I was just browsing through a few C exercises, came across this:

The following code:


void main()
{
int const * p=5;
printf("%d",++(*p));
}

Thanks a lot for the help.

Thats not homework.. I asked these questions because i have no clue as to what the answer is. If i knew so, i wouldnt be asking.

But then, to elaborate on them more..

1. Can a pointer be...

I was going through a few C quizzes and was quite baffled by the amount of questions i could answer correctly. Never thought C was such a confusing language !

Well, anyway... here are some doubts...

I have absolutely no clue as to how it works, but i cant seem to find any resources to learn basics about O(log n) O(n) etc.. etc...

Anybody care to help ?

Well. thanks a ton !

All those explanations really helped. Thanks again.

Is this allowed ? I thought it isnt.

What is the difference between *start and *p ???

Im asking this because :

we create *p by :


struct node *p = malloc(sizeof(node));

Well, that creates another problem for me.

So, p points to currently allocated node struct memory.
Suppose that memory is 1776.

If the start pointer of linked list is *start pointing to first...

I was starting out with data structures, but had these few doubts:


struct node {
int x;
node *next;
};

Now, If we have a pointer *p such that

lol, that cracked me up.

Well, your explanation helped ! Thanks a ton !

Is there anything wrong with this :

I was trying to pass addresses of 2 variables to a function, but compiler is giving me an error.


add(&array1,&num2);

Anything wrong with the above code ?

Error is :

forgive me for such a n00b question but I have seen this symbol quite alot of times studying data structures n stuff... just didnt find the proper reference anywhere.

what does " -> " mean ?? can...
