指针变量引用

#include<iostream>
using namespace std;

int main()
{
	int a = 1;
	int b = 10;
	int* p = &a;      //指针变量p指向a
	int* &pa = p;      //pa是p的指针引用

	(*pa)++;        //pa指针指向的内容+1，pa是p的引用，p指向的内容+1，即a+1
	cout << "a=" << a << endl;        //a=2
	cout << "b=" << b << endl;        
	cout << "*p=" << *p << endl;        //*p=a

	pa = &b;           //pa指向b
	(*pa)++;           //b+1
	cout << "a=" << a << endl;        
	cout << "b=" << b << endl;       
	cout << "*p=" << *p << endl;         //*p=b

    return 0;
}
