The Standard C++ syntax ... size_t size, const char * file, int line); void operator delete ... the placement delete function that is called will be operator delete ...
The C++ standard library instead provides a dynamic array (collection) that can be extended or reduced in its std::vector template class. The C++ standard does not specify any relation between new / delete and the C memory allocation routines, but new and delete are typically implemented as wrappers around malloc and free. [6]
All the operators (except typeof) listed exist in C++; the column "Included in C", states whether an operator is also present in C. Note that C does not support operator overloading. When not overloaded, for the operators && , || , and , (the comma operator ), there is a sequence point after the evaluation of the first operand.
In C++03 before the introduction of move semantics (in C++11) the special member functions [5] were: Default constructor (if no other constructor is explicitly declared) Copy constructor
Should C++'s placement new and placement delete operators also go in the table? void * operator new (size_t, void *) throw(); void operator delete (void *, void *) throw(); Darthmarth37 04:58, 1 November 2009 (UTC) A link in the table would be enough (or a * link to below the table), but I doubt it's appropriate to emphasize it too much.
The C++ Standard Library provides several generic containers, functions to use and manipulate these containers, function objects, generic strings and streams (including interactive and file I/O), support for some language features, and functions for common tasks such as finding the square root of a number.

It is, however, preferable to use an algorithm from the C++ Standard Library for such tasks. [1] [2] [3] The member function erase can be used to delete an element from a collection, but for containers which are based on an array, such as vector, all elements after the deleted element have to be moved forward to avoid "gaps" in the collection ...
