The Standard C++ syntax for a non-placement new expression is [2]. new new-type-id ( optional-initializer-expression-list). The placement syntax adds an expression list immediately after the new keyword.
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.
C++ provides more than 35 operators, covering basic arithmetic, bit manipulation, indirection, comparisons, logical operations and others. Almost all operators can be overloaded for user-defined types, with a few notable exceptions such as member access (. and .*) and the conditional operator. The rich set of overloadable operators is central ...
void write (table & t); //write the table structure into a file void read (table & t); //read the table structure from a file friend void del (table & t); //delete the table files, header and data files void print (table & t); //print the table on the screen friend std:: ostream & operator << (std:: ostream & o, table & t); //print the table ...
The modulo operator provides an example of a C program translating incorrectly under a C++ environment. Plebbeh 00:00, 26 August 2011 (UTC) Something needs to be done about the new and delete operators. First, new/delete definitely aren't in C. — Mobius 02:40, 30 August 2006 (UTC) Right, that's why it says "no" under "in C?"

The void pointer, or void*, is supported in ANSI C and C++ as a generic pointer type. A pointer to void can store the address of any object (not function), [ a ] and, in C, is implicitly converted to any other object pointer type on assignment, but it must be explicitly cast if dereferenced.
