Thread: Difference b/w int* p1 and int *p1

Hello All ,
is there difference between int* p1 and int *p1 .

Code:

 :
           int main()
{
	int x =3;
	int* p1;
	int *p2;
	p1 = &x;

	p2 = &x;
	printf("%d\n",*p1);
                printf("%d\n",*p2);
	return 0;
}

Code doesn't have any problem.
--------------------------------------------------------

whether really it makes any difference with below ?
int *p1;
int* p1;

No. It's just a matter of style.

Edit: I'm too slow! See above FAQ entry.

No. However, I have heard in a book that the generally accepted method is to do:

Code:

int *ip;

Because if you were to do

Code:

int* ip1, ip2, ip3

Then you would have the unexpected outcome of ip2 and ip3 being plain int's. Not pointers to integers.

To stop some people from pestering me about "you should do it this way or that" I've done the unthinkable:

Code:

int * p;

That's right, space on BOTH sides! The revolution starts now.

OMG!!! This is crazy!!...lol

I usually do int* p

int* - just means "integer pointer" to me.

rather than

int *p - "interger type pointer p" which just doesnt make any sense

yeah but
int* p, q;
would q be an integer pointer? no.
so it's
int *p, q;

I would use something like this:
int* var;
int var1, *var2, var3;

Simply put, when there's a single variable the asterisk stays with the type. This is especially useful for function declarations since compilers usually type their errors in the same fashion.

I don't know - I think his intentions are clear enough. I mean, he prefixed a 'p' to the new type. Anybody should easily be able to see what he intended there, even if the code is a few thousand lines long.
