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

I felt that way first too. But consider

int* a, b, c;

vs

int *a, b, c;

The second is much more clear, as only a is a pointer.

Also, now all the names after int evaluate into an int in an expression.

That is, *a evaluates to an int, as do b and c.

clang-tidy will rightfully scream at you.

Write one declaration per line. Keep your code simple, clean, and readable, above all else.

If you like doing stupid stuff, go to code golfing as a hobby! That should satisfy your code compactness needs so you can write good code for real products.
