3)

Создает строку с подстроки [pos, pos+count) из other. Если запрашиваемая подстрока продолжается после конца строки, или если count == npos, в результате подстрока [pos, size()). Если pos >= other.size(), std::out_of_range выбрасывается.

Original:

Constructs the string with a substring [pos, pos+count) of other. If the requested substring lasts past the end of the string, or if count == npos, the resulting substring is [pos, size()). If pos >= other.size(), std::out_of_range is thrown.

Создает строку с первыми символами count из символьной строки, на которую указывает s. s может содержать нулевые символы. s не должно быть NULL указателя.

Original:

Constructs the string with the first count characters of character string pointed to by s. s can contain null characters. s must not be a NULL pointer.

Конструкции строку с содержимым нулем строку символов, на которую указывает s. Длина строки определяется первым символом NULL. s не должно быть NULL указателя.

Original:

Constructs the string with the contents of null-terminated character string pointed to by s. The length of the string is determined by the first null character. s must not be a NULL pointer.
