cin means c input , you need a variable to take the input. Here is an example

</div><table border='0' align='center' width='95%' cellpadding='3' cellspacing='1'><tr><td><b>CODE</b> </td></tr><tr><td id='CODE'>
int homerx;
cin >> homerx;
</td></tr></table><div class='postcolor'>
The variable stores the input for later use. And in the console window there will be those blinky lines waiting for user input.

cout mean c out, this basically puts text on the console. Example:

</div><table border='0' align='center' width='95%' cellpadding='3' cellspacing='1'><tr><td><b>CODE</b> </td></tr><tr><td id='CODE'>
cout << "Homerx" << endl;
</td></tr></table><div class='postcolor'>

This puts homerx on the console window. or you can do it with a variable.

</div><table border='0' align='center' width='95%' cellpadding='3' cellspacing='1'><tr><td><b>CODE</b> </td></tr><tr><td id='CODE'>
char homerx = "S";
cout << homerx << endl;
</td></tr></table><div class='postcolor'>

Hope this helps, here are some great links for tutorials

actually cin and cout input and output to the default input/output devices
(usually the console) but they can be set to in/out to/from other places

This makes more sense when you get into classes (make your own string class, or something similar) and you start overloading the insertion and extraction operators.

Wow. This actually helped me in my incredibly slow learning of C++. Thank you first poster guy, and those afterward!

Java is much less arcane when it comes to input/output stuff, but then again, it's Java, so you can't actually use it for much of anything. <img src='http://www.unknownworlds.com/forums/html//emoticons/biggrin.gif' border='0' style='vertical-align:middle' alt='biggrin.gif' />

java is annoying

I once knew C++ and Java in and out. Now I only know C now, and I'm trying to remember how classes work. *scratches head and clicks on tutorial links*

Doesn't the c stand for condition or something?

<-- knows that they do, but doesn't have a compiler, or taken a class in 3 years.

The c stands for command or console, depending on your OS (win or *nix respectivily) iirc

Bah! Those are shift operators! std::string just uses them for stream I/O.
