Why Is Hello World the First Program in a Programming Language?

"it is simple enough so that people who have no experience with computer programming can easily understand it. While small test programs existed since the development of programmable computers, the tradition of using the phrase "Hello, world!" as a test message was influenced by an example program in the seminal book The C Programming Language. The example program from that book prints "hello, world" (without capital letters or exclamation mark), and was inherited from a 1974 Bell Laboratories internal memorandum by Brian Kernighan, Programming in C: A Tutorial, which contains the first known version.

Why do people pretend that they don't know you or don't see you instead of just saying "hello" and moving on?

Several reasons:They dont like you, even if you never did anything to them. Some people wont like you no matter what. Its THEIR loss.They are preoccupied in thought and didnt notice you, even if it appears that they saw you.

They dont feel like talking to anyone because they are suffering emotionally. They may be depressed.Try not to let it bother you. If it keeps happening with the same person, then you know they dont like you. Better to expend your energy on those who do like you.

What is the output for in main char *ptr"hello"; ptr 0 'm'; printf ("%s", *s);?

The output in most big computer environments will be a segmentation fault or access violation, as youre trying to write to the text segment.In embedded environments, this *may* be writable, in which case Weird Stuff can happen, iechar *foohello;char *barhello;foo0m;printf(%sn, bar);printf("%sn", "hello");The output above may well be mello - twice - as the initializer string hello may be used for all initializations by the linker to save space.Kids, do the world a favor and dont try this at home :)

Hello. I am a 13 year old and I still have plushies that I like. Is this accepted?

Of course its ok! Im 18 and still have dozens of toys and plushies ive had since I was a child. I have a lot of trouble sleeping at night unless Im holding/hugging one. I have a few Ive gotten from my boyfriend and I will hug and alternate them every couple nights. Its perfectly normal, and kinda gives you that sense of comfort. Some of my childhood toys/dolls/ plushies I couldnt bare to give up. Again Im 18 and some might say its a little odd but I understand the reasoning behind it, there is nothing wrong with it!.

Why do Dutch hardly say hello?

This is a town versus country question.We live in the country and if we go for a walk we say hello and maybe engage in a short conversation with everyone we encounter.In the cities you would not do that.It is exactly the same in the UK except there is also a greater tendency to this kind of openness according to how far you are from the south east.We lived for 3 years in the USA - initially near New York and later for a short time in Boulder Colorado. We encountered exactly the same behaviours there. New Jersey was relatively unfriendly, Boulder quite the opposite

What do you think of answers on Quora which start with "Hello"?

Hello answers are perfectly OK where the word hello is part of an answer to the question.As a greeting, it's a bit unnecessary; a bit like saying thanks for the A2A Adam Ooi Wei Min () .It detracts a little from the readability of the answer, but that isn't a major concern as long as the question is answered, the answer is polite and respectful, and it isn't simply an excuse for spam.

Why do people purchase these dinner kits like Hello Fresh or Home Chef?

I have friends who do this. They like variety. They like to cook up a meal that they would never have thought of on their own, learn new techniques, learn how to use unusual spices. They like having all of the ingredients included. I had such a meal with them and it was wonderful. The fig jam was delicious. It was a great meal. I believe they got Blue Apron though. It isnt because they are too lazy to grocery shop, because they still have to do that anyway. Its because the meals they get by mail are really good and interesting

What is the output: for (1;2;3) printf ("Hello world")?

The Syntax of for loop in C programming language:for (initialization; condition; increment/decrement)

statement(s);First initialization is executed. Next, the condition is evaluated. If it is TRUE, the body of the loop is executed. If it is FALSE, the body of the loop does not execute and the flow of control jumps to the next statement just after the for loop. After that increment/decrement will be done of variable.Over here, In given example,initialization: 1condition: 2increment/decrement: 3Here condition is 2 therefore, every time condition will be TRUE so loop will be executed infinite times. Hello world will be printed on output screen infinite times.

Why did this C code compile with line: z"Hello"; although it includes using assignment operator with array?

char arr "hello" ; allocates a statically sized array of 6 elements, initialized to hello0i. You're not allowed to reassign static array base pointers. char z as a function parameter is really identical to char *z, a pointer to a character or the head of a character array of unknown length. I can imagine some compilers allowing you to reset the value of that pointer, since it's an input parameter and the change only affects usage inside the function. I can imagine other compilers treating the input parameter as a fixed pointer to the start of an array, and not allowing the assignment

Is it OK to not have any kind of relationship with women (even friendship) or even communication (hi and hello) outside of work because I find them to be manipulative and dishonest?

