😂I've seen many beginners of C + + use C style when writing programs，the only possible change is that printf becomes STD:: out

such as struct，Instead of using classes, they use function methods externally, just like C

Conclusion my problem isnt here my problem is that course is old and many fonctions does not exist anymore so i need a documentation on sdl2 in c language

It seems that it is indeed a C-style API, but it is not guaranteed that what I see is backward

Like I said, it is literally copy pasting library, importing headers and writing the Code. (Since the C++ code in most tutorials for SDL2 are C styled since SDL2 is a C API) For example, main.c // SDL2 Hello, World! // This should display a white screen for 2 seconds // compile with: clang main.cpp -o hello_sdl2 -lSDL2 // run with: ./hello_sdl2 #include <SDL2/SDL.h> #include <stdio.h> #define SCREEN_WIDTH 640 #define SCREEN_HEIGHT 480 int main(int argc, char* args[]){ SDL_Window* window = NULL; SDL_Surface* screenSurface = NULL; if (SDL_Init(SDL_INIT_VIDEO) < 0) { fprintf(stderr, "could not initialize sdl2: %s\n", SDL_GetError()); return 1; } window = SDL_CreateWindow( "hello_sdl2", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, SCREEN_WIDTH, SCREEN_HEIGHT, SDL_WINDOW_SHOWN ); if (window == NULL) { fprintf(stderr, "could not create window: %s\n", SDL_GetError()); return 1; } screenSurface = SDL_GetWindowSurface(window); SDL_FillRect(screenSurface, NULL, SDL_MapRGB(screenSurface->format, 0xFF, 0xFF, 0xFF)); SDL_UpdateWindowSurface(window); SDL_Delay(2000); SDL_DestroyWindow(window); SDL_Quit(); return 0;} Here, I just changed main.cc to main.c since the tutorial literally uses C styled Cpp or basically a C program. https://gist.github.com/fschr/92958222e35a823e738bb181fe045274

SDL2 is written in C.

Yeah but its changed to be more compatible with c++

Like I said before. It is a C library, written in C. C++ can use this library because C++ supports C styled programming and iirc, there are no native bindings for SDL2 to C++. A pure C game engine using SDL2 for windowing https://github.com/eduard-permyakov/permafrost-engine

Yep but now theyre devloping it to be more compatible with c++

🤦I used that library in the past(maybe 6 months before). I didn't use it with C or C++. I used it with Zig(A programming language like C, made to replace C). How? Creating wrappers around C API. (Or TBN, it is very much compatible with C because it is made in C so that other languages can create wrappers). And like I said before, C++ can call C library without any additional tweaking. That is why there is no SDL2-C++ with classes and namespaces or other things.

Wdymn by creating wrappers

codes that literally wrap around other program components. pub fn init(flags: InitFlags) !void { if (c.SDL_Init(flags.as_u32()) < 0) return makeError(); } Now, if in my program, I can just do init(_) instead of doing all those stuffs in the init()//Since we are calling a function from another programming language. (Consider it as it is to make sure calls are more native to the programming language I am using)

hello, i havent studied object oriented yet and i need help in changing from objects and classes to functions without classes in c++ can anyone help me in pm?

You ask just for ask? First learn how to Google information. So many books for beginners.

I think this is a good solution

You want to turn it into the form of oop?

there are only members in struct

Is that the only thing you're allowed to say

Looking at your code, it's actually easy to do. Make those class variables(parameters) global, make class functions(associated functions) as normal functions. Then call those from the switch statement in main_menu()

Why.. just why.. why do you want to uglify the code?

The teacher told us too

I was learning how to code a socket program in C. And i did it but i have a problem in my client code that i can't fide it and it's totally true . I am really confused. Can someone help me?

Ok Got it👍Thank You so much👍
