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.

how to put a counter in constructor??
if you want to count the number of created objects, you can use a static (class) variable
class CountingClass {
private:
static int count;
public:
CountingClass() {
++CountingClass::count;
}
};
