Increment number of variables?

Is it possible to make an increasing set of variables?

I.E.
Input: Amount of variables you want
Output: said amount of variables (similar names, i.e. C1, C2, C3...)

or

Input: Nothing
Output: Incrementing amount of variables with similar names (like a type of infinite loop)

Well, put the values in a std::vector and run it through a for_each; giving an 'increment' function as an argument.
