I'm pretty sure there's a function in the STL that does exactly that

okay thank you)

okay thank you)

Also, don't use macros as inline functions. It can bit you at some point

guys, is there a way to count the length of a string which contain some non-english words

If they are still char symbols this does not change the way length is calculated.

If unicode they need to done same as any other unicode

they are mixed

like " aα？ " total length is 6

Check ascii code range?

I don’t remember, but you can check ascii code of a character in a range

There’s ascii table for that

But I may be incorrect

Any one free for helping me about cmake ?

string..

In other words: We are always confined to a limit. 😅

There is no thing such as unlimited bandwidth, you are always limited (be it 10/100/1000). The caps are always there. 🤔

Welcome, @Y01100000!

Thanks

Any one helping me to use lib please ?

Do anyone have book for STL

What is the best for beginners to learn networking with c/c++

i think u can try to roger some minor problem: simle chat via socket, UDP, TCP

Do anyone have book for STL

C++ fourth edition by bjarne stroustrup

after that move forward advanced problem: such as p2p network, online game like card game

can anyone explain me getchar and putchar

Why it behaves in this way

As getchar takes only one character at a time and putchar display a character

Why it is able to take both characters at the same time(one after another) without printing the first character to sreen then taking the other character and then print the 2nd one to the screen

Thank you so much

🙏

Guys someone suggest learning source for NUMAL ( C library) for computation would be really heloful

*helpful

Or any book, which has written codes for computation using C

Just wanted to confirm whether I got it right, ios_base::sync_with_stdio(false); desynchronizes the c and c++ streams which means that now when I use printf and cout in my cpp code, then they will have their own independent buffers and hence the order in which I see the output in my console may differ in many different runs of the code, although the ordering of different printfs will be in the way they occur in the program and same in case of cout statements but there can be a difference in the order of cout and printf output.

tie in cpp ensures that cout and cin in c++ occur in the order in which they are written otherwise if I do cin.tie(NULL) and cout.tie(NULL) then if this happens -> first cout then cin in my cpp code then it can happen that the program asks me for input and then prints what it want to (using the cout).

In command powercfg /l It will return all power plan GUID If I want to use C++ call windows API, which one I can do that? (There is a limitation of SYSTEM to use command directly) I want to get the list first, then get the description each by each.

yes. but you should avoid using printf and scanf when you do sync_with_stdio(false). use streambufs in combination with fmt::format (std::format in C++20) https://github.com/fmtlib/fmt

and this?

it's not specific to cin and cout. https://en.cppreference.com/w/cpp/io/basic_ios/tie

ok, my example was with doing cin.tie(NULL) and cout.tie(NULL), then the functioning of cin and cout may get un-ordered. What would happen if I only do cin.tie(NULL) and not cout.tie(NULL) or vice-versa?

default is std::cin.tie(std::cout), std::cerr.tie(std::cout) and their wide char counterparts. in the standard there is no requirement for cout.tie() and clog.tie() to be something.

cin.tie(nullptr) makes sense. cout.tie(nullptr) will probably have no effect, test by checking the return value of cout.tie() (no arguments)

can anyone explain me getchar and putchar

Tip: On a Linux terminal type: man 3 getchar 🙂

@RSM15 I know about getchar. Just need to know about The behaviour that instead of taking one character and printing the character (see the code), it takes input at one time only and then prints it

I'll take a look.

I do not see nothing abnormal here. What do you want to do? 🤔

It returns a int which is a multi byte value. If you just want a single character then just cut the unwanted chars.

Try putting this: c = c & (0xFF << (sizeof(int)-1) * 8); below the second c=getchar();

Hi, any idea what's wrong with my switch statement: switch (thiskey) { case 'w': if (y != 1) y--; ; case 'a': if (x != 1) x--; ; case 's': if (y != LINES) y++; ; case 'd': if (x != COLUMNS) x++; ; default: continue; ; } If thiskey == s both the cases 's' and 'd' are executed :-/

you forgot to break;

oh, I mean continue

case X: continue;

or it will iterate through all cases

ahhh. thx

no from me
