指针学习（二）指针与数组

#include <iostream>
int main()
{
	using namespace std;
	double wages[3]={10000.0,20000.0,30000.0};
	short stacks[3]={3,2,1};

	//取得内存地址
	double * pw=wages;//double * pw= &wages[0];与这种写法是相同的
	short * ps=&stacks[0];

	cout<<"pw= "<<pw<<",*pw= "<<*pw<<endl;
	pw=pw+1;
	cout<<"Add 1 to the pw pionter:\n";
	cout<<"pw= "<<pw<<",*pw= "<<*pw<<endl;
	cout<<"ps= "<<ps<<",*ps= "<<*ps<<endl;
	ps=ps+1;
	cout<<"Add 1 to the ps pionter:\n";
	cout<<"ps= "<<ps<<",*ps= "<<*ps<<endl;

	cout<<"access two elements with array notation\n";
	cout<<"stacks[0]="<<stacks[0]<<",stacks[1]="<<stacks[1]<<endl;
	cout<<"access two elements with array notation\n";
	cout<<"*stacks="<<*stacks<<",*(stacks+1)="<<*(stacks+1)<<endl;

	cout<<sizeof(wages)<<"= size of wages array\n";//数组实际长度
	cout<<sizeof(pw)<<"=size of pw pointer \n";//地址长度
	return 0;
}
