to none zero value

to none zero value

Yaa give

Priori

But the array elements are getting different value

Pooja

Example: float x; x=3.14; int y; y= (int)x; printf(“%d”, y); Output: 3

What does y=(int) x; will do?

Riya

It will give only the int part in x

Riya

What does y=(int) x; will do?

(int)3.14 is 3

Pooja

Okay.. Thanks

Hey, I'm reading a c book and I got a little confused with the get char and EOF, can someone maybe explain it to me better? 🙈 Exelmple.. main() { int c; while ((c = getchar()) != EOF) putchar(c); }

ברני

Oh and putchar..

Shuntaro Chishiya

Hey guys can anyone help me how to hide PID ?

Shuntaro Chishiya

Of any particular data

Shuntaro Chishiya

Or app

Ammar

Process ID?

Ammar

I don't think you can, unless you rework the kernel.

Shuntaro Chishiya

Process ID?

Ya process id

Shuntaro Chishiya

I don't think you can, unless you rework the kernel.

I have to rework kernel ?

Dima

It’s not possible unless you rework kernel

Ammar

I have to rework kernel ?

Yes, every process is managed in struct task_struct.

someone who can face any of these problems (1586,1658 in acm.timus) and share how solved it step by step? as a guide to understand how to apply the dp.

Hi. The C++ international standard document that I've found on the internet states that all assignments "return an lvalue reffering to the left operand". I've read on cppreference that an lvalue is a type of a glvalue, which is "an expression whose evaluation determines the identity of an object ..." I'm confused. What does it mean for an expression to return an expression? To my current knowledge, assignments with default types as the operands return a reference to the variable that is being assigned to, but I'm new to the concept of lvalue. Can anyone shed some light on this?

Foxner

Also, is it correct to say that expressions like x = a and ++x return a reference to x?
