assianing value of pointer

is it a valid statement if no y
int *p=&x, x;

 

[James Kuyper]

is it a valid statement if no y

What does 'y' have to do with it?

int *p=&x, x;

First of all, that's a pair of declarations, it's not a statement.
Secondly, unless there's prior declaration of x that will end up being
hidden by this one, you're trying to use 'x' before it's been declared.
That's easily fixed:

int x, *p=&x;

I think the OP meant:

Is it a valid statement? If not, why?

Note to vj: Please don't use silly abbreviations like 'y' for "why".

First of all, that's a pair of declarations, it's not a statement.
Secondly, unless there's prior declaration of x that will end up being
hidden by this one, you're trying to use 'x' before it's been declared.
That's easily fixed:

int x, *p=&x;

Or, even better:

int x;
int *p = &x;

What does 'y' have to do with it?

int *p=&x, x;

First of all, that's a pair of declarations, [snip]

Actually it's one declaration, with two declarators, and
two identifiers being declared.
