本文通过一个简单的C++示例程序详细介绍了如何使用多重指针来操作内存地址，并展示了如何打印变量及其地址，帮助读者更好地理解指针的概念。
int var = 5;
int *p = &var;int **s;
s = &p;
cout<<"指针S的地址："<<&s<<" ";
cout<<"\n";cout<<var<<" ";
cout<<&var<<" ";
cout<<"\n";
cout<<**s<<" ";
cout<<*s<<" ";
cout<<&(**s)<<" ";
cout<<"\n";
cout<<*p<<" ";
cout<<&p<<" ";
cout<<&(*s)<<" ";
cout<<*(&s)<<" ";
