C was the first language I mastered, and it made it very easy to jump to Java, C++, C# and even x86. Even with no object orientation, it helps build a strong foundation.

[@oODomeeOo]

I learned C very early with microcontrollers. Additionally learned C++ which was an easy transition. Though learning to program object oriented when you were programming procedural for years was hard. But going to high level languages like C# or Java is a pain. I have real trust issues to shift my freedom of memory access towards the interpreter. Also to have just a library for everything and just use them is hard, when I don't know whats happening in the background. I just feel disconnected from the computer. So I try to stay away from those and keep programming near the hardware. :)

oh i also know in c++ how the assembly looks like, but to be honest, you want to stay away from there! for example: 2 classes with inheritance will basically create tables of function pointers and based on which constructor function is called this "virtual method table" or VMT will be filled with different jumps to different places of or code... and i'm not even speaking about the memory layout....

[@TheEVEInspiration]

​@@NiekNooijens You can know it for even higher level languages than C++, in the end its having the understanding of how things really work that is important, no matter where you code in. Its good if you think of the costs when opting to use virtual functions and then reason about it if its really needed or acceptable to pay the cost. The problem with C++ and OO languages however is that as the abstractions accumulate, poor choices get cemented in and become the foundation for a new round of code. Choices once made, are hard to revert as everything is knotted together. Sure the code is abstracted, but that hardly matters as everything is still tied on the interface and architectural level. Its a code oriented approach and that is why OO is a scam and a dead-end approach to software development. Programming is about data, not code, so unless job security is the primary goal, stay away from OO or use it in only limited fashion as a tool to organize large domain blocks.

@@ricknash3055 Yes. C was created in the early seventies; the book was the "official" bible on how to write programs in C. I bought it immediately. I was lucky enough to be given a beta of a C compiler written by a person (Mike G.) who worked for a computer manufacturer located in Texas (this was a personal work by Mike, it was never released). I started playing around with it and immediately liked this language. I already had experience with more than half a dozen other languages but nothing was even close to what I imagined I could do with C. In the end, it became my main language to write hundreds and hundreds of programs, from applications to utilities. I even wrote complete data communications programs like emulators and comms servers in C. I could not have done this without C and the various compilers created by some very good companies and persons.

[@goedeck1]

Sir, I read K and R but had the question how to provoke EOF in say putchar getchar programs? You can't type eof because getchar will see it as ' e'. I thought of prompting the user to type a selected char that then you define as -1, then ask the user whether they want to end the string or use the char.

[@ronfarmery]

@@goedeck1 Run a simple test loop... #include int main (void) { int c; do { c = getchar(); } while (c != EOF); printf (" End "); } The compile and run it. Type some characters, then do Ctrl+D. See the result. Run again, type some characters, then do Ctrl+Z. So, no need to checking for characters but note the difference between Ctrl+D (program continues to run and prints the end message) and Ctrl+Z.

He's so right. Nowadays people tend to just completely ignore of how optimized and efficient the code is, despite the fact that the speed increase of modern computers is decreasing with each generation. People write unoptimized code and think it's okay. In 90-s we thought with the computers getting faster and faster we will get applications that will do stuff for us so much faster and instead we get a bunch of unoptimized code that barely matches the speed of applications of 90-s...

[@billatkin3956]

That's so true! Sometimes, when my computer is taking an age to complete an operation, I'm thinking 'Why the hell is it taking so long? What on earth is it doing to take so long?'

[@64BitLamp]

It's optimized because its borderline machine code. The more low level your code gets, then technically yes it is more optimized. I've been down the path of writing everything by hand with no libraries or dependencies (HTTP servers, database pools, auth API's) and I can tell you for a fact that you are creating nothing but problems later down the road. Enterprise doesn't always care about speed when it comes down to nanoseconds. It often cares if you can easily move your codebase to a new platform and if others can pick it up quickly. I'm not trying to dawg on C. I love C. I'm just saying it has its use cases (aka stuff really close to the hardware level). I don't need to access the A register from my API. Another thing to point out is C is processor specific, so it can be a nightmare trying to build separate environments. On the other hand I know that the JVM will run on almost anything without a fuss.

