Hi👋 I want learn c programming. What is best book for c peroffetional?

I am trying to study or understand Linux kernel. I know it is not easy and even study word is not suitable here so say: get benefit of what is written there. I found a book written by a Chinese author for 0.12 but that is obviously outdated and does not have many features I want to get benefit of which such as network, TCP/IP, CDROM drivers, and so. It has also some bugs (clearly because it was not officially released yet); although they are selected, it does not seem good to read a code even its author regrets parts of it. I downloaded the current release of the kernel. It seems really big. I do not want to admit, at least not now at the very beginning, that I cannot aim for the whole current release. The most of my purposes of this task is for embedded systems. Can anyone give me some ideas and suggestions: where to start, what to focus on, what is the best way to do it, is there any book to speed this task, etc. One could suppose me have the basic knowledge needed for this.

I shall accept more ideas and advises.

A prime number is divisable only by 1 and itself The only prime number is 2 Which logic can be used?

you'd get the answer for that in seconds if you googled it, its a pretty straight forward question, that's why

Hey guys.. I'm a biginner in programming.. Just started with c

What ?

Why ?

how i can secure my tcp client with hanshake ? i use rsa and aes cbc 128, generate random iv, encrypt data with aes , , encrypt iv with rsa and send to client ,That's enough ?

What ?

The reason is there

I am trying to input a simple csv file. but I have a problem with the last words of each line, because they don't have ";" delimiter at the end

https://pastebin.com/Anxy9fgs any ideas of how to include the last values?

Hey there. I am creating a class that will wrap functions, and it is templated so I can wrap any functions. This class has a constructor that takes the function it will wrap. So, to wrap a function, I would do: auto wrapped = Wrapper<return_type(argtypes...)>(func); The problem is that it has unnecessary typing in the template, as the function signature is known at compile time, rigth? So the question is how can I avoid this ( by somehow getting the class template from its ctor's argument?), if it's possible

Language that you're using is less of an issue. The main issue is with algorithms. Read about https://en.wikipedia.org/wiki/Model_checking

How to solve determinant of matrix?

laplace algoritm

but is pretty hard, to code by yourself, maybe you can find a library

but is pretty hard, to code by yourself, maybe you can find a library

Do you have a little bit direction?

is the matrix of a fixed dimension ?

Not at all.

Not at all.

Besides, do you have a hint for divergence and convergence sequence? If so,how can l write in a big deal?

you can find on github, maybe

How to solve determinant of matrix?

I think you should try. First solve the problem for its simplest version then use paper to find how the larger one is similar and where it is difference. I highly recommend you to carry a linear algebra book through the solution; because usually, problems are easy but we need to know what we are supposed to do. Try to do it yourself without looking at any finished code.

Is that real? I don't understand. Even my compiler doesn't understand it. I think his compiler and he can understand it.

Finding the determinant of a matrix require you to know linear algebra, is not so hard after all but you have to understand the algoritm then try to implement it https://youtu.be/cAARX18-74g

What can I use in place of ExAllocatePool and ExFreePool in ERAM's code?

Oh

I didn't read that rule

I tried some other functions but they either didn't work or are missing a variable

It is unrelated to C++

It's possible, if you're brave enough ;)

Well that doesn't cover domain and all of that part of his question

Which is still C++ unrelated

Yeah, sure, my point were just to say it's still possible, even that there is much suitable technologies for web development exists.

Hii

Heyy silly question: A string that's initialized with a char array copies the array or keeps a pointer to it?

Hey anyone have any idea I can learn and practice c/cpp

Heyy silly question: A string that's initialized with a char array copies the array or keeps a pointer to it?

In C it is always pointer... there is no such thing as "string".

Depends... what do you wanna learn it for?

Yes this is where I’m lost. My interest are in building stuffs like arduino and also cyber security stuffs

You should learn both separately

You can do everything with C++, but it doesn't mean that you shouldn't use other languages for that purpose I personally specialize in C# for basically everything and know C++ only for embedded systems, primarily arduino

Fair, thank you But does it keep a pointer to the original character array I initialized it with, or does it copy its values to a different one and keeps a pointer to that?

Hey everyone,may i ask something that want i know,can C/C++ use to game engine script ?

Hey everyone,may i ask something that want i know,can C/C++ use to game engine script ?

I know not of any engine that uses C/C++ as a scripting language, but you should look around

But if you want to script then use Lua or other similar scripting languages There are a couple of great game engines that feature C# as a scripting language, too, but afaik they compile it into IL so technically it's that But then again, I don't know of any instance of JIT'ing C# directly

Okay thanks for your explain

Well as I know cpp can be used to create some programs for everyday use right ?

Of course, and it's very good at it

But more complex programs could get troublesome quick, and possibly unmaintainable without proper experience C++'s unmanaged memory makes it a hellscape for programmers just starting out

Of course, you'll eventually have to get through it, but it's for desktop apps languages like C# are better imo Managed Memory, almost guaranteed portability, lots of libraries and powerful technologies, etc. C++ is a great language, but I don't recommend it for everyday use

But basically everything you can do in anything, you can do in C++ In fact, pretty much everything has its roots in C++ For example, C#, Java, etc. are semi-compiled languages, they get compiled into an intermediate language, and then Just-In-Time compiled into the local machine's assembly code Without a runtime compiled for the specific machine, it's impossible to run them C++ compiles directly into assembly code, ready to roar in the local machine Which is why it's used in Arduino and other microcontrollers, it has the language features to talk directly to hardware and do anything you might need from itself

But at the same time, C++ is VERY big, far too many things to learn, and it can either be extremely slow or very quick, depending on your experience with it Also machine code is usually not portable to other platforms Which is also why most people shun it And let's not mention how easy it is to cause a memory leak and either throw a wench into your program, provoke a MEMORY_VIOLATION_ERROR, or worst case scenario cause a blue screen It's not imposible, but several levels of harder in C#

But don't let me scare you, everything programming-related takes time to learn, and C++ is very fun and very powerful ... I just don't like it for everyday use

Can anyone help me with my request?

Krishna loves Radha and wants to propose her in a different way. He wants to tell her the message, but he wanted the message to be a surprise. So, he plans to encrypt the message and send the encrypted message to Radha and he also gives the key to decrypt. He thinks that this might be a surprise to Radha. Help Radha to decrypt the message. Rules of encryption : 0<=key<=51 The original message only consists of a-z, A-Z, and space. Spaces are encrypted as '.' If key lies between 0 and 25, then the character is added with the key and modulo is taken and the case is maintained. For eg, if key is 3, then a is decrypted to d and e is decrypted to h. If key lies between 26 and 51, then the character is added with the key and modulo is taken and the case is inverted. For eg, if key is 29, then a is decrypted to D and E is decrypted to h. Input First line consists of t, the number of test cases. (1<=t<=20) For each test case, first line consists of key. 0<=key<=51 Second line consists of the encrypted message S. |S| <= 100000 Output For each test case, display the decrypted message in a separate line.

Pls tell the solution asap

Fair, thank you But does it keep a pointer to the original character array I initialized it with, or does it copy its values to a different one and keeps a pointer to that?

I have no actual idea but I think different compilers do it differently, I think the original C complier would not copy it because memory optimization, but new one might do it for array flexibility.

"string" in C is just a char*. Char* doesn't copy anything. It stores address.

#include <iostream> int main() { int sum = 0, val = 1; while (val <= 10) { sum += val; val++; } std::cout << "Sum of 1 to 10 inclusively is " << sum << std::endl; return 0; }
