The Best Teacher on Youtube :D

[MASTERHACKER1111]

9 = 5;

thumbs up!

[yusf22]

Thank you ^^

[Noldyie]

haha I have this in highscool, and I never go because I sit there for 6 hours a week, and this tutorial is much better/faster. after 4 weeks we are finnaly at this part of the 10th video, so I think it's not the best teacher xD

[abeil]

One of the best videos that i've seen on youtube................i dont like programming but after watching your videos ,i started to love C plus plus.Thank for your help.

[vladislavgenov]

For VolureDarkAngel:.....and you can talk if you did better than his lessons!:)

[cheatmaster1211]

im 13 so beet that lol i moved to c++ from .bat

[CheeseToastHax]

i dont understand why you use integers in programming.. i mean.. couldnt you just use cout << "text" instead of putting a and b and c ect..

[masteroforkut]

TY so much!

[visitnajr]

u filipino?

[dudemanhoar]

5:38 = gunshot lol?

[TehUnseenForce]

@DKeller4113 Wow Im 14 too! Wait... you're 16 now.

[graffitigalway]

@TehUnseenForce haha :D

[iWriteUinMyDeathNote]

@TehUnseenForce i'm still 14!

[ThuSkyline]

r = t * y = x

Dude, stop it or you're going to divide by zero and end the universe.

No but really, just so make sure my logic is right. r has the value of whatever t * y = x is, right?

[KvalnirFox]

This is somedeep shit:))

[cplusplus0x]

for live help

#cpphelp on irc.mibbit.net, webclient at mibbit.com ;)

[TheMuffin100]

"Use it for something we want to use."

I like this guy!

[Foaman]

Maybe I missed a vid or two on comments, but I'm really enjoying this so far. Thank you. Can't wait to keep moving forward. :>

[franklynvoorhies]

thank you for the great posts, been very helpful



[Rickyfre5h]

I have learnt more about c++ in the last couple of hours than i did all last weekend reading tutorials from the internet. Very much appreciated, Thank you

[thehumor]

how do you divide intagers

like with kill deah ratio?

is that k / d?

or what is divide sign

[thehumor]

im 15 and id like to be a game programmer someday and you really helped me get ahead of what i should learn when studying.

thanks i can make m own boxes with int and stuff very much aprreaciated

[imnota5]

@thehumor

you have same goal as me =)

[themightyleo]

stupid curiosity question. could you say

int 9; ?

or is that not right?

[cplusplusish]

@themightyleo No, numbers cannot be used at the start of a variable name.

[2milehigh]

Thanks, I'm still following you! takes a little time to get back into it... but I'm slowly learning. Thanks man, see you on the next video!

[phishitaac]

ty very much for your hard work on these videos..

[JacktheMan1199]

I am trying to make one variable, k, divide by another, d. I am doing this for another variable so heres what I have. int k; int d; int r; k = 13 d = 18 r = k/d For "r" I also tried k / d with spaces, but, no luck. Can you help me? *Those Variables do stand for Kills, Deaths, and Ratio. I'm making a FPS. This is for the score board. Ohh, and antiRTFM, Great videos. I was told about you by my friend The Floating Brain

[activeellis]

At the end of the day At the end of the day At the end of the day At the end of the day

[joaolggross]

test it =P

[DaBlackIce1]

Your tutorials are really good :) Thanks a lot, it has been really helpful.

Instead of saying that a left value or right value "yields" something...I would say it "evaluates" to something. Not really important thing though, I completely get your idea. Once again thanks!

[TehPheonixmaster]

You're such a great teacher! You make everything so simple and clear! I never realized how similar C++ is to Lua 5.1

[Duffinator22]

Wow.. completely worthless episode. My suggestion for anyone about to watch this is Don't, just skip ahead to episode 11 unless of course you want to hear him repeat the word "Yields" about a hundred times... >_>

[brokenbylaw2]

He is explaining it, rather teaching it. i have been developing in c++ longer than you've probably known about it, and with all those years, i still find this accurate and actually needed in a teaching basis.

this is informative, and it explains ibdepth rather than telling you what to do.

