What Is Signed Char and Unsigned Char Exactly?

Nothing much, really. Check out this piece of code:int main() char ch; unsigned char uch; ch231; uch(char)ch; std::cout

when you reach the upper limit of the int value, and perform the increment operation, you end up with the lowest possible int value. With unsigned int, it simply restarts at 0.This is interesting observation in how C handles characters- not as ascii/utf/any-other-format values but as integers.

EDIT: Basically, there is no difference. Both behave in the same fashion and in algebraic arithmetic should give the same result. In comparisons, however, there may be some difficulties as the integral values are different beyond 127.

Is it worth doing cybersecurity degree?

It used to be the case in the 80s and 90s that most colleges if not all did not have a cybersecurity program. Starting in the 2000s, colleges started rolling out programs, and today, they're becoming more and more common.

Some of my peers I'd interned with at a cybersecurity consulting firm had cybersecurity degrees. They were extremely niche folks who knew they wanted to delve in the cyber field from the beginning. So I think, yes, a degree in cybersecurity or anything dealing with cybersecurity is useful enough, provided that you want to go into cyber.

I personally think computer science is a better alternative since it's broad enough to cover other facets of tech, but not niche enough to pigeonhole you to cybersecurity. Even though cybersecurity is demanding today in the job market, it's still a fairly niche area. Software engineering is still much, much larger

Is it true that Danish people say Norwegian people actually speak Danish but with a Norwegian accent?

Maybe thats stretching it too far, but still very close. A Norwegian can easily understand 90 % of written Danish, and vice versa, but the Danes pronounce the words very differently from Norwegian, some dialects are almost totally impossible to understand for Norwegians because of the pronunciation.But the odd thing is that Swedes usually dont understand Danish very well and vice versa.

I once heard a Swede and a Dane speak English together! I asked them in Norwegian why the heck they were doing that, and both understood me, and said that it was extremely hard to understand the other. Swedish can, of course, be difficult to understand for other Nordic speaking people because they have a very large number of words that have no equivalent in the other languages.

So if you dont know that word or can understand it from the context, you are lost.

What is the simplest C program without printf and scanf?

If the question is whether you can write a complex C program without printf and scanf, the vast majority of the worldu2019s C code would qualify, as these are rarely used in u201creal-worldu201d code.

Letu2019s consider PostgreSQL. I just did a$ find . -name '*.

ch' -exec grep printf /dev/null ;after downloading the source tree. This command searches all C source files and . h header files for the string u201cprintfu201d, and couldnu2019t find any.

There were fprintfu2019s in some places (mostly dealing with writing logs), but no u201crawu201d printfs.As for scanf, a similar search produces nothing as well. That said, PostgreSQL obviously does plenty of I/O.

It interacts with client applications using TCP/IP, it obviously reads and writes disk pages, and does chores like writing to logs and such things. But - like most large-scale production C code - it uses other I/O calls to do these.

Can I learn A.

I. or machine learning without programming?

Im going to disagree with some other posters on this one.

I dont believe you can attain a job as a machine learning engineer without solid Python and SQL skills.Most of what you are going to be doing is wrangling data. How in the world can you do that without solid programming skills?

Ive seen several data scientist, the PhD types, that were basically useless because they couldnt program.As the knowledge of model analysis continues to grow for Python programmers in terms of model selection and result interpretation I believe data scientists without programming skills will be at risk.If you cant massage data and build models then Im not sure how you can ever secure a real world job.

How do I start a conversation with a girl after saying "hi"? What should be the next question to ask or how do I not bore a girl in the conversation?

You go upto her , look at her with a genuine smile and say Hi. Now , her response depends on two things.First , if she was also into you secretly and she was just waiting for you to say hi .

Congrats , you've hit the jackpot . You just cannot bore her . She would laugh even at silliest joke you make.

Second , if you're not lucky enough and she wasn't into you then you can try your odds out .Here is the first 4 ques guide . If this didnt work then it quite difficult my friend .

HiI have been noticing you for a few days , you are really cute .If affirmative response like , thank you with a blush then just ask her can we hangout sometime ? If not affirmative then don't push it .

