指向指针的指针变量

#include<iostream>

using namespace std;

int main()
{
//声明指针数组
const char *colors[] = { "red","blue","yellow","green" };

//指向指针的指针变量
const char **pt;
 
//通过指向指针的变量访问其指向的内容
pt = colors;
for (int i = 0; i <= 3; i++)
{
	cout << "pt = " << pt << endl;
	cout << "*pt = " << *pt << endl;
	cout << "**pt = " <<**pt << endl;
	pt++;
}
 
return 0;
