passing pointers to functions

The three ways to define a pointer are: 1 int * p;  2. int* p; 3. int *p; The habit is different.The three ways to define a function pointer are: 1. int *p (); 2. int * p (); 3. int* p (); 1. Pointer passing and reference passing In C, if you want

The following is an overview of what you can say in plain words: Pointers-For a type t,t* is a pointer to T type, that is, a variable of type t* can hold the address of a T object, and type T can add some qualifiers, such as const, volatile

To understand the difference between value passing, pointer passing, and reference passing, the main purpose is to understand the arguments and parameters of the function, the scope of the function (automatic variables, stacks), the layout of the

Standard C ++ does not have real Object-Oriented function pointers. This is a pity, because Object-Oriented function pointers (sometimes called delegates) have proved their value in other languages. In Delphi (Object-Oriented PASCAL Language),

An important feature in C + + is pointers, which not only have the ability to obtain addresses, but also have the ability to manipulate addresses. Pointers can be used in arrays, or as parameters for functions, to access memory and operations on
