You don't need to create type ourClassPtrType to dynamically allocate an object of class ourClass.

It is usually done like this:

ourClass {
     // definition of your class.
};

int main() {
...
ourClass* ourClassPtr = new ourClass();
// now ourClassPtr is a pointer to a dynamically allocated object of your class.
}

If you realy need type ourClassPtrType, you can do same thing:

ourClass {
      // definition of your class.
};

typedef ourClass* ourClassPtrType;

int main() {
     ourClassPtrType ourClassPtr = new ourClass();
// now ourClassPtr is a pointer to a dynamically allocated object of your class.
}

You don't need the parentheses on the new expression.

ourClass* ourClassPtr = new ourClass();
ourClass* ourClassPtr = new ourClass;

These both do the same thing, so the lack of parentheses was not a flaw in the code in the question.
