C语言:指针和数组记号

对于指向一块堆内存的指针变量,还可以使用数组记号来存储相同类型的几个数据项.
针对于上述,如*(point+i)与point[i]的效果是完全相同的;前者为指针记号,后者为数组记号,两者等价;

示例:

#include <stdio.h>#include <stdlib.h>int main(){    int *point = (int*)malloc(sizeof(int) * 20);    for (int i = 0; i <= 20; i++)    {        *(point + i) = i;//指针记号法        printf("p(%02d)=%02d  Address=0x%08x\t\t", i, *(point + i), point + i);        point[i] = i;//数组记号法        printf("p(%02d)=%02d  Address=0x%08x\n", i, point[i], point + i);    }    return 0;}