Well, legally, thats your right to stay away from all females if you so choose. But its not true that women are by default manipulative and dishonest. Perhaps you need to change your tastes in women to befriend, or move to a different town. Dont let your bad experiences with women in the past alter the reality and the fact that some women are manipulative liars, and some are honest, respectful people. Do what you want, but understand the truth of the situation so you do not someday infringe on a womans well-being because of a jaded view

How long does it take to learn the Hello World program?

About the time it takes you to read, print (Hello World). Depending on the language, the time this takes may include some other side-quests like installing an interpreter, compiler, IDE, etc. This is typically where the actual value comes of the exercise comes in. Writing a program that outputs Hello World forces you, to at least, understand how to run a program in that language.As a side-note, I usually opted for FizzBuzz rather than Hello World to introduce languages because it introduces various elements like loops, conditionals, some math, and possibly printing variables rather than just printing Hello World.

Why do Australians say "G'day"?

I wonder how common it is today actually. I had to go to Centrelink a couple of weeks ago, and was quite taken aback when the lady at the counter said, "G'day" to me. It was the first time I had heard it from anyone in about 50 years. Even then I don't seem to remember its being all that common.

I do have a vague recollection of hearing Paul Hogan and Steve Irwin saying it, but as "professional Australians" who played up to every Australian stereotype that ever existed, they don't really count

How do I say "hello" in Japanese?

If you're referring to , you can break it down like this: - KON

- NI

- CHI - WAThis first two syllables, are almost squashed together, but instead of saying (konichiwa), you need that extra N sound, to make it (koNni), you can practice saying this by just hanging on the N sound after KO. Slowly, it might sound like this: konnnnnichiwa.And of course the ending shouldn't be too hard: chiwa

* As a side note, should you have reason to question it, the hiragana for the WA sound in konnichiwa, uses the hiragana instead of (though this isn't required knowledge for just saying the word).

What if a male teacher tells me to say hello to my mom?

I'm sorry, it means he's saying Hello, I just dont understand why people think/assume there is a hidden meaning hidden/gesture/agenda behind everything! I honestly think sometimes people are looking for a 'sign' that just isnt ing There! I'm getting more and more annoyed with these type of questions.That question tells me "oh, say hi to your mum for me", am I missing something?I don't know wether this current world is turning PC crazy or into a pack of Prima donnas, who think every human interaction needs to be dissected to find a hidden meaning!Seriously people, get a ing grip of Yourselves!

I want to write a code that prints hello world as the computer boots up, how can I achieve this?

I think it really depends on what operating system you use:FOR WINDOWS:Simply not possible unless you are on the kernel development team or have access permissions to access the kernel and BIOS.FOR LINUX:You need to know the C programming language and need to edit the boot loader filesfor e.g. grub2 for Kali LinuxFOR MAC:You need to follow the above as same as Linux but edit it for BSD Linux since the commands might be different. All in all it is possibleSome other OS:I have no idea.Hope this helps :)

Where does the British phrase "hello, governor" come from?

Less to do with where it came from, I might add I don't give a rip where it came from, today I've experienced this more from less educated (or culturally exposed for that matter) people who hear someone (like my wife) with ANY English, Scottish, Welsh, or Irish accent and ask them to say this phrase like some circus trick on demand. I find it wholly insulting and inappropriate, there is nothing funny or light hearted about it the same way no one takes lightly the use of the n word. It's degrading and immediately causes someone to lose 200 IQ points in my (and my Wife's) perspectives.

How come a shy female coworker acts awkward around me but still says hello to me all the time?

Shes shy, you said it yourself. She probably says hi to a lot of people because saying hello actually draws less unwanted attention than staying silent.If shes shy and acting uncomfortable around you, shes not happy to be in your presence. She doesnt hate you, but you scare her or make her feel icky. You might want to tone it down some and keep your distance, youll both be better off. Dont ostracize her, just dont come on so strong. Talk gently, maintain personal space and just stay professional.

What should I do when a nearby stranger's child comes over to me to say hello?

If you dont want to talk to them just smile politely. Pretend you dont hear any questions they might be asking. If theyre very persistent ask Wheres your mommy? loud enough for the parents to hear. Most of the time the parents dont mean for their child be a nuisance to somebody else.If you dont mind having a conversation with them, then talk to them. About anything, age appropriate of course. Toddlers are not good conversationalists, but they arent looking for good conversation. Theyre just curious or bored"
