Are you sure you want to go with incorrect code in the first place?

Is this the new standard?emm，just {} because the underlying initialization is 0 by default?
C++11, uniform initialization
Pol
I wish I could find something more elegant, but I guess I will need more time for that.

Pol
I think I have to build the local item to concat and allocate the array inside the for loop.
Pol
So I will need a bit more time to do.

OK，i know

Why not just use C++?
Pol
Because I can only use C right now. C++ is not in the scope.

It's not a new standard, but good programming practices are required. Once {} already assigns 0, no longer required to put {0} or could be <type><name variable> <value> Example: int a =0; int a{}; int array={}; It's just an idea not to be wrong, but it's not necessary

Is this a university program or what?

Good for you! It's never to late

Found a nice solution !

char* item = NULL;
size_t item_length = 0;
for (int i = 0; i < size; i++) {
item_length = snprintf(NULL, 0, "%i", arr[i]);
if (i < size - 1) {
item_length += strlen(separator);
}
item = (char*) malloc(item_length);
sprintf(item, "%d%s", arr[i], (i < size - 1) ? separator : "");
strcat(str, item);
}
Pol
A bit verbose, but this is definitely better I think.
Pol
I can even remove the strlen(separator) out of the for loop.
Pol
Ok I'll continue tonight, thanks for unblocking me Danya !
\Device\NUL
char* item = NULL;
size_t item_length = 0;
for (int i = 0; i < size; i++) {
item_length = snprintf(NULL, 0, "%i", arr[i]);
if (i < size - 1) {
item_length += strlen(separator);
}
item = (char*) malloc(item_length);
sprintf(item, "%d%s", arr[i], (i < size - 1) ? separator : "");
strcat(str, item);
}
malloc could be failed, you shold add NULL checking if malloc failed to allocate memory

You can use sdl2 with your C++ program. Just don't forget to include SDL2 headers.
Iknow only c not c++ thats the problem
Fetheddine
Like you can say i want. To make real project in c what can ido

You can create a simple shell

You said you want to code in C++ right? Or you want to use C? Either way, since SDL2 is a C library, you can use it in C and C++.

Fetheddine
In the course iwas following it was sdl nd its compatible with c but now its sdl2 nd it uses c++
Fetheddine
While i search in google they say you can make everything in c. But how can i do it.
Fetheddine
Maybe just a little game in a window or idk i juste want to work on a window programm not a console one

Iwant to code in c
Download SDL2 lib and headers from SDL2 website. Import(include) the header files in your C project. Call the handlers to SDL2 library in your main() in C. When compiling, don't forget to link SDL2 libs against your C program.

Even though the example has .cc(c++) extension, it is C styled C++. (for example, it uses printf instead of c++ specific cout and etc...). You can copy it to your main.c file, compile it and run it as a C program since it uses C functions.

C? You can use it for system programming, create drivers, develop kernels, emulation, literally anything. Same can be said about C++ or other compiled, programming languages(w/o Garbage collector)

u can went to github to find a suitable small project

But in fact, it's hard to find

So i have to go to c++ then

Thats where i can do complete desktop app

hhh,maybe, but many beginners don't know how to do it at the beginning
