Tell me the error in this code

Does the bitwise xor operator implicitly convert the operands to binary???

Well, how do integers represented in memory?

Hi, im reading a book and in its source i found this simple block: if(p && a > p) do... a is a long, p is a long pointer. I do not understand why p is in and with a. Thanks all

Aditya
can anyone help pls
Aditya
where is the error
Ariana
elaborate more
Ariana
what is the error
Ariana
what do you expect
Aditya
i am making a program on stack
Aditya
i am initialising a pointer sp for the position of stack element
Ariana
also in general trying to golf code using like S1->arr[S1->sp--] just gets confusing, this isn't a code golfing competition
Ariana
dont bother describing what your code does, but what is the error you're getting

https://stackoverflow.com/questions/10036381/arrow-operator-vs-dot-operator
Aditya
But for a struct pointer we declare it by -> symbol
Ariana
is struct stack S1; a pointer to a struct?
Aditya
no
Anonymous
If it is not a pointer?
Aditya
but sp is a pointer which points to the top of stack
Aditya
that's why
Anonymous
Arrow operator applies to a pointer that at the left
Anonymous
Not on the right
Aditya
oh
Anonymous
You need to learn how expressions are evaluated in C and C++
Aditya
ya actually i am reading and today only i read about stack and was stuck in that problem
Aditya
thanks for help
Accel
Use dot operator
Accel
Or in any push pop function pass argument as &S1 and in function def change argument as *S1
Aditya
Ok, thanks

Can you provide full code listing?
Nope
Can you provide full code listing?
void cond(long a, long *p) {
if (p && a > *p)
*p = a;
}
Stay Forward
if checks that p is not NULL and a is greater than *p. It looks like finding maximum of a, and *p
Stay Forward
if code would look like this
if (a > *p)
you will get segfault

It's closed, look with what you develop and look for the app process (the object) functions, normally you have one for it.
