I have a pointer *p and a reference &s. I would like all the values that s contains to be copied by p. How can I do this?
Need some code example. THX
Your question is a lot less than clear. But for now, I'll give you this:
*p = s;
If this doesn't answer your question, then you need to clarify exactly what you're after.

I want to have a linkedlist for each key in the map in C++.
Yes, std::map<int, std::list<SomeType>> is possible in C++.
Have a look at ideone, which is useful for testing simple things such as this.

For example, I just want it to work in the 1-10 lines, how to do it. A rookie, thanks for help.
You can use narrow-mode, and it will display only the first 10 lines, hiding the rest.

Looking for some opinions on this as it's unclear in reading the C++ 11 documentation.
Absolutely. This takes care of the rule of three for you.

how do v find a value in an integer is garbage or not???
Initialize it at point of declaration, and it can never be garbage.
Pass it to strfry and compare the returned value with the original.
I guess that you mean if a string contains a valid integer. Check out scanf or the stream equivalent of c++, or Boost lexical cast
