You want to know the meaning of cout or whole code?

Answer 2

{
int *p = new int; // request memory
*p = 5; // store value

delete p; // free up the memory
// now p is a dangling pointer

p = new int; // reuse for a new address
*p=20;
cout<<&p<<endl; // address of p
cout<<*&p<<endl; // value (a pointer) at address p
cout<<p<<endl; // value of p (an address)
cout<<**&p<<endl; // value (an int) at a ptr value at the address of p
cout<<*p<<endl; // value at p pointer
return 0;
}
