a virtual function (or method), most compilers add a hidden member variable to the class that points to an array of pointers to (virtual) functions called...

A function pointer, also called a subroutine pointer or procedure pointer, is a pointer referencing executable code, rather than data. Dereferencing the...

Pascal, a virtual function or virtual method is an inheritable and overridable function or method that is dispatched dynamically. Virtual functions are an...

object-oriented programming, pointers to functions are used for binding methods, often using virtual method tables. A pointer is a simple, more concrete...

bugs, dangling/wild pointer bugs frequently become security holes. For example, if the pointer is used to make a virtual function call, a different address...

In computer science, a tagged pointer is a pointer (concretely a memory address) with additional data associated with it, such as an indirection bit or...

"\n"; orig_VirtualFn1(thisptr); //Call the original function. } int main() { VirtualClass* myClass = new VirtualClass(); //Create a pointer to a dynamically...

override the virtual inner classes it inherited from the base class. An object of the child class may be referred to by a reference or pointer of the parent...

name-to-implementation mapping for a given class as a set of member function pointers. This is purely an implementation detail, as the C++ specification...

For example, the virtual machine might only allow the code access to a certain set of functions or data. The same controls over pointers which make automatic...

to function, function-to-pointer conversion does not take place (see f_func above), but it does take place when initializing a reference to function pointer:...

because virtual function calls are not bound until the time of invocation; single dispatch (i.e., single-argument polymorphism), because virtual function calls...

of a function object is in writing callback functions. A callback in procedural languages, such as C, may be performed by using function pointers. However...

any expression resulting in a null pointer. #include <iostream> #include <typeinfo> class Person { public: virtual ~Person() = default; }; class Employee...

the library function malloc is used to allocate a block of memory on the heap. The program accesses this block of memory via a pointer that malloc returns...

In computer science, a dispatch table is a table of pointers or memory addresses to functions or methods. Use of such a table is a common technique when...

spots can be considered of virtual infinite size, so the hot corners and edges can be reached quickly by throwing the pointer toward the edges. While a...
