What Is a.out and What Does ./a.out Do When Compiling a C Program?

a.out is the default name for the output of a gcc style compiler. If you fail to assign a name gcc will generate a file a.

out that is your executable. In general a.out and .

/a.out are the same thing. You can invoke the execution of the file by typing .

/a. out. The .

/ just tells the shell to look in the current directory. It is used in the, rather common, event that the current directory is not part of the value assigned to the PATH environment variable

Is it possible to print without the main method in Java?

If you are using JDK version 1.

6 or previous then yes you can with the help of static block. Static block is a block which gets loaded into the main memory when the class loader loads the class and is executed before the main method of main class. But after JDK version 1.

7 it was made mandatory to have a main method in your program otherwise JVM wont execute the Java program.Hence you can do it if you really want but you have to use version 1.6 or previous otherwise in the latest and upcoming versions you simply cant.

Hope that helpsHappy CODING!

I want to ask my professor out after I graduate. Should I do it?

Sure. Let a time gap go there, but I see no problem with it. He's not your professor anymore , but keep in mind that he's probably gotten hit on by other students, and dating students is a huge no no, and is considered unethical.

I wouldn't worry too much about the 20 year age gap, but there is going to be dynamic going on in there because he was once your professor. If he's married, then, of course it's a big no. You might be interested just because you kind of put him on a pedestal .

All that said, I would say ask him out for coffee and hope it works out.

Is it racist to tell somebody to u201cgo back to their own country"?

Id say ish are they assuming your from another country or are they knowing it because it could be mean and nationalist. Or they could be just trying to hurt your feeling I dont have a car but if I did and a fat guy rear ended me and I got out and yelled at him watch the road you fat bastard. That would be mean and uncalled for it could have even been my fault it happened but it could hardly be assumed that I objected to him being fat.

Why do people get offended when you address a president by their full name, like Barack Hussein Obama or Donald John Trump?

Oh,me me teacher, me, I know this one!Virtually nobody publicly addresses trump as donald john.

However, Obama is frequently addressed as Barack Hussein, with an enfasis on Hussein, by the far right as a means to feed their bogus claim that he's a Muslim born in Kenya.So look to your left, look to your right. If any of you addresses Obama as Barack Hussein Obama, you are probably a far right racist conspiracy theorist that spends half a day listening to fox news and the other half listening to alex jones.

As a nurse, how do you deal with rude patients?

We don't.

Nurses will assess a person's affect, but never judge attitude.People react very differently when in crisis than they most likely actually are. Assuming rudeness or any other negative behavior as a natural nature of the patient would be extraordinarily unprofessional.

That doesn't mean we are going to take a lot of it either. Most nurses will work hard with a difficult patient in order to provide the best and most effective care.I have in my career found it necessary to confront an abusive patient.

It's not pleasant or easy, but usually effective

What is best website to learn cybersecurity free?

There are a lot of good ones. Try Cybrary (www.

cybrary.it) for free cybersecurity courses. You can also go to Udemy (www.

udemy.com/cyber-security). Finally the U.

S. Department of Homeland Security has several agencies offering free cybersecurity courses including US-CERT. My favorite is an entire program of training provided by Texas A&M Engineering Extension (TEEX) Service with three distinct tracks aimed at the business professional, the IT professional or for the non-technical practitioner.

Are Kosovo Albanians the same as the ones from Albania?

It is the same nation living in the same ancient lands for the last 3,200 years, since Dardanians were mentioned in the battle of Kadesh, where they sided with the Hittites against Ramses II.

Conference of London in 1913, accepting the requests of Russian, France and Britain, gave ethnic Albanian lands to their vassals and projects in balkans, such as modern Greece, Servia and small Montenegro.Unfortunately for Albanians, their allies lost both WW1 and WW2, a terrorist and fake state without any history was created in Balkans called Yugoslavia and the rest is well known.

Do native Jamaicans speak non-English languages?

