decimals

i am fairly new to c++, i need to know how to make it so you can input
decimals into a file using the cin >> a command instead of just being
able to input whole numbers and also how to make it so that it outputs
decimals and not just rounded off whole numbers

What have you tried? (Show us some brief *real* code.)

Have you looked at a book? (See http://www.accu.org for suggestions.)

This ain't rocket surgery...

You need to decalre you variables as float or double.

double x;
cin >> x;
cout << x;

BTW they are called floating point numbers, not decimals.
