C in 100 Seconds

The C Programming Language is quite possibly the most influential language of all time. It powers OS kernels like Linux, Windows, and Mac and many other low-level systems. Its syntax has inspired many other languages, including Cpp, Csharp, Java, JavaScript, Go, Perl, and more.

My professor had a saying: "You will die but C will live."

Love how it ends with a seg fault, describes the C experience perfectly

Becoming a programmer these days is like coming in to a movie theater halfway through the movie. Computer Science history weighs heavy over everything. After decades of messing around with computers and programming I understand the approach of learning things in the order they were invented- everything builds on what came before. Everyone should learn C first if they want everything that follows to be many time easier- because you will have context and won't need to constantly ask: "Why TF did they do it that way?" you'll already know.

C is beautiful in its simple complexity. I started in C++ 18 years ago, but I've come to find warmth and love in the C language experience.

"Use 🤣🤣🤣🤣
And those "C" puns at the end 👏🏾

C is such a simple language that you could learn the syntax in a day, learn the important parts of the standard library in less than a week, and learn how to use pointers.... eventually.

Being a CS student, transitioning from classes where C is the only language to now building modern apps with Kotlin/Swift and other various API's and languages. I now really appreciate the simplicity of C.

C is challenging to master because to truly use it well, one must understand fundamentally understand how computers work. This means having some ideas about registers and ASM syntax, while not required, greatly enhances interpreting why certain design choices were made in C.

C allows interfacing to hardware in straight-forward ways (custom registers, memory mapped peripherals) which don't really make sense in higher level languages. So C excels at low and mid level tasks where performance and resource allocation are the most important criteria. But it is difficult to be time efficient if you have to mix complex dynamic data, such JSON or web content.

Everybody: use print-F to print the value
Jeff: *Use

2:14 "Segmentation fault" - classic

[oliverdixon]

"Platform-dependent" in the context of compilers doesn't really imply dependence on a particular operating system; it means the native code is generated for a specified processor architecture, such as ARM or x86.

Quick remark, gcc actually means GNU Compiler Collection and not GNU C Compiler, the name GNU C Compiler was dropped around 1999 (in April to be precise) because C was only one of gcc's frontend.

[pragyan]

Ah yes the classic functions, print-fff and scan-fff

[peppi]

I still think C is the most perfect programing language. It's easy to understand to begin programing but has unlimited possibilities on what to build with it and it really runs on anything

[GuimoTheGizo]

C was my second language I ever learned. I find it kind of funny that your explanation of C is mostly what happens in the machine for _every language_ but that most people take for granted since so many popular languages have an interpreter and/or sandboxed environment holding their hand.

[orco]

Actually, as opposed to C's neighbours, one can really learn all C's syntax in 100 seconds... 😂

12/10/2011: 10 years ago, Dennis Ritchie past away, leaving the world the legacy of the operational systems and the internet that we use today.
He is the true legend, not Steve Jobs.

I love that I can actually understand every bit of this video now! I watched this when I first started learning c++ about a year ago. I’ve now taken two computer science classes and a web authoring class for html, css, JavaScript. As well as a course in Microsoft power shell. Nice to see I’ve progressed. Lol

One of my all-time favourite things is Exercise 1-23 at the end of chapter 1 in “The C Programming Language” It says “Write a program to check a C program for rudimentary syntax errors like unbalanced parentheses brackets and braces.” This at the end of the first chapter!! We only learned the very basics, and now Kernighan/Ritchie expect us to do that! I think I actually went back and did this exercise after reading chapter 5. But it still remains with me 40 years later as something that just seemed so “Wow!” …

If we look at the algorithm, next would be C++ in 100 seconds, C# in 100 seconds, Assembly in 100 seconds and finally Binary in 100. Last time in the react native, flutter and kotlin series, I predicted correct
