Lavavej, you want to make the most of this piece of feedback.
Here I want to flesh out one these pieces of advice that he gave.
However, if array is a vector, this won’t happen, because the memory will be deallocated as soon as array goes out of scope (regardless of whether the function exits early or not).
This makes std::vector much safer to use than doing your own memory allocation.
The – suboptimal – way to inserting several elements by using , just as if we were discovering each time that there was yet another element to append.
This potentially causes multiple reallocations of the vector.
This really ties in with a similar guideline we saw when searching into a container with the STL.
In the previous lesson, we introduced std::array, which provides the functionality of C ’s built-in fixed arrays in a safer and more usable form.
While such iterators are very handy, it is important to realize that in some cases you don’t want to use them.
And these cases come down to inserting several consecutive elements into an STL container.
