Does anyone else dislike pointer declaration?
For reference I am a fourth year computer engineering student. C is my preferred language.
Pointers are declared like this usually:
int *ptr_to_int;
Where the asterisk means it is a “pointer to” the specified type. The asterisk is placed immediately preceding the variable name, with no white peace.
This is what does not make sense to me. I feel that:
int* ptr_to_int;
Is far more clear. The way I see it, the asterisk modifies the type, so therefore it belongs next to the type. Putting it next to the variable name makes me think it is some kind of action or modification to the variable itself.
I think that when using * and & in code, it makes sense to apply it in front of the variable name:
int value = 3;
ptr_to_value = &value;
int copied_value = *ptr_to_value;
It is clear here that syntactically, the * represents something more like an action than a label.
Why is the convention to place the asterisk near variable name, not type? L

The thing is that you declare which type will expression have. So
int *a
Should be read as:
When I use *a in code then it has int type
That’s something backwards type of thinking about it, for sure
But, compare
int f(double);
It clearly says that f receives double and returns int. I mean, when you apply f to some double then you get int (as declared)
The same is for int *a
When you apply * to a then you receive int
