[@javabeanz8549]

Been a lot of years ago, but I wrote a bit of 8086/8088 ASM. In my course on Digital Computer Electronics, we did a few projects, the final project being a stop watch on an 8086 trainer. Outside of the class, I coded most of an ASM program to read a clock chip on a Leading Edge computer, and set the time in MSDOS 3.2. Funny thing though, they made enough changes in 3.3 that it didn't work. So I gave my classmate a copy of the code my instructor and I wrote. I don't know if they ever got it working on 3.3.

[@vieilatome2257]

Huh.. you can write your OS in C? I mean the usable,not just boot with command line interface There's one of the Projects Mr.Dennis Ritchie himself head on development like Plan9,Inferno OS,Limbo (programming language) which are available in opensource Dennis Rotchie lead it as original intended way of creating C:portability,sharing with peers Until Java stole it with "write once,run anywhere" marketing catchphrase with chip industry growing & no cooperative plan to make ports for common purpose (thus leads to ever spewing "backward compatibility" curse that haunt the whole computer science industry) Some easy examples are Python,Java with their new versions simply outdating their own past versions (and they force it by stopped "support",No community or people be care like that) So back to the original convo,how could you (would you ever before actually?) Write OS without using Assembly & how 😳 Please share more info,you could check my channel too 😊 As sharing is what makes computer science one if the good communities leading the world 😅❤🌏🎉 Wish all be well 😃🌟✨🙌 25.07.2023 06:00/01 pm ist 4rea,25 like,1Ma

[@____________________________a]

this is for the average smart person who has basically 0 experience with the concept of programming, so some context of how programs work and some general programming theory would probably be necessary for comprehension

[@officialbfi01]

Assuming you really have been programming with C since it’s creation in the early ‘70s, you have decades of experience with the language so clearly you’re not the target audience for the video. For anyone who hasn’t seen C code (or any code) before, this is a concise and thorough explanation of the very basics that other KZbin videos would spend 10 minutes describing yet here is done in under a minute. I would like to say though that if you actually have been programming for 50 years that is pretty cool 👌

Now explain to the newbs that puts() is for strings but if they want to print a variable they have to use printf(). I've been asked about that a few times over the years.

[@informativt]

the f means format. they do different things.

[@seremptos]

So you mean that puts is useless, because printf can do exactly the same thing, but even more

[@mgord9518]

​@@seremptos It's not useless because it's faster and also automatically adds newlines. In situations where you're not using any variables, it makes little sense to use printf. Although, every modern compiler I can think of will automatically convert simple printf statements into puts.

[@seremptos]

@@mgord9518 oh yeah makes sense but like in school we only learn about the printf

[@informativt]

@@mgord9518 It's not useless, as it is predictable. Eg if you feed it something that looks like a format string it will behave as expected.

Why is there a Void there? "Void" in english means an empty space. It's means nothing. If you say void then anything after it means nothing.

[@DavesGarage]

And that pointer points to nothing yet, just the address. It won't be a "thing" until cast to another type.

[@givowo]

i thought it meant something that you put something into but get nothing out. since you would replace void with the return type (meaning something will be returned) it means that void wont return anything, so if a void has parameters you will give it data but not get any out (directly, since ofc you do stuff in a function)

@@NotEight that’s not a contrary statement to mine. Most programming languages are simple and have an easy to follow syntax. Programming is more about the problem you are trying to solve, not so much the language you write it in. Like you could write a compiler in many languages that are simple to read, but it is a complex problem. Or, a middle schooler can read, but could they comprehend an essay about theoretical physics? They can read the words probably, but the ideas wouldn’t sink in. It’s great that you’re learning more and more, keep going and keep building

The letter “C” holds a distinctive place in the English alphabet, often recognized for its versatility and varied pronunciation. Its phonetic range allows it to represent different sounds, including the hard “k” sound as in “cat” or the soft “s” sound as in “cent.” This duality contributes to its widespread use in constructing words across various contexts, making it an essential component of language. In linguistics, “C” also plays a crucial role in understanding phonology and phonetics. It is classified as a consonant, which means it typically requires some obstruction of airflow to produce its sound. However, its flexibility extends beyond this traditional classification, as evidenced by its ability to mimic both consonantal and vowel-like qualities depending on its placement within a word. Beyond its phonetic significance, “C” holds cultural and historical significance. It has been part of numerous ancient scripts, evolving over time to its current form in the Latin alphabet. Throughout history, the letter “C” has been associated with various symbols and concepts, often representing notions like creation, continuity, or change in different cultures and mythologies. Moreover, “C” serves as a cornerstone in modern communication, appearing prominently in various fields such as literature, science, and technology. From composing compelling narratives to formulating complex mathematical equations, its presence is ubiquitous. Whether it’s in crafting elegant prose, deciphering scientific formulas, or navigating digital interfaces, the letter “C” remains an indispensable element of human expression and understanding.
