The C programming language was originally developed for and implemented on the UNIX operating system by Dennis Ritchie. C, a quite simple language, is not tied to any particular hardware or system. This makes it easy for a user to write programs that will run without any changes on practically all machines.
In scientific computation we use floating point numbers a lot. This article is a guide to picking the right floating point representation for you. In most programming languages there are two built-in precisions to pick from: 32-bit (single-precision) and 64-bit (double-precision). In the C family of languages these are known as
double, and those are the names I will use in this article. There are other precisions:
quad etc. I won’t cover these here, but a lot of the discussion makes sense for
quad too. So to be clear: I will only talk about 32-bit and 64-bit IEEE 754 here. Continue reading
The author of the blog “banterly.net” was recently looking through his university days archive and came across this following problem that he created for himself trying to understand how C++ inheritance works. It was not obvious to him back then and he remember that even for TAs and some developers it was not very clear what was the deal, with some getting the answer right but not the why.He still find it intriguing today so I decided to share it, hoping that it may also be intriguing for others.
IT conferences and meetings on programming languages see a growing number of speakers talking about static code analysis. Although this field is quite specific, there is still a number of interesting discussions to be found here to help programmers understand the methods, ways of use, and specifics of static code analysis. In this article, we have collected a number of videos on static analysis whose easy style of presentation makes them useful and interesting to a wide audience of both skilled and novice programmers.
What is Static Analysis?
Author: Matt Might
Static analyzers allow programmers to bound and predict the behavior of software without running it. Once used exclusively for program optimization, they have rapidly risen in prominence for areas like software security and automatic parallelization. The author takes you on a tour of the landscape of static analysis through the lens of abstract interpretation.
The Stanford University presented a guide of the main formatting standards of C++. The skill of correct code formatting is a very useful one, as it makes the job of others much easier.
Says Mosh Hamedani, author of courses on C# at udemy
Mosh, I just got my first junior level C# job. What advice do you have for me? What are some critical stuff I need to learn?
So, whether you’re looking for your first junior C# job, or you just got one, this post will give you an overview of the kind of skills that you need to be familiar with as a junior C# developer. I’ve tried to put it in a “learning path” that would give you direction, whether you want to build web or desktop applications.

In 1971, the USSR delivered the first planetary rovers on skis to Mars, whose task was to puncture the surface with a rod (housing a dynamic penetrometer and a radiation densitometer) to see if Mars was solid or liquid dusty. The first probe crashed on November 27; the second soft-landed on December 2 but didn’t manage to get out of the “shell” of the lander, so that attempt didn’t count.
If you are a C programmer, you must be familiar with macros. They are powerful and can help you ease your work if used correctly. However, if you don’t define macros carefully, they may bite you and drive you crazy. In many C programs, you may see a special macro definition which may seem not so straightforward. Here is one example:
C is one of the most important and widely used of all programming languages. It is a powerful language that can be used not only to build general-purpose applications but also to write “low-level” programs that interact very closely with the computer hardware.
