如何打印指针数组地址

如何打印指针数组地址

Answer 1

int *ptr[2]; //指针数组
int p=5, p2=6;
ptr[0] = &p;
ptr[1] = &p2;
cout << *ptr[0] <<endl;//指针数组的值
cout << *ptr[1] << endl;
cout << ptr[0] <<endl;//指针数组地址
cout << ptr[1] << endl;

Answer 2

#include<stdio.h>
void main(){
char *a[2]={"abcd","efg"};//定义并初始化一个字符型指针数组
printf("%d,%d",a[0],a[1]);//输出数组中两个元素地址
}

Answer 3

printf("/u",(unsigned)ptr++);
