Hi, can someone give me an idea of how I can make a conversion with 5 choices and the 6th choice is exit. Then in each choice there should be 10 sub-choices that also have conversion
sushi
I wanna use switch case

Assume you declared int* p, and p’s current value is 100. What is p + 1 ?

Hello, someone can help me with compilation of One script written in C? Im using these library (if.h,stdlib.h,tun_if.h). These library are inside /usr/include/linux/ but when i install gcc with buildtools i got error because cant find It (on visual studi community i got no error but i dont know how to create Linux executable). If i write the full directory of these library gcc can found It but i got syntax error, i think because these library have another dipendence behid!

hello everyone , im currently study to OS exam , and i learn about dangling pointers which means that we use a pointer that we already free.
i ask the chatGPT to generate me example and this is the code that he return :
#include <stdlib.h>
int *get_largest(int *arr1, int *arr2) {
if (arr1[0] > arr2[0]) {
return arr1;
} else {
return arr2;
}
}
void dangling_pointer_example() {
int arr1[10] = {0};
int arr2[10] = {1};
int *largest = get_largest(arr1, arr2);
// ...
// arr1 or arr2 is freed, but largest still points to it
free(arr1);
*largest = 5;
}
i think there is no dangling pointer here since the pointer largest is point to the first value of arr2 , which is not freed . am i right?
Dm
What about largest = 5?
If course, In case if you swap values of arrays

Hello. I have a "hello world" conan package, that i compiled using profile for armv7hf. The log shows that i'm create and install package successfully. Then i try use this package in my cmake project and give an error :
/usr/bin/ld: skipping incompatible ...
/usr/bin/ld: cannot find ...
But when i'm install and use this package native, all is good. Does anyone know in which direction I should look for a solution?
klimi
Which book do you recommend?
I don't have any recommendations, I haven't read any c book if anything I read the documentation /the draft. Cppreference might be quite useful as it provides C docs too

Ok thanks

c++ question .... your code subclasses something from libX, overriding some virtual functions, and marks them as override.......
new version of libX comes out
your code now fails because the virtual function you re-implement no longer exist.....
if you remove them, it fails to build against the old libX
do you just remove the override keyword?
the functions dont actually do anything, only exist because the base class was pure abstract and they needed an implementation

Hello Guys! I need to create cross-platform API library for Windows (.dll) and Linux (.so) OS. What I should to do the next? What kind of project I should to be create?
IDCAN
I'm making a loader for plugins. So the most important part of the loader, this is security. Loader client this is like an .NET (Mono) library, but I'd to create a Native cross-platform library for Windows (.dll) and Linux (.so) for soon loading plugins by using PInvoke. The main point of this question, how to create project solution? How to create one solution, one project for those two OS (Windows, Linux)?

Well I wouldn't use such a library to begin with. It doesn't follow the semantic versioning rules. Assuming it did and the bump up was a major version change, I would still not use it because it doesn't respect the interfaces it created. So you can expect non compatible changes in the future from such a library maintainer. In such a case, if the library must be used, i will then fixate on the version that works and not upgrade (i.e fix the library version to a particular release in the build tool). In the meantime, i will also hunt for alternatives or try writing the library from scratch myself.
all good points, however the lib is a OS supplied lib for accessing the calendar. There is no version, no pkg-config i could use to check version, and no #include i could find with version info to #ifdef against. For app to work on the latest release i have to use it, so, the solution i used was to drop 'override' keyword and add 'virtual' keyword. On the old lib, it will still override the functions, and on new it will still build as it doesnt explicitly mark the override

Hello guys I would like to ask how to run 2 while loops simultaneously? Im still new to C++ programming
#include <iostream>
using namespace std;
int main() {
int a,b;
a = 1, b = 0;
while (a <= 10) { // while() loop which keep repeating the output until condition achieved
cout << "Im handsome x" << a << endl;
a += 1; // a = a + 1
}
while (a <= 10) {
b += a; // b = b + a
a += 1;
}
cout << "Sum of 1 to 10 is " << b << endl;
system("pause");
return 0;
}
For the output on the second loop, the output is wrong.

hi guys, so I have a problem with writing on sockets in C. Imagine you want to write two messages (server) to the Client:
write(socket, "HELLO", strlen(HELLO))...;
// Other code (non blocking calls);
write(socket, "BUDDY", strlen(BUDDY))...;
Well, you would expect (Client-side) this to happen:
First read: HELLO
Second read: BUDDY
Instead this happens:
HELLOBUDDY
So the two writes on socket are merged. How can I avoid this?
It does not happen in this case:
write(socket, "HELLO", strlen(HELLO))...;
// Other code, but this time BLOCKING calls, like read(socket, buff, sizeof(buff));
write(socket, "BUDDY", strlen(BUDDY))...;
Or this case:
write(socket, "HELLO", strlen(HELLO))...;
// Other code (non blocking calls);
// sleep(some time);
write(socket, "BUDDY", strlen(BUDDY))...;
But the former rarely occurs (sometimes I just have to send two different things on the net) and the latter won't be accepted by my professor.
I will be thankful for every suggestion!

that's because messages would be stored in receiver's memory . if read slowly or don't read
big
the function read() get messages from host's memory
big
it's network memory

I think LC_ALL and O are some variables, We need more context
Giorgi
Just check what LC_ALL define equals... if 0 then it is same if not, it differs
Ludovic 'Archivist'
0 would be implementation defined
LC_ALL would affect all locale settings
