You should learn C++ and common techniques before to comment what
experienced developers do or say. For example, std::vector,std::string,
reserve double space each time they exceed in capacity. That's a common
optimisation in “contiguous” containers like std::string and std::vector
(the goal is to lower the number of allocation then copy of handled
objects).
That's explained in Effective C++ from Meyers (Addison Wesley editions).
