Reading on Wikipedia: "The terms high-level and low-level are inherently relative. Some decades ago, the C language, and similar languages, was most often considered "high-level", as it supported concepts such as expression evaluation, parameterised recursive functions, and data types and structures, while assembly language was consi...
What's the bare skeleton to get a triangle drawn on an OpenGL window in C on OSX? I've gone through the tutorials at Nehe and tried to get it working, but the CreateGLWindow seems hopelessly tied to win32. I want to stick to just opengl and glut, etc. I'll be eventually wrapping this in scheme, but I'd like to have a firmer understandin...

I might be stupid and you need to excuse me in that case...but I don't get this. I'm allocating a buffer of 16 chars and then (in a for loop) put in 23(!?) random characters and then printing that stuff out. What I don't get is how I can put 23 chars into a buffer that is malloc'ed as 16 chars...When I change the loop to 24 characters I...

I'm programming in C and using Source Insight. I have an enum type with a lot of constants (like 100). I have debug prints that print out variable values, but they (of course) print out as integers. What I'd like to do is click on the name of an enum constant, and see its numeric value displayed somewhere. (I've seen this done in a V...
How can I write to/generate a *.doc file programmatically using c or c++? Is there a (open source/cross platform) library to do this? If this is not possible, can write an *.odt file and then convert it to *.doc? Thanks in advance! EDIT: Anders Abel commented that *.rtf file type is an option, so any suggestions on this one are also acc...

I'm setting up a ZABBIX agent (written in C) on a couple of Ubuntu 64-bit servers. I usually compile everything in 32-bit unless I specifically need 64-bit (such as database servers.) The servers in question will be hosting virtual servers and have 8GB RAM, hence why I've kept them 64-bit. If the ZABBIX agent starts as root, it tries ...
Could you suggest a syntax for the C language to use it in a similar way than an object-oriented language? I know that they cannot be the same and that some keywords aren't present in C, but I'm wondering if there is a way to take advantage of certain aspects (like inheritance) even in a C program. ...

For example, if I get this as a response from the API, how do I extract out the value of "text" into a string (char*)? I guess I can work with the string at low ...

I know the steps to make this client program but i'm lost as to the exact things I n...
I'm working in C with openMP using gcc on a linux machine. In an openmp parallel for loop, I can declare a statically allocated array as private. Consider the code fragment: int a[10]; #pragma omp parallel for shared(none) firstprivate(a) for(i=0;i<4;i++){ And everything works as expected. But if instead I allocate a dynamically, i...
