Understanding memory allocation

I'm new to c++ but I do have a programming background.
I understand that there are three ways of allocating memory: on the stack statically, on the stack dynamically and on the heap dynamically. I just don't understand which one will take place with the following statements and how to delete memory used by them:

Code:

---

class MyClass1
{
      int intArray[10];
      ...
}

class MyClass2
{
      int* intArray;
      ...
}

class MyClass3
{
      OtherClass anotherObject;
      ...
}

class MyClass4
{
      OtherClass* anotherObject;
      ...
      public:
          void TestMethod();
}

void MyClass4::TestMethod()
{
    OtherClass* localObject = new OtherClass;
}

Thanks in advance.
Cheers.
