In C, what is the correct syntax for declaring pointers?

I am fighting with the c language. Pointers are new to me, and I think I am getting closer and closer to understanding them.

I have though one questions.

What is the difference between:

int k = 4;
int* pcp = &k;

and

int k = 4;
int *pcp = &k;

I cant seem to find any difference between these declarations of the pointer, is it just syntactical sugar – or is there any difference?

Thanks

Answer 1

There is no difference in those declarations, but there is a difference between the following two declarations:

int* p, p2;  // declares a pointer to int and a regular int 

and:

int *p, *p2; // declares two pointers to int

that might be hidden by your example.

So I prefer the second declaration.
