Correct use of std::map as class member

Question

In the past I always created a map like this:

class TestClass
{
    private:
        std::map<int,int> *mapA;
};

TestClass::TestClass
{
    mapA = new std::map<int,int>();
}

TestClass::~TestClass
{
    mapA->clear(); // not necessary
    delete mapA;
}

So, now I read all over the place at Stackoverflow: avoid pointers as often as possible

Currently I want to create the map without pointer and new (no need to delete the object by myself and less danger of getting some memory leak)!

class TestClass
{
    public:
        TestClass() : mapA() // this is also needed?
        {};
    private:
        std::map<int,int> mapA;
};

Any further steps for correct creation of the map necessary?

Thanks for any help and/or clarification!

Nope that's it, and you don't need to explicitly initialize it in the constructor.
