Lecture 5: Clarity (C programming #2) - Richard Buckland UNSW

[kay00k]

Skip to 8:00 minutes. Thats when the class starts

[jhamien920]

Learning from this classroom is fun. Very light discussion.

[Warndog9]

Idk I like his lecture style and how he keeps the mood light but I notice that 30mins into the lecture all you've really established is what was taught in the last lecture

[DOVARIRAMU]

waste of time.

[Sam9227]

i thought charlie sheen was lecturing for a second (at a profile glance anyhow)

[rflejeune]

Its pronounced "vee eye".

[syslogblogger]

Not a single professor at our uni would help a student in such a way richard did at the end of the video. kudos to him for beeing so cooperative.

[imasexyborat]

Lol, love how this video has the 2 entire one on one conversations at the end >.<

[sonay1986]

he is a very nice guy, but not a really good teacher, he spends a lot of precious time with jokes and irrelevant stuff. I have watched 4 lectures (more than 2.5 hours) and the content was about an hour or maybe a little more...

[gpietsch]

The printf function actually returns the number of characters printed, but this is not very useful.

[slier81]

thats y i rarely read something in wikipedia

it sux

[darkdudironaji]

@slier81 wikipedia is much more credible than people say. Try changing a wikipedia page with out any reason behind it. itll change bac

[bR4GE]

the sound needs to be syncronized..

[Daevas88]

The audio and video is 5 freaking minutes of at the end oO

Great lectures though.

[eanwahm]

Splendid learning resource. Can somebody from UNSW Learning please sync the audio and video and re-upload it online.

[0121ryanh117]

@eanwahm Its youtube that takes the videos out of sync.

[sreustle]

Great section of lectures, but this is a really messed up file, between the audio offset and ending :P

[gigibastar]

he is funny :))

The name a.out exists for historical reasons, it is short for assembler output.

[hachnslay]

i wish i were there too! i could have passed that basics of scientific programming! ...

[TechApplePie]

"We're very horribly humpedly sorry. Vidoe is no longer available! " KRICKEEYYYY!!!!!

[TechApplePie]

Clicking on 'lower quality' makes the video magically avalable. prob is now i have to squint garsh dawnit!!!

[plaguez1337]

Sound is way off.

[mcshadypies]

Wow, I completely love this guys lecture style. Very cool :-).

[oringent]

@mcshadypies I dont know what you find so great about is lecture style. its a pretty bad presantation of the actual stuff. not a lot substance, lot of comedy. But you are not at uni for comedy mate. The stuff he taught in the first 5 lectures could have been taught in 1hour.

[pagola]

@oringent u clearly dnt understand...he knows that..he just wants to make a very boring subject interesting to first year students thats why he choses this style..not everyone is a geek like you

[oringent]

@pagola If people think this subject is boring they shouldn't take the course and he should know this. He is making it look all easy but once these guys try work on a real project they will fail. He needs to cut the bullshit and be straight with these ppl.

[PerverseBannana]

@oringent He doesn't "Make" it look easy. The beginning parts are very easy and thats why it looks this way. He's doing a great job teaching it, and I don't see any reason to complain. The fact that he's taking it slow is only helpful to the students. Also, it's a lot easier to learn something when the presentation isn't boring.

[oringent]

@PerverseBannana I think he is extremely boring. Instead of talking about real programming he is cracking jokes. What makes programming interesting is reasoning and logic but not jokes. If this was a class of computer science students they'd feel ripped off, trust me.

[flexo87Milaye]

Very nice lecture! A funny way to learn C programming!

Anyway there is still some warning, try to compile with the "-pedantic" option and you will see that gcc doesn't like so much C++/Java comments! ;)

[lYrICalsSH]

nice lecture and all but its kind of annoying how the sound is off by a wide margin

[corypollard]

1/ download

2/ open in mplayer

3/ adjust audio/video sync (+ and - keys)

4/ learn

This guy is awesome. I'd love to be there.

[corypollard]

4100 milliseconds to be exact.

[eXX0]

Thanks for that :D

[sspoke]

Also as a number repeater without using if statments while(true) { cycle = cycle % 5 cycle++; printf("number %d", cycle); } would print 0,1,2,3,4,5,0,1,2,3,4,5 forever. Thats I consider the best way explaining that operation. instead the crapy way would of been if(cycle > 5) cycle = 0; cycle++;

[serendib7]

This will actually print 0-4. %n can never return n, since 0modn == nmodn

[sspoke]

I quit programming a while ago but I still think it would of gave 0-5.. oh reminder of 0 is 0? well thats good....... exactly what i ment i don't see the flaw here you should try to run it..

i dont even think u need a cycle++; line just do

cycle = cycle++ % 5;

[sspoke]

I think my explanation of % (Modules) would of been better and easier to sink in brain. It's used mostly for ticks of loop or repeating old numbers in loop.

example:

int cycle = 0;

while(true) { if(cycle % 500 == 0) { printf("cycle = %d", cycle); }

}

answer should be

500,1000,1500 when it reaches the max int value and goes negivate it will still work

-500,-1000 and so on.

[DavidCoppens]

Kind regards from Holland, nice lectures.

[pazaakgirl]

I think Rupert and Thurston control the camera... not entirely sure though because you can't see them from the box in Rex Vowels.

[SushiBoiUTS]

is there someone controlling the cammera?.. or is it tracking it

ps i'm not from uts.. i'm in 2nd year
