Your question doesn't make sense
How do u mean bro?😏

Please 🙏 I just wanna know more...though the question might sound stupid:
What's the difference between gui programming and windows programming?
gui is adding the user interface.. like which someone can tap and an action is executed, the opposite of this is CLI. as for windows programming, I don't know what that is

What do you mean by windows programming?
J
What do you mean by windows programming?
To be sincere, I'm confused to say the only thing I know about it is that it's programming applications for windows..but then I ask how does this relates to software applications...now this is very stupid a question, I know. But would love to see anyone who would assume to answer this newbie who wants to know as he's confused
Andrew
Software and application are sinonyms

Ok...let me reframe the question this way to see if I'll get it. Is microsoft word a GUI application or windows application.....or is it both???...sorry it might look stupid, just try and help me out to clarify

Everything that run on windows is a windows aplication

About is also a gui application, because it appears on the screen

Ok😁....so is it also a gui?
A windows app might be cli. A non
-windows app can have a gui. That is not related

Depends on what you want to learn. As simple but interesting things, you can do a small game, like tic-tac-toe or chess, or you can write a TCP chat (client and server)

hello guys
i would like to to creat a thread function of an int function is it possible or it must absolutly be a void function?

double n,k,sum=0.0;
cin >> n;
for (int i=1; i<=n; i++)
{
cin >> k;
sum += k;
}
cout << fixed << setprecision(12) << sum/n << endl;
Can anybody explain the meaning of
cout << fixed << setprecision(12) << sum/n << endl;

First of all, don't use using namespace std;
std::fixed
https://en.cppreference.com/w/cpp/io/manip/fixed
std::setprecision
https://en.cppreference.com/w/cpp/io/manip/setprecision
std::endl
https://en.cppreference.com/w/cpp/io/manip/endl
It sets the stream to print floats with fixed point notation, with the given precision. Then sends result of sum / n to the stream, then sends std::endl which adds a line break and flushes the output stream.
Look at the examples by the first link.

You can run a nonvoid function in a thread, you just won't have the retval.

ah oké thanks finally i changed things in my function to transforme it to void but initialy it took multiple arguments so for passing multiple arguments into creat_threads i had to creat a struct but the problem now is how to call this struct into my function for taking the arguments
my struct is something like this:
typedef struct a { int v;} aa
and my function:
void func( void *arg){....}

The Chat project is really FUN and full of challenges.

Which thread manager library did you use? normally with the STL Thread you have:
1- std::thread
2- std::future
3- std::packaged_task
4- std::promise
5- std::async
An example with std::future:

I saw that it could work on code blocks so when I tried it it just wouldn't work

It keeps saying
"Expected primary expression before
'int' "

I think I made a dumb mistake though

void numberMaths(int a, int b, char operation)

a = 30;
b = 20;
numberMaths(a, b, '+');

Though if is declared inside the numberMaths function doesn't it make no difference

your variable operation hasn't any values

Hi. Does someone know a program similar to ngrok, but that can use UDP Ports?

guys, Your code is confused. (1) a,b seems like global variable, but you reuse them in function as formal parameters, That's not good. (2) In the main() function, you want to use numberMaths(...), but you give it formal parameters except actual parameter.

I'm still just getting there so I don't really know what the kind of parameters are

Hello.
I am writing code for an Arduino using the great Stack Overflow Driven Development methodology and some random searches.
Now, I have a question that I am not finding an answer because it is a little more of the “how to approach this” kind, rather than “how to do this”.
I have a function that spits a json status out of the IP/Ethernet port.
Now this program has grown to the point where I need this status report to be selective. I therefore plan to add a parameter to the function to tell it which variables to include in its json status report.
The classic way of doing this, I believe, is a bitwise OR of a bunch of bit constants, so that I could for instance call my function like:
statusReport(EthernetClient c, REPORT_TEMP1 | REPORT_TEMP2);
or perhaps:
statusReport(EthernetClient c, REPORT_ALL);
Inside the function I would do something like:
if ( requestedStatus & REPORT_TEMP1 ) { doc[“… } // Add to the json doc the temperature for sensor 1
Now my question is, would this approach be the most recommended for this environment (micro controller, C++) or would any other approach have any advantage in legibility, code size, efficiency or any other I haven’t considered?
Thanks for any inspiration you may want to share.

Hello,
Can anyone suggest me some resource for learn c language as a beginner?
J
Yeah I always try to do it the hardest way to make sure I get it
Doing it the hardest way isn't bad. But when you're a beginner you want to solve the problem first. Then after solving it, go on to see how you can tweak the code to make sure it's more advanced. Though has Bjarne Stroustrup put it: "Complexity is the enemy of maintainability". So do it wisely
