A couple questions

[eli m]

1. First off, how do i make a while loop in c++?
2. Second, what is the most basic way to get input and then assign it to a variable?
3. How do i know what type of declaration (or whatever its called) to a variable? For example: int, long, float, char, double

What book on C++ are you reading that doesn't explain that?

2. Second, what is the most basic way to get input and then assign it to a variable?

cin >> variable

3. How do i know what type of declaration (or whatever its called) to a variable? For example: int, long, float, char, double

You know when you decide what it's used for. Usually *you* pick the
type, and not vice versa.

Sorry, for the last one i meant when do i assign a certain decleration to a variable. Likewhen do i use double etc.
