1)

Copia-costruisce il c sottostante contenitore con il contenuto di cont. Questo è anche il (C fino + 11) costruttore predefinito

Original:

Copy-constructs the underlying container c with the contents of cont. This is also the default constructor (C fino + 11)

2)

Spostare-costruisce il contenitore sottostante c con std::move(cont). Questo è anche il (dal C++11) costruttore predefinito

Original:

Move-constructs the underlying container c with std::move(cont). This is also the default constructor (dal C++11)

5-9)

I seguenti costruttori sono definite solo se std::uses_allocator<container_type, Alloc>::value == true, cioè, se il contenitore sottostante è un allocatore-consapevole contenitore (vale per tutti i contenitori della libreria standard).

Original:

The following constructors are only defined if std::uses_allocator<container_type, Alloc>::value == true, that is, if the underlying container is an allocator-aware container (true for all standard library containers).

Costruisce il contenitore sottostante utilizzando alloc come allocatore. Chiama efficacemente c(alloc).

Original:

Constructs the underlying container using alloc as allocator. Effectively calls c(alloc).

6)

Costruisce il sottostante contenitore con il contenuto della cont e utilizzando alloc come allocatore. Chiama efficacemente c(cont, alloc).

Original:

7)

Costruisce il contenitore sottostante con i contenuti della cont con semantica di spostamento, mentre utilizzando alloc come allocatore. Chiama efficacemente c(std::move(cont), alloc).

Original:

Constructs the underlying container with the contents of cont using move semantics while utilising alloc as allocator. Effectively calls c(std::move(cont), alloc).
