All programming languages I am familiar to (C/C++, Java, C#, Objective C) accept both notations. So I want to 开发者_JAVA百科know which is semantically correct: Object* myObj or Object *myObj?

---

Well, it depends. Both are correct but I generally use the Object*, because the pointer itself can be considered a type and it is more readable.

But there is a problem with that. The pointer in C, by real, is just a modification of a type, and not a real type. If you declare multiple variables in one single line as this:

Object *a, b;

You will have a as a pointer to Object and b as one instance of Object, so I imagine that the correct way is to put the pointer with the variable.

Which is semantically correct?

Semantically they are identical. Therefore which you use is a matter of taste.

---

Which taste should you prefer? Well, you can write object* a, b and think that you have declared two pointers. Of course you have not, you have declared a to be a pointer and b as an object.

So you should certainly prefer object *a, b to object* a, b. However, I believe it is better still to have a single line for each variable declaration:

object *a;
object b;

This approach has no scope for confusion and is recommended by many coding style guidelines.
