I'm having problem with c
Consider reading a book at first and do some programming challenges for beginners after that

Does c++ is just Object orientated add-on on C?
Ilya
It's guide of c++
C is included in C++, if you study c++ c will be addressed as bonus.
If you study C, you will just waste at least half of time

How I can difference between two then?
Ilya
C++ and C
Nameful
C++ isn't entirely a superset of C
Nameful
I would argue it is important, especially if you're used to doing OOP C++ writing C will require learning new things
Ilya
There is a very good book
By Harbison and Steel called annotated C, you can read it after studying C++ and you will definitely know pure C , too

This is function call operator, not "less"

Any examples?
E.g
struct Ds {
int x;
bool operator <(const Ds& rhs) const {
return this->x < rhs.x;
}
}

Waiting for operator<=> duh

Can anyone tell me which coding language Can I use to make a pdf editor
since this is c/c++ group, you can use that

yes

Can anyone tell me which coding language Can I use to make a pdf editor
PDF is a printable form, why should it be edited?

Hi, I am trying to send a Telegram message using C. I have a piece of code provided by the supplier of a NRF9160 microcontroller that is programmed in C. They provide some code to make an HTTP GET request. However, it is a simple example and it is not specified how to pass arguments or parameters. I have this line
char send_buf[] =
"GET / HTTP/1.1\r\nHost: www.google.com:80\r\nConnection: close\r\n\r\n";
that I understand that it is where the request is created.(I am quite new with C and I am more familiar with Python.)
Taking that line as base how I can specify some arguments for example arg1=MYARG1 and arg2=MYARG2 to make the request?
Thanks a lot, any help is welcomed.

for get parameters specify them in the first line like GET /?a=3;b=5 HTTP..., for post add a Content-Type header, set it to application/x-www-form-urlencoded, a Content-Length header, then at the end of the request add the post parameters in the same format as the get parameters