[zingmars]

@brokenbylaw2 yeah, while he doesn't really explain all the things correctly, he still does it. I remmember Buzz3D C++ tutorial. little explaining, and alot of - write that, and that.

[Nick0rz]

Haha seeing how C++ works make learning the quick and dirty way of VB is very dangerous for future learning :P

[DAROMSninja]

I sat through this with my mouth open, dreaming about unicorns.

[TheMuffin100]

cool

[benblue3]

how do i make it so y = 3 or 2? i forget what video that is and i dont want to watch them over again

[benblue3]

nvm i got it

[IDOG321]

int y;

y = 3;

try that lol

[0121ryanh117]

@benblue3 By learning how assignment operators work i.e =

[holyarmda]

lol int x =9*9;

r=t*y=x

made my brain hurt ... great vid u healp me under stand c++ veary well

[CodingKid]

your videos help me a lot. I'm on my way to creating a calculator for myself :)

I'll put you in the splash screen when it starts.

[LindenNolet]

At the end of the day, this video yields "awesome"

[CorruptProCA]

Great Videos. Just to know will you get a simple game and just show us, you hacking that game? Please I really want to see you in action and understand that concept.

[tehepicasian]

@CorruptProCA

If you are getting into programming just to "hack" a game, i don't think you should be learning to program...I'm not trying to be a douche, but I've seen on a lot of forums not to do it...

sorry if i seemed like a douche,

EpicAsian

[thenextorion]

wow...Its 1am in the morning. I just sat here, and watched 10 of your videos in a row!. Ive been trying to learn c++ since i was a kid. But I just afford the books, and online material is hard to sift thru, you really do a nice job at covering the possible questions. Thank you so much. Im so excited to be learning a language.

[Punniabi]

r = t * y = x;

is that even legal?

[antiRTFM]

nope, see video info

[Punniabi]

oh sorry man I didnt read it.. i dont like reading i like to hear people talk by the way man your a good man you explain stuff so slow and it helps people like me with ADHD and you explain common sense stuff which you cant even learn in school because teachers assume everyone already knows it.. ya man keep up the good work

[TripleHfan54]

@Punniabi Fucking nerd

[TripleHfan54]

Fucking nerd 

[Punniabi]

@TripleHfan54 You're just mad that you were born stupid :( and I am happy that I am smart :)

[MrNooblie]

@Punniabi it is an example, i am sure with the right expressions one can ues this example

[62628282]

OMG...u explain it very well eaven my little 12 yers old bro understand it lol

[mubeen316]

at the end of the day lol

[potroexl]

lol

[cuffyx]

This is a very good tutorial... Explained simply, 10/10 Thankyou.... 07

[EndaCraig]

Fantastic tutorials, a big thank you from Ireland.

[lilwarthog]

THE BEST TUTORIALS ANYWHERE YOU RULE!

[leviterande]

HI man, I really cannot thank you enough! this is much better than books to start with, you are from russia?

[VolureDarkAngel]

ok you have a good way of expressing your information. however your information is not correct. Your teaching people the wrong terms. an expression is something that yields a result and a statement is any valid line of c++ code. Each line in your program that ends in a terminating semicolon is a c++ statement.

and those keywords you are saying are invented. are functions. not keywords. keywords are basic c++ instructions. they are basic c++ commands. Functions are lists of instructions.

[antiRTFM]

yep, thats why there's corrections (see video info) and updates. Thanks for your input!

[robosky03]

This was the most simple, direct definition of 'lvalue' that I have seen. Thanks!

