not exactly the same because a string ends with a null terminated character. "\0". You will never see this character, no matter how hard you try, but I assure you, it's there.

All of that came off the top of my head, I'm tired right now.
