Is there a way to statically-initialize a dynamically-allocated array in C++?

Question

In C++, I can statically initialize an array, e.g.:

int a[] = { 1, 2, 3 };

Is there an easy way to initialize a dynamically-allocated array

Answer 1

Never heard of such thing possible, that would be nice to have.

Keep in mind that by initializing the array in the code that way

int a[] = { 1, 2, 3 };

..... only gains you easier code writing and NOT performance. After all, the CPU will do the work of assigning values to the array, either way you do it.
