C/C++对数组的引用——指向指针的指针和指针引用

http://blog.csdn.net/anye3000/article/details/6578262

#include <iostream>
using namespace std; 


void main()
{
	int a = 10;
	int **pTest = new int*;
	int *pSec = &a;
	pTest = &pSec;
	*pTest = pSec;
	cout<<*pTest<<endl;
	cout<<pSec<<endl;
	cout<<**pTest<<endl;

	//修改一个指针的值
	*pSec = 100;
	cout<<**pTest<<endl;


	//测试引用
	int &b = a;
	cout<<b<<endl;
	b = 1000;
	cout<<a<<' '<<b<<endl;
	//int *&pRef = &a;//error.
	int*pRef = &a;
	int* &pNef = pRef;
	//修改变量a的值
	*pRef = 2000;//通过指针修改a的值
	cout<<a<<endl; //a的值被修改
	*pNef = 3000;
	cout<<a<<endl;//通过指针的引用修改变量a的值
	cout<<pRef<<endl;
}

 数组的引用和指针的引用非常类似,因为数组名本身也是一个地址;对二维数组而言,我们传参的方式有三种