Since we are one of the 14 countries recognised as Native English countries, it is important to note that the language primarily spoken in Jamaica is English. We do speak Patois, which was a remnant of slavery and is a mixture of several African dialects and English, however, we are also taught Spanish and/or French in High School, as a result some of us have basic proficiency in either Spanish or French, especially those within the hotel industry, since achieving a second language at a secondary school level is necessary (for many not all hotels) in order to be employed in afront of the house position

How many characters can the c_string char str 128 contain?

if you treat it as a string it can contain up to 127 character , the 128th cell will contain the terminating null aka '0' , if you read a string from the input stream , the array will carry the characters and will be appended by a null automatically , if you enter a string of length less than 127 , 5 for example , I will take 5 for characters and one for null , so always make sure during reading strings to have extra cell for the null , if you're not using the array of characters as a string , hence you will ready every character separately and you'll not have a terminating null character

Who generally make better programmers: INTJs or INTPs?

INTP in my opinion - not skill, just their preferences.In my work I have noticed that INTJ computer scientists / engineers tend to move to a business analysis or project management position quite rapidly - they dont seem to like programming alone very much - this may be due to the INTJs need for control over their environment / to ensure efficiency and success.INTPs I know are perfectly happy to bash away at really complex interesting problems on their own for ever.

They mostly could not give a rats ass what everyone else is doing as long as it doesnt interfere with them

How do you say baby in Hawaiian?

There are two ways to go with baby.If you want a general word for baby that does not include older children, that would be pu0113pu0113, which is basically a transliteration of baby into Hawaiian.

The word keiki applies to all children, including babies. However, there are various adjectives typically applied to keiki but not usually to pu0113pu0113 that are rather specific, such as keiki huli i luna ke alo for a baby that is not yet crawling. On the other hand, hou02bbopu0113pu0113 is used to mean to act like a baby

What should I do if I am a racist?

Embrace your inner racist. If youre white, youre going to be labeled as racist, anyway, so you might as well get used to it.Remember, it is not illegal to be a racist.

There is, and can be, not law against it. Just dont DO racist stuff. And theres the nub.

Not only are we all racists but everything we DO is racist, too. Between micro-aggressions and intersectionality, you cant win, you cant break even, and you cant get out of the game

How can one prove the existence of gods? Why would anyone believe that person?

As professor Ed Feser shows, it is quite easy to prove the existence of God which is why mankind overwhelmingly does. God is kinda obvious. Your free will alone shows you cannot be just physical and so what made you cannot be either.

We live in a world shot through with beauty, love , truth, goodness and faith. Carbon doesnt do that. Stephen Barr, the physicist is good at dealing with questions from people who mistakenly think there can be a real contradiction between a revealed truth, sound reasoning and science.

There cannot be of course. We live in a religiously and philosophically very dumb time

How do I print a character multiple times in the assembly language?

There are bios/dos calls that can be made on a pc to print to the display or the printer.

The dos one is redirectable to files and such If you want to go straight to the hardware you can write to video memory but then you need to set the current video mode. Because you are running this in a DOS box we can assume the video mode of colour text 80*25. This snippet should print A 25 times starting at the current cursor position.

How would the Romans react if you went back in time and showed them a map of the world?

Theyd be surprised to see the Americas. There was some notion that East Asia could be reached by sailing west from Europe.

No idea of a big landmass out there.Intererested to see that Africa could be sailed round. Not much puzzled by the Far East because their maps showed it.

Surprised at the relative smallness of Europe. A little suprised that there was so much sea south of the equator. (Even in the 18th century, Europeans were looking for a Great South Land.

Not vastly surpised that their own Empire had in the long run fallen

What is it like to marry an Albanian man as a foreigner?

"He had these swarthy looks, and muscled build .

I knew he was trouble from the moment I set eyes on him"Albanian men are physically very attractive and handsome, something about the genes I suppose, apart from that most Albanian girls would hate for anyone to take a Albanian man away from their home, their women are very possessive.Interesting I have also heard that the average Albanian male is prone to lying and cheating. Stay Away from the Albanian male would be my advice.

"A man is a man is a man, till I met him."
