{ data++;} cout << data1 in main and the value of data1 remains zero why?

you are not increasing the value of data, only moving a pointer

Where does the pointer goes lol

{ data++;} cout << data1 in main and the value of data1 remains zero why?

here’s an example for you: int a = 4; int* b = &a; (*b)++; std::cout << *b; will print 5

{ data++;} cout << data1 in main and the value of data1 remains zero why?

Do you increment a copy maybe?

Wish I had a proper laptop so I could copy paste code

{ data++;} cout << data1 in main and the value of data1 remains zero why?

Because that's UB

hey guys i been learning git these days, but i got a little question here: what's the difference between git rm —cached and git restore —staged? are they both used for remove file from stage area and keep the same file in working directory? i am confused now and i need your help🙏

Hi

Q. Order in which function is called in c/c++ a = F1() * F2() +F3() ;

Q. Order in which function is called in c/c++ a = F1() * F2() +F3() ;

Anybody

Q. Order in which function is called in c/c++ a = F1() * F2() +F3() ;

F1() then F2() then F3()

:D

Thanks!

Welcome

F1() then F2() then F3()

No, in C there is no guarentee that which function is called first.

Order of function evaluation is not defined in C.

No, in C there is no guarentee that which function is called first.

Yes order of function is not defined in C ,but

No, in C there is no guarentee that which function is called first.

Is it right to say that first either F1() or F2() will execute ( F1() , F2() before F3() )

What about c++

Anybody ???

yes

Is it right to say that first either F1() or F2() will execute ( F1() , F2() before F3() )

I think no.

for C is it also right

because of operator priority

operator* has more priority than operator+

because of operator priority

Yes your reason looks valid

I think no.

Why you are saying this ?? What is the reason

What about c++

. Anybody ???

. Anybody ???

operator* has more priority than operator+

Yes but this is valid after function results.

Function evaulation order can be changed by comma operator or maybe paranthesis.

. Anybody ???

F1()*F2() will be evaluated first then +f3()

https://en.cppreference.com/w/c/language/eval_order

Yes but this is valid after function results.

thank you

No, in C there is no guarentee that which function is called first.

but operators

but operators

Yes these are still valid but after result of function or calculated already. Otherwise, what will happened if f3() has dependency on f2()?

still same I guess

f1() f2() f3() which will call f2() as dep

Please read what I shared from cppreference.

who knows how to balance a binary tree?

Yes

Yes

Oh I get it, the same name as before:>

Yes

So wait you remember me?

i am a Chinese who get over the great Chinese firewall，haha

I was in Beijing, local Internet does not provide Google, Telegram etc. But international SIM card provides access to all these services

where i find c standard?

i found standard only in pdf-archivie site

about C90

iirc，c has c99 html standard somewhere

HTML version of C standard draft (n1256.pdf)? https://stackoverflow.com/q/4883212/6949852

First standard is 89/90, right?

where i find c standard?

Google banned you? It's literally first result in Google

Ok, it's a draft of C11, but I don't think it really matters

K&R is first standard

What is a draft? ?

Hello, can someone recommend me a good data structures and algorithm book to begin with.

Im a beginner, i just got through the basics.

Is that okay???

Thank you i will give it a try.

because of operator priority

no. precedence and associativity do not decide order of evaluation

in C f1(), f2(), f3() can be evaluated in any order because there is no sequence point in f1() * f2() + f3()