Leave it there to try sometime later.If positive , ask for her number.Now when you have her number , probably she would say yes to you if she finds you interesting enough.

So use your words wisely .

What C compiler supports all of the C11?

Standard C includes both core language and standard library, but C compilers and C standard libraries are, for the most part, separate products.

GCC and Clang both claim full C11 support (it is also the default for both, no need for -stdwhatever) and are working on C17 support (-stdc17 for both), but they both miss parts of C99 (fenv_access and the imaginary numbers) which other compilers implemented. See C11Status - GCC Wiki (canu2019t find a link for clang quickly)However, when using those compilers, you are likely to be using the GNU C standard library, which is still missing a large chunk of C11 (the multithreading library), which other standard libraries, such as musl, implemented. Intel C compiler also has C11 support: C11 Support in Intel C Compiler (the link says uchar.

h is missing, but itu2019s part of the library)Oracle, IBM, and HP C compilers, which (unlike gcc) implemented all of C99, I think still incomplete C11, but I havenu2019t checked for a few years

What is output of this given program and explain int main() char *p 1 "hello"; printf ("%s", (p) 0); return 0;?

As mentioned by Michal, the output will be u201chellou201d. Here is why:"hello" denotes an array of strings and char *p 1 is declaring an array to hold 1 character pointer.

The assignment operator will make the first character pointer point to "hello". Let's say if you had something like thischar *q 2 "namaste", "world"; Then q will be an array of two char pointers, first one pointing to u201cnamasteu201d and the next to u201cworldu201d.(p) means you are accessing the base element of the array p, and 0 means the 0th element from base, which means the first pointer in the array p.

Similarly (q)0 means first pointer in q and (q)1 means the second pointer, which respectively point to u201cnamasteu201d and u201cworldu201d respectively. #include int main(void) char *p 1 "hello"; char *q 2 "namaste", "world"; printf ("%sn", (p) 0); printf ("%s, %s n", (q) 0, (q) 1); return 0;Output:hellonamaste, world

What should I do if I am a racist?

Nothing.They are your opinions and preferences you hold dear, and no one can stop you being racist because your opinion isn't illegal and you would normally keep it to yourself.However, your passage through life will become increasingly untenable if you reveal your proclivities, and you are dependant on external actors such as employers or carers.

Racism is largely caused by perceived negative stereotypes which may or may not be reflected in societal relationships experienced by the holder. I personally believe in stereotypes as they nearly always reflect how people appear and behave, contrary to those that bemoan them.I have encountered racism, but I am realistic enough to accept that that's the position they hold through personal experiences laid bare to them, and just brush it aside.

Racism has had an unfortunate passage of time through those profligate with the term, and without clear understanding of its meaning, rather applying to suit their own pathos of self interest and pity.

How was the 2005 Charlie and the Chocolate Factory different than Willy Wonka and the Chocolate Factory?

There are a number of differences.

I loved the remake for anumber of reasons the main one being the fact that its a lot more faithful to the book than the remake does.An example of this is the scene which includes the indian prince, Prince Pondicherry and his whole chocolate palace thing.The second major difference, is the inclusion of the squirrels which Veruca Salt tries to catch before being unceremoniously dumped down the rubbish chute.

Additonally, we see a lot more of Willy Wonkas background including his relationship with his father Dr. Wilbur Wonka (this was a great move in my opinion).Additionally, we also get Dahls original lyrics when the Oompa-Loopas sing their individual songs.

Charlie Buckets entire family is here as well including his father and their house looks exactly as it does in the book.These are just some of the main differences between the two movies

How do I compile and run C programs in the command line using notepad in Windows?

You can write C programs using notepad and compile them using cmd.

All you have to do is to download MinGW Compiler and install it. Then go to its bin directory and look for gcc. exe then copy the whole path and set this in the environment variables (I assumes you know how to set env.

variables). And then apply. You are done.

Now you can compile your C and also C programs using CMD and if you want to compile for C then in the same bin directory you will find something called g.exe its for C, Just set the path and use it. Now after setting path you can type gcc or g in the cmd to check all working of not.

If it all set correctly and if you will type gcc in cmd and press end then you will get No imput file something like that error, it means you are good to go