[Joeinnes0]

Perfect Tutorial :D

5 Star mate! *****

Love your tutorials

[jurtin3]

what do u mean with ur imperfect english lol? if u asked me i d say u speak english better than english queen xD

[ctoon6]

lolz you should be a teacher, a lot of them just throw a text book at you and expect you to do an exam at the end of the semester consisting of making some sort of useful app with a GUI and stuff.

[leviterande]

its always like that man, teachers dont know a shit and people like this man that really explains are not working as teachers

[TheWesselbross]

you're the best teacher in C++ ever, the first one who could make me understand C++

[DKeller4113]

wow I'm only 14, and I was interested in c++ lately. I've looked all over for simple beginer tutorials, but even the easiest of the easy made no sense. but your videos are so clear, so simple, that every detail you've explained so far makes complete sense. great job on these videos, you're really a great teacher =D

[antiRTFM]

thanks!

see my channel FAQ #1

[WTFOWN3D]

So what if he is? Does it make any difference?

[TledgEs]

Quite simply put,

if you put

9 = x;

x will not = 9;

hes just trying to explain how the placement of the variables matters

[efrog57]

i really didnt get the point on watching this, maybe its just to clear things up. Keep up with your vids!

[antiRTFM]

yup

as the video starts off, its "An important concept to understand in c++" :)

[babyaiko]

Legend :D

[tantoebatty1]

This is the hardest till now for me... have watched it 3 times now, still dont get it. lets watch it for the fourth time now :P

[jeezcak3]

if you were serious, programming is not for you. ;]]

[12nick345678]

It says any number cant be on the left sie of the =

9 cant equal 5, or anything else, on the other hand x can equal 9, or anything else, So it can be placed on the left side of the =

[Jethar2]

lol, u ramble sooo much. but its good hearing the same thing 3 different ways.. helps it sink in. thank you for the hard work :)

[MEGADETH155]

i cant imagin that i can actully learn c++ with out your videos!

[EYEdROP0]

wow man, excellent video again.

[Sadlez]

so an expression is anything that has an usable value? (a value that has the possibility of being used.)

[antiRTFM]

yup

[00pedro00]

exelent

[skateprojosh]

when i try to download c++ i get an error saying 1935 something blah blah blah error what do i do?

[danielghofrani]

what happens when you say r = t * y = x ;

it sets r equal to x but what happens between t and y?

[antiRTFM]

in C++ there are rules of "precedence" meaning which operator (+ or * or = etc) gets operated before others. But since it could be hard to remember all the rules, also since you'd want to be as clear as possible in your code, use parenthesis as much as possible. See video 17 about how parenthesis can force operations to happen in whichever order YOU would like

[danielghofrani]

no I mean if x is 30

from that operation it is clear that r= 30

but t and y can be all of these integers (t,y) or (y,t)=(1,30)(2,15)(3,10)(5,6) a

[antiRTFM]

not sure i understand what you mean... when you say "(t,y) or (y,t)=(1,30)(2,15)(3,10)(5,6)" is that c++ code your intending or pseudo-code (example code)? and by the way, "r = t * y = x ;" causes a compiler error since the * operator has precedence, so its like saying r = 1 * 2 = x; as you see from the '1' till the ';' we are trying to assign x to a rvalue (1*3).

[danieldraco2000]

I am talking about 07 : 25 where you type int x=9; r= y*t=x ; well it is clear that x is equal to 9 and it is on the right so it sets r equal to 9 but what does it set t and r equal to? well you havne declared the other variables yet, imagine that you said int x =4 ; int r,t,y ; r= y * t =x what does it do know? well it sets r equal to x but what happens to y and t?

[antiRTFM]

(part 1)

(you probably meant to say "...and it is on the right so it sets y equal to 9..."

1: correct, when i started using r y and t it was just an example of some variable you would already have declared somewhere before.

2: See the video info. If we use the code in the video info, we get like this: x and y are both the same number (in our case 9), t will stay whatever it was before, r will be whatever-t-is times x.

(hm why cant i reply another comment? maybe you need to reply something first)
