int _tmain(int argc, _TCHAR* argv[])
{
	int x=10;
	int y=20;
	int *i=&x;	//相当于int *i; i=&x; 因为＝比*的优先级高

	cout << "x:"<<x<<endl;		//x的值
	cout << "&x:"<<&x<<endl;	//x变量的地址
	cout << "i:"<<i<<endl;		//指针型变量i指向的地址
	cout << "*i:"<<*i<<endl;	//指针型变量i指向的地址的值
	cout << "&i:"<<&i<<endl;	//指针型变量i自已的地址
	cout <<endl;

	(*i)++;
	cout << "改变指针所指变量的值"<<endl;

	cout << "y:"<<y<<endl;
