2. Construit un bitset à l'aide des bits dans val. Si la N est la taille de la bitset et M est le nombre de bits mis en val, alors que min (N, M) bits seront inclus dans le bitset .

Original:

2. Constructs a bitset using the bits in val. If the N is the size of the bitset and M is the number of set bits in val, then only min(N, M) bits will be included in the bitset.

3. Construit un bitset utilisant les caractères de l'std::basic_string str. Un pos position optionnelle de départ et n longueur peut être fournie, ainsi que des caractères indiquant des valeurs de remplacement pour jeu (one) et unset (zero) bits .

Original:

3. Constructs a bitset using the characters in the std::basic_string str. An optional starting position pos and length n can be provided, as well as characters denoting alternate values for set (one) and unset (zero) bits.

La longueur effective de la chaîne d'initialisation est min (n, str.size() - pos) .

Original:

The effective length of the initializing string is min(n, str.size() - pos).

Si pos > str.size(), ce constructeur lève std::out_of_range. Si tous les caractères examinés dans str ne sont pas zero ou one, il jette std::invalid_argument .

Original:

If pos > str.size(), this constructor throws std::out_of_range. If any characters examined in str are not zero or one, it throws std::invalid_argument.
