Atunci  de ce editorul Microsoft Visual Studio nu se plange daca scriu myvector.capacity ? din moment ce capacity nu ar exista ci ar exista doar  functia capacity() ?
De ce nu-mi semnalizeaza cu rosu linia myvector.capacity  ? Daca variabila capacity nu exista ?

Ia uite pana si Visual Studio va contrazice: Intelisensului imi spune ca dpdv al OOP exista doar campul public capacity.
