ostrstream(); (1) ostrstream(char* s, int n, std::ios_base::openmode mode = std::ios_base::out); (2) Constructs new output strstream and its underlying std::strstreambuf. 1) Default-constructs the underlying std::strstreambuf, which creates a dynamically growing buffer, and initializes the base class with the address of the strstreambuf member. 2) Initialized the base class with the address of the underlying std::strstreambuf member, which is initialized in one of the two possib

Discards any whitespace characters (as identified by calling isspace()) until the first non-whitespace character is found, then takes as many characters as possible to form a valid base-n (where n=base) integ

reverse_iterator rbegin(); const_reverse_iterator rbegin() const; const_reverse_iterator crbegin() const; (since C++11) Returns a reverse iterator to the first element of the reversed container. It corresponds to the last element of the non-reversed container. Parameters (none). Return value Reverse iterator to the first element. Exceptions (none) (until C++11) noexcept specification: noexcept (since C++11) Complexity Constant. See also rend crend r

size_type max_size() const; Returns the maximum number of elements the container is able to hold due to system or library implementation limitations, i.e. std::distance(begin(), end()) for the largest container. Parameters (none). Return value Maximum number of elements. Exceptions (none) (until C++11) noexcept specification: noexcept (since C++11) Complexity Constant. Notes This value is typically equal to std::numeric_limits<size_type>::max(), and reflects the

Declarations introduce (or re-introduce) names into the C++ program. Each kind of entity is declared differently. Definitions are declarations that are sufficient to use the entity identified by the name. A declaration is one of the following: Function declaration Template declaration Explicit template instantiation Explicit template specialization Namespace definition Linkage specification Attribute declaration (attr ;) (since C++11) Empty declaration (;) Block declaration (a
