C Programming Tutorial - 9 - Do While Loops

[thecuber1122113]

haha....i'm 15 in secondary school,i just watch this for fun and i understand what you said.i've just gotten a new interest.

[Alexandros5th]

do I need to place int main (void) in the beginning? why not simply put main(void) or main()? and what's the difference between these three?

[Radnyxerr]

@Alexandros5th int implies it to be a value, the parentheses tell it that it's a function. If we said just main(void) then the compiler wouldn't know what it's returning. (int main() works fine too).

How to make your computer sound like a vacuum cleaner:

do {

printf("%d\n", counter);

counter++;

} while (counter>0);

[tedkenneth14344]

thanks for this video, this is a big help to me for this coming departmental test of ours :))..

[shuwukong]

you explained it very effectively thanks a lot

[mYnameiSma0]

what's the function of the counter? I'm sorry I dont know ..:))

[bondservant4Him]

@mYnameiSma0 it just shows the condition of the loop

[mastermax7777]

wow! i found something cool! try this:

[code]

int=1;

while(int>0) {

printf("%d\n",int);

int++;

}

[/code]

enjoy...

[bondservant4Him]

@mastermax7777 int cant be a variable name

[LightningHexagon]

@bondservant4Him Correct! And even if that "int" is a legal variable, that while loop will execute infinite times!

[cookiesRgood26]

change the while part to say

}while(counter > -1)

[NozFwbit]

I tried running this without initially setting counter to 1, and it began at 2 (i.e. counted from 2 - 9). After a little investigation, it appeared that counter was set to 2 as a default. Anyone know why this is?

[cookiesRgood26]

@NozFwbit did you set it to 2 or did it just start that way? I think that if an integer isn't directly given a value the computer just makes one up from 1 to 10. I may be wrong but while making an infinate counting loop for fun, I didn't assign a value to my variable and it started from 5...

[DrLafranz]

hmm.. i mean.. i guess do loops is a way of making a time delay between running a set of commands... is their a more efficient way of delaying time? im not sure if do loops are used for this .. but thats what comes to mind

[DrLafranz]

lol after he typed in coutner.. i was like... nooo.. u have ruined programming for everyone!!!

[psniwillrocku99]

try this 1

printf("%d", counter);

counter++;

}while(counter < 1000000000);



[DrLafranz]

@psniwillrocku99 u trying to crash ur comp?

[psniwillrocku99]

@DrLafranz no because i hav an alienware m17x i think it will be fine

[devesh16737]

dude u r the only one, u r awesome.Thanxxx a lot God bless you:-)

[jRedTree85]

which loop will result in faster average performance: do while or while?

[MrKyte12]

what does conio.h means? whats that for?

[cplusplusish]

@MrKyte12 conio.h is a non standard, little supported header file which should generally be avoided.

[MrKyte12]

@cplusplusish but what does it do?

[nulledsession]

Save some typing: do{ printf("%d\n", counter++); }while(counter <10);

[PivotBeguiner]

you should teach C programing at an university.

[shortlthug88]

nice tutuorials dude they realy help a lot

[Jugdesi]

[Mexicouger]

You have that cough every single Video xD

[SquigFacer]

My favorites on youtube, are; Ray william johnson, Jimmyr and you!

[enesog]

How to Test on numbers in general????

so if I typ an character it should be wrong

and vice versa. on characters.

if I Typ an number it should be wrong.

[crazynoob11]

You skipped for loops! D=<

[aydinliq]

that was neat and informative. thanks!

[mopmop3434]

this is great dude! i hope u make alots of tutorials... nys whooping cough hehe...anyway thank you again

[sujeshanto]

great job friend

[CraigMcAllisterMusic]

9 Tutorials in, and still got the cough..... Gutted

[hotvampire1992]

@CraigMcAllisterMusic :-i think he did all d tutorials on same day.

[metallicarula]

why is the void inside the main parentesis?? for what is that?

[TurKdiRty]

do you do pic microcontrollersssss? and header files?

[0121ryanh117]

@TurKdiRty wanna learn about header files? Message me, ill try to help you/.

[deeshrn520]

would u tell me whatt software u using??

at this moment, i am using visual studio 08 but it still good as ur's during show the error

i reali like that

thx...

[natshamo]

TQ very much, your tut are awesome, but one Request, when you have your "whooping" cough, don't cough in the mic, as it looses my atttn span, Please cough away.

Thnks

[persianqu33n]

wtf!

if you wanna learn,you have to love his whooping coughs aswell!

[ManiacAfro]

I hope you are joking, other wise you have the attention span of an infant

[tedtdu]

your HP is opened in Japan. Anyway, more C tutorial please

[alshezfatm]

i really like this tutorial.. every easy to understand.

[lodikr]

dude thank your for C tutorials, they've been a great help!

[xxyuri]

it worked fine for me

thx

[bikarida]

any1 know why i keep getting 2293620 9 times down the screen when i compile and run the program? all other tuts have worked fine up until now :S

[TheMaksud]

great .....................

[biswa12341234]

hey ur tutorials are really simple to understand and geneterated a new interest in C programming,,,thnx a lottttttttttttttttttttttt.

[Titanium640]

Exactly. I been trying to learn in C, but couldn't find any tutorial to keep me informed of what is going on. Next, I tried learning in BASIC, but found it too hard. Strangely, now I find C programming much easier with these tutorials. Hopefully I can master it. Great tutorials!

[pliskinn0089]

the hardest part for me was to find a good compiler. this one is awesome because it begins right in the beginning downloading the compiler the configuration and stuff

[TheThissucks123]

its kind of fun too. And if you ever plan on working with video games, you need to know C or C++

[Moisesireyes]

@biswa12341234 faggot.

[crta50]

i hate loops :O they are hard for me, iam never getting them

[samljer]

Posted a C++ version of the tutorial

[kandelbiz]

Bucky Your tutorials are like of the pros.

[Smartformer]

Thanks!

[selvaaai]

good job

[TechApplePie]

Fine job. Not extemely high use of this though in the wild, as far as I can tell. But when its handy it really handy.

[bigfaggykitty]

while(1)printf("FAGGOT");

[gary0110]

nice
