Outdated behaviors die tough, so this rule is hard to apply continuously, Primarily as there are lots of instances wherever = is innocent.

Even so, not all kinds Use a default value and for a few sorts developing the default benefit might be expensive.

Men and women dealing with code for which that difference matters are rather capable of selecting in between array and vector.

// low cost: 1 increment handles this complete function and all the call trees down below us auto pin = g_p; // GOOD: passing pointer or reference attained from a neighborhood unaliased wise pointer file(*pin); // Very good: identical cause pin->func();

Typically you'll want to include and remove elements with the container, so use vector by default; when you don’t require to change the container’s measurement, use array.

Shared_ptr // A kind that matches Pointer, has copy, and matches the Life time profile conditions to get a shared proprietor variety; see wise pointers
