Hello
Can someone help me with this?
Anonymous
I read Non static member initialization is introduced in c++11 which allows to initialize directly like
class A{
int data{1};
};
So was this an error to use
class A{
int data =1;
};
Before c++11?
Are both codes refer the same feature introduced in c++11

Hello there.
I'm doing a cache simulator in C. Could someone tell me how do I simulate the access using an associative cache with write-throught. Check if the address is in the cache (separate file) and if not, update the cache. Update hit or miss counters. Hit =on chace, MISS = not in cache

The only advice to you is upload source codes of the tutorials and provide links in description

what is the difference two function call?
scanf(“%c”, &ch);
scanf(“ %c”, &ch);
Emir

scanf(“%c”, &ch);
scanf(“ %c”, &ch);
The first call is need to fflush(stdin) before i call, the other one is don’t need to fflush stdin, why is that?

I want to know how I can embed a python file into c/c++ program. I just want the file to exist in the c/c++, it can be transferred to other devices as well.
Emir
So i want to get string from file, etc the string is : blabla\n
how can i that string include new line character
Anonymous
Emir
fscanf is just getting blabla not New line character
Emir
But i dont know which index has \n char, i have a dynamic string array(each string maks 40 byte) and im reading file to dynamic array, when i do that \n chars are gone
Anonymous
I don't think that's a problem
Emir
bla bla
bla2 bla3
->bla bla bla2 bla3
Anonymous
std::string str;
std::getline(std::cin, str);
str += '\n';
Emir
how can i do that? how include \n to string that i dont know which string has \n char
Anonymous
I know
Emir
std::string str;
std::getline(std::cin, str);
str += '\n';
i dont want read line by line, i want word by word, my base question is change a string in the file another string
file is
bla bla
bla bla
input bla, aaaaa
output file
aaaaa aaaaa aaaaa aaaaa
Emir
So i have to read word by word
Emir
i want to change original file, wait a second i will send my algorithm
Emir
https://paste.ubuntu.com/p/xccTxv8TWF/
Here is my algorithm, dizi iz an dynamic array that each elements are 40 bytes string
Emir
fscanf(fptr, "%s", &kelime);
if right byte of str is a new line character i want to include that
Emir
i think that is not the important point because this is first class homework, it still wrong i know but i can each string 100 bytes, it will not problem for me. The problem is how i can (if there is) include the new line character
Emir
okay i will try this, thanks a lot
Nameful
Would the instructions be cached if I repeatedly called the function in a simple loop?
Nameful
Okay, thank you. I'm very new to taking cache into consideration when writing code, but it's very interesting.

Hi, I was trying to use C++ library in my project. I used Cmake gui. First I clicked configuration, then generate and opened project in Visual Studio. Then I builded that project idk why exactly. But it takes a lot of time and haven't done yet and the file that project located is exponentially growing. So, my question is why is that happening and is there any resource that I can read in order to know what's happening. I'm new at C++
Harsh
make -j$(nproc --all)
Harsh
It'll show the object files being made

Use vcpkg to manage your dependencies
Emir
So what exactly don't you understand?
my code is just main function it doesn’t need any object file
int main()
{
}
My code is this why isnt that linking?

oh thank you, I was struggling with this for hours.
There are two popular package managers for C++ — conan and vcpkg. Your library is hosted at vcpkg.

From where can I learn about these packages generally like how to include libraries famous package managers similar things for software development. Because books I read currenty doesn't mention about these things

what is the crt0.o ?
Emir

when are static member functions of class templates instantiated? when the class itself is instantiated? or when the function is called?
