I saw a 4 hour full course video in youtube teaching people about C++ Is youtube a good startup for a beginner like me?

You watched freecodecamp??

Yup

Yup

They're great dude :)

In this case no difference. using is preferred since it supports more features and in some cases much more readable (e.g. function pointer aliases)

so do you mean if not for this case they are different too?

like using can be used in various manners like for namespaces, is that what you meant?

For example typedef doesn't work well with templated classes (you can't create aliases with templated parameters), also I remember it works worse with namespaces. I stopped using typedef some years ago in C++, I think syntax of using is also clearer

hmm... thanks

isnt that just template <typename blah> typedef b<blah> x<blah>; ?

isnt that just template <typename blah> typedef b<blah> x<blah>; ?

It won't compile afaik

🙁

🙁

But you can test it, I may be wrong

isnt that just template <typename blah> typedef b<blah> x<blah>; ?

I don't think this will even compile

Hi I'm a 1st year college students. And I'm studying associate in computer technology.

Hoping to learn more here💚

Im otw to a first year in college too😁

I have noticed this a lot in some cpp projects, why do they put two underscores in the beginning and end in their identifier, like __foo__ Is there a reason or just they like it?

Just a convention

"Rule 16 Do not use identifiers which begin with one or two underscores (`_' or `__')." Then, why do they use it in some projects ?

ok, tnx.

“The use of two underscores (`__') in identifiers is reserved for the compiler's internal use according to the ANSI-C standard. Underscores (`_') are often used in names of library functions (such as "_main" and "_exit"). In order to avoid collisions, do not begin an identifier with an underscore.”

ohh, tnx 👍

Yeah. The identifiers with double underscore anywhere are reserved. https://en.cppreference.com/w/cpp/language/identifiers

Does any one know what is Tower of haoin?

How it works?

Does any one know what is Tower of haoin?

It is tower of Hanoi

It is tower of Hanoi

Yes

Do you know much about it?

Do you know how to code it?

Yes

Yes I know but it will be more clear to you if you look out through the videos available on youtube

Using C compiler

Using C compiler

:/

Yes I know but it will be more clear to you if you look out through the videos available on youtube

Yes its good idea.

Using C compiler

U can code it with any compiler only the thing which matter is the logic

Yes

Hey i am beginner of c programming can anyone give me tips?

Hey i am beginner of c programming can anyone give me tips?

try with c++

Thanks rose😊😊😊

See codeforces and solve some. Codes with c++ Learn c++ after c

scanf("%[^\n]s",student[i].name) ; This is incorrect..

See codeforces and solve some. Codes with c++ Learn c++ after c

Yaa but first i have to become good in c

scanf(" %s",&student[i].name) ;

Thank you

❤

What's sapce?

U can use gets() function

Does that program even compile? It didn't compile for me when I tried.

Ohh wait nvm , yes it compiled.

Through gets()

May be indentation error

Okay so which command you used

Please could you stop spamming? Thanks

Please could you stop spamming? Thanks

be like danya offfff

be like danya offfff

What?

scanf(" %s",&student[i].name) ;

Ok , I was wrong...

scanf("%[^\n]s",student[i].name) ; This is incorrect..

It should be %[^\n]% or you can use fgets.

It should be %[^\n]% or you can use fgets.

No all this I tried

No all this I tried

No , I just now tried now works for string with spaces.

It should be %[^\n]% or you can use fgets.

ok wait

no it doesnt

If you want to load the whole line you can use other functions for that...

what others?

Like fgets

no it doesnt

Weird.

I'll pass

I'll pass

Yaa but first i have to become good in c

No you get better only by using c

No, no... You didn't get me, I'm not looking into it

No, no... You didn't get me, I'm not looking into it

you broke his heart

ok wait

Hmm , maybe why not just have something like, struct student_info { char firstname[27]; char lastname[27]; int roll_no; int submarks[5]; }; scanf("%s%s",student[i].firstname, student[i].lastname); Most online answers suggested fgets and something like %[^\n]s which you said didn't work for you..

What the fuck

Don't give bullshit advices please

1. Codeforces doesn't teach C++ 2. To learn C++ you don't have to learn C first. Learning C first is basically useless and even harmful.

If you don't know what C++ is and how to teach it — keep your mouth shut
