Variable storage

[closed account 3R5fjE8b]

Is there any right way to store a collection of variables inside a class?
The second is a little more complicated, but easily accessed in for loops.

private:
   int var1, var2, var3, var4, var5, var6;

or

private:
   enum variables { var1, var2, var3, var4, var5, var6 };
   int variable_storage[var6+1];

Use a std::vector in general:

Use a std::array or std::tuple when you know the size at compile time:
