The second in C++ only. So please all, explain what programming language =
you
are referring to, so as to avoid confusions.

The *initial* size of built in arrays...

For built in arrays, no (except of int vetc[10]; of course).

Use the second. The first is used in C because the second is not =
availlable.
Also keep in mind that C and C++ are very different languages now.

The second. But standard library containers should be preferred more.
