So far as we can easily convey to, these policies cause code that performs in addition or better than older, a lot more common tactics; they are supposed to follow the zero-overhead basic principle (“Everything you don’t use, you don’t pay for” or “any time you use an abstraction mechanism appropriately, you will get no less than nearly as good overall performance as should you experienced handcoded utilizing lessen-amount language constructs”).

// low cost: one increment handles this whole operate and all the call trees down below us auto pin = g_p; // Very good: passing pointer or reference acquired from an area unaliased good pointer file(*pin); // Excellent: very same reason pin->func();
