The data transfer effect of pointers in arrays

#include <stdio.h>int change (int * b) {int i;for (i=0;i<5;i++) {b[i] = 18;} return 0;} int func (const int * a) {int i;for (i=0;i<5;i++) {//printf ("%d\n", A[i]);//A[i here is equivalent to * (A+i), this is just a habit of people So and so on can fetch all the values of printf ("%d\n", * (A+i));} return 0;} int main (void) {int a[5] = {1,2,3,4,5};//* P =a here the assignment is equivalent to telling the pointer p a[0] address int * p =a;func (p); change (P); func (p); return 0;}
