I was at school writing for a wrapper for a certain C library, when my classmate in the same course as Computer Engineering, asked me what language is the code I'm writing. It went like: Him: What language is the code you are writing? Me: C Him: Oh, C++? Me: No, C Him: Oh, C#? Me: No, Just C. [In a bit louder voice] Him: Ohhhh. Are people really this poisoined by the word, "C/C++/C#"? Is C really this underrated? submitted by /u/harieamjari [visit reddit] [comments ..read more

I have a file, 'bytes.h'. In it, I have a function declared and implemented called 'get_bit_u32'. The file 'bytes.h' is included in another file, '__all__.h', which is then included in 'main.c'. I noticed I kept getting this error: c:(.text+0x28): undefined reference to `get_bit_u32' collect2.exe: error: ld returned 1 exit status But my #pragma message for the file 'bytes.h' always went off. Weirder, all the other things I've declared and implemented in 'bytes.h' get included successfully and I can use them no problem. It's only that one function that can't be found. But for whatever reason ..read more

Hey guys, I feel like I just crossed this line where I can start building my first projects. I wanted to implement the GUI for my project in C. Are there any useful guides, courses, videos, articles, etc. that could help me understand how to work with the GTK library (this is the most popular one as far as I know)? Maybe you have other recommendations regarding this matter. I look forward to your advice. submitted by /u/KMC_PO_PMC [visit reddit] [comments ..read more

I'm currently in the design phase of a TCP server that I'm trying to build for school. I'm hung up on whether or not I should be using a thread pool, poll(), or a combination of the two? What are the pros and cons of each, and what factors help determine what methodology to use? submitted by /u/house_of_klaus [visit reddit] [comments ..read more

I want to write a program in C language that controls the chipset part of the computer and controls the hardware such as cpu, ram and performs various operations. How can I do this or is it possible to do this? submitted by /u/taM608 [visit reddit] [comments ..read more

Why it's not a good practice to call free() a lot of times after allocating a pointer with malloc(), calloc(). I search about that but i don't get a good explanation yet for this issue. And what happen exactly when you free a pointer from the heap memory. And why we should set pointer to null after freeing it to free it again. submitted by /u/ChernoKarim [visit reddit] [comments ..read more

I have very limited understanding of programming in general and the differences between procedural and object-oriented programming, so please forgive my ignorance. While I know how to do basic stuff, I believe not knowing how to structure things (in this case, a game) is holding me back from progressing. I have made Snake in C using Raylib, where the game loop has to specifically update the snake and the food generator. I'm thinking of going one step further for the next project, and have something that is more scalable. I have previously made an application in C#, but not using proper GUI fr ..read more

I've got a function that takes in as a parameter a const int32_t *p that I'm using to initialize a structure to some default values. If I just make a direct copy struct_name->table = p; The compiler hits me with a "warning: assignment discards 'const' qualifier from pointer target type." So if I cast it to non-const first struct_name->table = (int32_t*)p; It gets rid of the warning, but then SonarCloud says "cast from 'const int *' to 'int *' drops const qualifier" Is there a way to soothe both at the same time? What's the best practice here? submitted by /u/dimonium_anonimo [visit red ..read more