Never learned C, only ever learned BASIC before deciding that programming wasn't really my main interest. Still, I don't have much trouble reading C and getting a basic understanding of what the code is doing. It's almost unavoidable that you will have to look at some C code and build processes while dealing with Unix systems for 20+ years. I would have absolutely zero idea what a block of FORTRAN or COBOL code is doing, and no hope with assembly or machine code. The fact that someone proficient in C can do almost anything with it, and a layman can still look at a block of code and decipher a good deal of it - that's a great language. Maybe someday I'll get off my ass and learn it when I have nothing else to do.

[@kjetilhvalstrand1009]

The problem with C++ is hidden allocations, the things you don't see, it’s the tendency to write complicated code for simple tasks. on the other hand, C++ is good for complicated code. Its about finding the balance. A C++ string is abstraction of methods, data, memory management, a array of char, is just a array of bytes.

[@jjl772]

That's only really true if you use the STL though. You can choose to write C++ in the style that I call "C with classes", where you only use built-in language features like classes, namespaces, lambdas, templates, etc. and avoid using the STL wherever possible. I agree that you can accidentally write over-complicated code with C++, but I think a big part of writing good code is the mindset going into it. If you're writing a really simple application, you need to go in with the "C programmer's" mindset, meaning you utilize more basic language constructs instead of shoehorning classes, lambdas or templates into the program.

[@kjetilhvalstrand1009]

@@jjl772 I don’t think templates are bad, after all a template is way to make new classes by inserting stuff into it, I’m sure the code becomes bloated, (size of the code), I don’t think it impact speed. Names spaces, just a quick way to rename a bunch function variable, there nothing really wrong with it. Lambdas can be bad I have not looked into this, any function you create will always produce some overhead, but then again it becomes a question is your code readable, or is it not, if doing lot of copy & paste coding, you probably should be using a function or methods, or function pointer or whatever, it all depends. It’s not that lots of code is bad, or little code is good, its just that lots of the same, often result in some of code not being fixed or updated, and so it results in bugs. An example of more code being better is when you unroll loops, remember its not the number of lines on the screen that makes a difference, it’s what being executed that does..

[@jjl772]

@@kjetilhvalstrand1009 Of course, I'm not saying templates are bad at all. I personally use templates in many of my projects, as they're useful there. In more simplistic applications I avoid templates and lambdas, because I don't really need to use them to parse command line arguments, for example. As for performance, templates, classes and namespaces don't impact it at all really, unless you're using virtual methods inside of a class. My previous reply was really just addressing complexity from the programmer's point of view. All these high level language constructs can damage readability if overused or used improperly, and I've personally seen a lot of code that really overuses this type of stuff.

[@kjetilhvalstrand1009]

@@jjl772 I compared the string vs chars[], but there also things like initializers in classes, while C use bzero( &var, sizeof(struct hello) ), in initializer in classes you often start setting individual public and private data to 0, instead of using optimized routine to clear everything. So again, coding style produces worse code. You start think about what is inside the box, instead of think about the box. And some times you forget you are dealing with box lots stuff, because all looks like a simple type.

@@kjetilhvalstrand1009 std::string in C++ is known for being slower than C strings usually. The only good thing about it is that it stores the length, so you dont need to call strlen all the time.

[@anvarnasar7716]

It is not the fault of PHP. That is how the implementation of basic printf() and scanf() io functions is implemented in C. I didn't know this until I read some books about linux system programming in c. You have to call the kernel commands and do a ton of stuff like memory management to do io and every io devices are treated as a file in linux systems. In the case of C they implemented this as stdio on the standard c library which comes preinstalled with linux system. By default your c program is linked to the standard c library if you include header files like stdio.h. I think you can get one like that for PHP from composer or something.
