It’s a waste of memory to allocate each chunk of memory to 46bytes though especially since most words are around 5 characters long, you could count the length of the word then allocate memory to fit the size of that word plus a null
That is also quite wasteful. It is simpler to actually copy the entire string and allocate an array of offsets, and add a null in the middle of the allocated string where the space was as you read it

Memcpy is also more efficient at copying larges swathes like that
Ludovic 'Archivist'
That will avoid all inefficiencies related to allocating small amounts of memory
Spirit
Yeah
Spirit
Never thought of that
Ludovic 'Archivist'
You will, however, not be able to free the little strings, and will need to free the large one at once, so less memory efficient long term, but also causing less memory fragmentation

Trade-offs yada yada

Still smart way of looking at it

It depends on you, for me it took 2 weeks, because I knew few languages before that like Kotlin and Python. Absolute Beginners take more time.

Hey, any body here started using c++20 modules ? On Linux with either gcc or clang
I followed a lot of blogs on the same but unable to make it work
itsmanjeet
Same guide work for msvc not for gcc or clang
Ananth
gcc/clang has limited support for modules.
Ananth
gcc has slightly more features than clang. you can check the cpp comparison chart
Ananth
I have tried a few basic examples and got them working. it is still very much work in progress.
Ananth
I dont use windows or msvc, so cant compare.

What error? Did you use -std=c++20 flag?

I tried with cmake as per the
add_library(mylib)
target_sources(mylib
PUBLIC
FILE_SET CXX_MODULES FILES
file1.cppm file2.cppm)
add_executable(myexec main.cpp)
target_link_libraries(myexec PRIVATE mylib)

I want to make screen break project in c++ which things I need to know for this
Tronald
Qyu=*createQueue(Qyu_size+1);
so this function would malloc a structure Qyu
if(enqueue(&Qyu, element)) printf("Enqueue Successful\n");
so if I pass addresses to the function within an if statements, will the changes made by the function persist? in C

If the function makes any changes and the function is executed, then yes, the changes will persist
Tronald

does using or not using malloc have any effect?
