指针的指针

#include <iostream>
using namespace std;

int main()
{
int a = 5;
int *b = &a;
int **c = &b;

cout << "a:\t" << a << endl;
cout << "&a:\t" << &a << endl;

cout << "b:\t" << b << endl;
cout << "*b:\t" << *b << endl;
cout << "&b:\t" << &b << endl;

cout << "c:\t" << c << endl;
cout << "*c:\t" << *c << endl;
cout << "**c:\t" << **c << endl;

system("pause");
return 0;
