The return value of a function pointer is an array of pointers, where the return value of an int function pointer is an array of pointers, and an int pointer is placed in the array.#include #include voidFunintA) {printf ("fun:%d\ n", a);}voidFUN1 (void(*f) (int),intA) {f (a)

function Pointers: A function pointer is a pointer to a function that represents the address of a function: Such as: Int (*fun) (int *); The above code declares a function pointer fun for an int with an input parameter of int * and returns a value. array of pointers: The pointer array should be more common, as

make it clear that we are calling the FUN1 function.(b) Declare an array of function pointers to hold pointers to the above functions (FUN1, etc.).At this point the main function is implemented as:intMain () {Char*PP ="Hello";CharArr[] ="World";inti =0;Char* (*pfunarr[3])(Char*p,CharA[]); pfunarr[0] = FUN1; pfunarr[1] = fun2; pfunarr[2] = FUN3; for(i=0; i3; i

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 memory, and the use of pointers makes C + + efficient, but pointers are al

A problem raised by a question, first of all, to know [] priority higher than *, title: Char **p,a[6][8]; Ask P=a if the program will cause problems in the future. Why. Direct use of program Description: #include Compile, and then you'll find that pass. Error 1 C2440: "=": Cannot convert from "char [6][8]" to "char * *" So I looked at section 10.5, "c expert programming"-passing a multidimensional array to a function using

These two days have been asked many times about this aspect of the problem, I have been not very understanding, and did not answer well, now to sweep their own blind. //The following are mostly reproduced, mixed with a few personal views, if inappropriate please inform. Array pointers (row pointers)define INT (*p) [n];() high priority, the first explanation is t

Array of pointersAn array of pointers is a special kind of array that holds all the memory addresses of the same data type. The pointer array is defined in the form:Data type * array name [length];For example:const char *c[4] = {"

An array of string pointers, that is, each item in the array is a pointer to a string.Definition: char* s[3]; that is, an array of three pointers, written in this form, can also be better understood, that is, the type of array sto

above problem, I think of the method of using a function pointer array to solve this problem. The concept of the function pointer, as mentioned in the classic tutorial of Mr. Tam Hao's C programming, is not used in most cases and ignores its existence. The function name is actually a pointer to the entry address of the function, but it is different from the normal, such as int*, double* pointers, see the

In response to the above problem, I think of the method of using a function pointer array to solve this problem.The concept of function pointers, mentioned in the classic tutorial of Mr. Tam Hao's C language program, is not used in most cases and ignores its existence.

Let's take a look at the legendary pointer arrays and arrays of pointers today. In the C language, arrays have their own specific types. So what is the type of the array? It is determined by both the element type and the size of the array. For example, the type of int array[5] isInt[5]。In the C language we can rename t
