InC programming language, we can have a concept of Pointer to a function known asfunction pointer in C. In this tutorial, we will learn how to declare a function pointer and how to call a function using this pointer. To understand this concept, you should have the basic knowledge ofFunctio...

Read:Pointer Rules in C programming language. Declaration of a pointer to pointer (double pointer) in C When we declare a pointer variable we need to usedereferencing operator(asterisk character), similarly, to declare pointer to pointer, we need to use two asterisk characters before the identifi...
In C++, a generic pointer is a pointer of type void*, which can point to any data type. In this tutorial, you will learn how to use generic pointers with examples.
If you really want to use function pointers in C++, you can still use the same C-style syntax shown above or the type aliases below. As a function pointer type alias: using typeName = returnType (*)(parameterTypes); (example code) As a function type alias: using typeName = returnType...
C++ Pointer to Pointer - Learn about pointers to pointers in C++ with examples and detailed explanations to enhance your programming skills.
In principle, pointers are meant to point to valid addresses, such as the address of a variable or the address of an element in an array. But pointers can actually point to any address, including addresses that do not refer to any valid element. Typical examples of this are uninitialized ...
We consider a few examples: C[edit] In C, a pointer is a first class object. A pointer may be used in any place where it is appropriate. Pointers may be assigned to each passed to functions, and returned from functions. They may be converted to other values, they may be printed ...
