C++ Tutorial (22) - Absolute n00b spoonfeed

[iExD]

WHOOT!!! Finally , the awesome code of "loops". :D

[Zonde32]

where is 20 and 21?

[masteroforkut]

The best!

[LordOfMedusa]

could you use ==2 or another int to increase by more than one

[hjjais]

@LordOfMedusa it wouldnt be ==2. it would be

for ( int i = 0;

i < 10;

i+=2

){}

Sry had to separate it because youtube doesn't allow code

[BboySpikey]

for some reason every time i go to sleep since i watched this video i hear countless whispers inside my ear "hello world...!" x_x

[SirStrum]

Wonderful stuff man... Very helpful!

[Kizzurazzgabi]

Is there any way to have a variable specified BEFORE the loop? like if you have the user write a # then that number is the number of times the loop reruns?

[Vortigon]

Im a bit stuck.. why doesn't this display a list of numbers as it counts up?

int main()

{ for (int counter = 0; counter <10; counter++ ); { cout << counter; cout << "\n"; }

missed out the normal extra stuff to save space..

[limp1t]

@Vortigon

The problem is the third semicolon. After the for() you should have the block {...}.

What the third semicolon is doing is ending the for() expression (when in fact you're not done yet, you want to put code in it).

[babuks82]

Amazing, very good. Everytime u mention of more info videos on the right section for practice. But can't find any with the title u mentioned.

Is there a possibility of having ur video tutorial cos my internet is slow so i would like to save them for future reference. Thanks mate

[MrStefan124]

Great tutorial! And your english is good.

[xXxDiukexXx]

I can make that everytime it loops it call a function? like this:

for (int = x; x <100; MyFunc(); && x ++)?

this would spam MyFunc(); 100 times right?

[skoushik333]

Just curious. The text will be displayed 99 times right?.. since you gave "counter < 100" .. i guess if it were "counter <= 100" .. it would've displayed 100 times..

[tahayassen]

@skoushik333 No, it will be displayed 100 times, because the counter starts at 0, not 1.

[skoushik333]

@tahayassen Ah.. I see.. Thanks for the reply :-)

[mistahowe]

what is the advantage of  a for loop as opposed to a while or do while loop?

[tahayassen]

@mistahowe It's mainly preference. Most programmers use for loops to do counters, and use other looping necessities with while loops.

[Falconimator]

Small correction for the start:

Video information is now, thanks to youtube, below the video.

To the right of the video are some advertisements we all hate.

[the6aces]

what was the forum's name again ?

[antiRTFM]

@the6aces see video info

[arcaniumb]

Hi antiRTFM there is a semicon after 9, Is it mistake?

[0121ryanh117]

@arcaniumb What 9?

[mojbrenalog]

Hello antiRTFM!!! This video is excellent and I enjoy it.

I already know some C++ but this makes learning easier for me cause I'm visual learner. However, I can't find the practices that you are referring to in video #22. Is it still available?

[89myacc]

I really enjoyed the videos up untill now Anyway I had a question when I use counter + 1 instead of ++ the loope is infinite. Why can't you use + 1.

[antiRTFM]

1) you probably didnt assign anything to your 'counter' yet so it acts crazy. Never use a variable before initializing it with a value!

2) "counter + 1" will never keep counting up higher and higher until its time to stop. the ++ operator counts it up.

[iam4eversmart88]

@89myacc  you can use +1

[TEHSOULREAPER]

@89myacc to do it like that you need counter=counter+1

[skimo9000]

i have inserted 2 conditions in the loop one of them been ignored

[antiRTFM]

see my channel FAQ #3 and #2

[gamma526]

it would be funny if you named the counter variable "C" then it would have been

for ( int = C ; C<100 ; C++)

[0121ryanh117]

you could name the counter variable c, no reason why you cant.

[deadleg22]

lol possibly the geekiest joke ever. points++

[MeneerJK]

that was epic, gamma XD

[hjjais]

@gamma526 you mean int C = 0

-_-

[kopilatis12321]

isnt loop the very basic foundation for game creation ?

[Farzher]

Yeah, but not this kind of loop, for loops go instantly all in one frame, you need a loop that goes once every frame.

Not sure how to do that in c++

[0121ryanh117]

Im curious, what do you mean "you need a loop that goes once every frame."?

[tubby775]

You type in a 100000000 for one of those and you made an exe that can give someone a seizure.... Funny funny funny funny funny lololol

[babyaiko]

Legend :D!

[markyehia]

i didnt know uptill now, what's the difference between a float and a double i cout them 1.23456789, and the float gave me like the double, which is 1.234567, i need an answer asap thx nice videos u r a GREAT teacher !!!

[AlienInsect]

doesnt work in Dev C++

[antiRTFM]

what doesn't?

and by the way, Dev C++ is widely looked down upon for countless reasons, especially when we have the free Visual C++ Express for PC and Xcode for MacOS

[AlienInsect]

I typed it out how it looks into the programmer and nothing ran it gives me errors in the cout area

[antiRTFM]

see my channel's FAQ for your response;

code 3, code 2

[element1988]

i just use it coz its small

[Ninjasprayer]

it worked for me in Dev c++

[superjuice19]

im looping =)

[Sadlez]

So what's the difference between making a variable within a function, structure, union or a class's parenthesis and making them within their brackets?

[antiRTFM]

all have their purposes, as explained in the videos

[Sadlez]

I can't go on for today. pluss is thanks giving day so a break is ok.

[Ziphlon]

So what would happen if you typed.

[CODE]

for (const int counter = 0; counter < 10; counter++)

[/CODE]

Would this just loop forever or would there be an error?

[antiRTFM]

This code cannot compile because you cannot perform "++" upon a constant variable

[Ziphlon]

All right thanks a lot! I didn't want to run this and find it stuck in an infinite loop or something.

[jacarrdude]

Love your vids.

they are very helpfull

i was wondering if there was any reason why you use cin >>f; to keep the program up, instead of system("PAUSE"}

[antiRTFM]

system("pause"); is not standard C++ as you will see in future videos

[fkhalail]

In Tutorial 22 you are mentioning a forum where you have put some exercises. I am really not being able to find it. Would anyone please advise on that?

[antiRTFM]

its in the video info

(click on "more info")

[fkhalail]

Thank you so much for dedicating your time making these videos and sharing of your knowledge.

[ZayLong]

how log do you think it will take me to make a simple platform game with my currnt C++ knowledge? (this is the latest tutorial ive seen)

[antiRTFM]

harrumpf.... a long time :)

truth is, it all depends on what kind of game. you can begin making little text-based games now (see the forum for some examples), but huge 3D games will be another LONG time...

[maciphoneuser]

you are doing a great job!!! I'm learning so fast. I think it's even better that my class in Miami Dade college.

I really appreciate what you are doing!!!!

Thanks.

[lambda30]

thanks, and keep it going :) !

[pointblank941]

do you think you will get to pointers somewhere in your videos

[antiRTFM]

sure. i am thinking of making it my next video (#41) im just trying to figure out how ro make YouTube HQ vids...

[MihaelaAchiroaie]

i think it has the HQ option when you record it on a bigger resolution. ( from what i've seen on my videos) A movie of 640x480 and bigger, uploaded on youtube, should have the hq option.

[danielghofrani]

can you break or exit the loop somewhere inside the { } ? with using an if statement inside?

[antiRTFM]

yes, as we will learn about the 'break' statement
