yep address was from SDK funktions of game. What i need to do if i want to get another address of like this but not from UWorld, from another class. What I need to focus to get the address I want?

But put a semi colon after u input name

Bro can u show me, how to import my function if i send u full of the code in zip file. Im stucking with this problem for a week.

hello everyone hope you are all right ,
can you suggest me some idea project for C/C++ langage ??? any idea all welcomed

I'm sorry I have a question typedef it is C or C++?Because I need only C

typedef can be used in C or C++, but in C++ there are better alternatives (using), and in modern C++ typedef is very rarely used.
Also in C++ you don't have to use typedef to declare structs.

Can cmake subprojects reference the header files of subprojects？
Anonymous
Can cmake subprojects reference the header files of subprojects？
When you say subprojects, do you mean something that you add using add_subdirectory? Sub projects could mean a lot of things like independent projects brought in using git submodule or a nested project structure with a CMakeLists.txt file with a project command or just a nested structure brought in using add_subdirectory. Which of these do you mean?

This is not the right way to do things even it works for you. Your projects A and B have a CMakeLists.txt file with a project command. Ideally they should be treated like dependencies and not sub projects.
To include header files from dependencies, the recommended way in Modern CMake is to create an imported target with transitive dependencies that get passed on to targets that depend on them.
So your A and B projects can set target_include_directories with either PUBLIC or INTERFACE property depending on whether they themselves use that include directory or whether they just want downstream targets to use that include directory.
Now main can use target_link_libraries to add a dependency to this imported target and automatically bring in the include_directories dependency.
Aurora
Ok let me try
Aurora
Bro. I need B sub include include A header
Anonymous
Bro. I need B sub include include A header
Well set up an INTERFACE library in A sub that sets target_include_directories to the include headers path in A. Make this interface library a dependency for B Sub. What is stopping you from doing this?
But to be honest, I still don't have a clear picture of your dependency graph. If you make your dependency graph look like sphagetti, you are going to have trouble later on when your code grows. Check to see if B Sub needs to have a dependency on A Sub or if you can remove the common parts into something like a utils library which A Sub and B Sub can both depend on rather than B Sub depending on A Sub.

We should add godbolt.org to these

Added godbolt and wandbox
Not sure about the order, I would start with the simplest one from the list, not sure if everyone can figure out how to share code from godbolt

Done. But TBH, figuring out how to use a site like GodBolt should be easier when compared to learning C/C++.

Hello guys👋🏼👋🏼👋🏼
Please help🙏🙏🙏
Develop an src/edit.sh script for replacing substrings in text files. The input data must include the path to the file (relative to the root directory), the string to be replaced, and the replacement itself (as a string). The information on each change must be added to the log: src/files.log in the format described in the previous quest. Pay attention to the processing of edge cases.

You can add any folder as include directory, then in tag folder add folder mylib and add headers of your "library" there.
Then it depends what you want to do with it, you can compile cpp files of that "library" as a static library and link it, or just compile them together with your project. Or you can do header-only library if you use C++ and don't mind long compilation times :D

I haven't seen your code, but you need to insure you never use uninitialized pointers, don't try to change constants, don't access memory after it has been deleted/freed, check your pointer math that it's correct and you don't read for example out of bounds of arrays, don't delete memory twice, and maybe some other things that I don't remember
Pavel
int n,s;
cin>>n;
int ar[20];
for (int i=0;i<n;i++){
       cin>>ar[i];
       s=s+ar[i];
}
cout<<s;
Are you sure n can never be greater than 20?
Also your s variable is not initialized.
Divyanshi
Are you sure n can never be greater than 20?

It can be....
Oh right i forgot to write it here

Otherwise I have written that in the code

Pavel

So then it's reading out of bounds of the array

Depends on how you want your program to react, should it be able to process bigger amounts of elements?

I think it should...
Pavel

Then instead of using fixed size array you can allocate it dynamically and then delete it later.
Or, because you're writing in C++ you can use std::vector that will do that for you.
int n;
int s = 0;
cin>>n;
vector<int> ar;
ar.reserve(n); // just to make it a bit faster
for (int i=0;i<n;i++){
int value;
cin>>value;
arr.push_back(value);
s += ar.back();
}
cout<<s;
Pavel

However, if you just want to calculate the sum, you don't need the array
