Lecture 4 | Programming Abstractions (Stanford)

[shayan915]

@Thetranslatorguy yes i agree , Mehran Sahami is far better , i hope he hold the course some day

[martmelee]

what IDE is she using in her lectures?

[shayan915]

@martmelee: Xcode 3

[codeXmith2010]

can anyone fucking help me with warezing C++ Primer by Lippman, plz send me a private message

[codeXmith2010]

what standard libraries i should include instead of genlib.h or simpio.h

[joinedfor1comment]

@ Julie Zelenski: It is obvious you are knowledgeable and intelligent, but when you dumb things down for beginners you should explain you are doing that to them. Made up stories about why fstreams take c strings make you look dumb. It is also frustrating to students when one day they are told things they assumed to be true actually were just simplifications of the truth(think of some bad instructors for middle/high school math). Hope rest of lectures get better.

[adelle0001]

nice lecture!

[agapitoflores001]

Very good lecture. The prof is really very knowledgeable.

[SaschaHeylik]

Not a good example... by convention, Class() es are starting with an uppercase letter, and function() s with a lower case letter.

[dashiellv]

Seems this course isn't for me. I can't get the course headers included. not with g++ -I /full/path/stanford_dir and not with g++ -include /full/path/to/simpio.h (and to genlib). I can't get it to compile even if I copy the headers and the private dir to the dir with my program. I still get undefined reference to `GetLine()' and such.

[dashiellv]

I'm using archlinux, g++ in a terminal and vim/emacs. How do I include these special libraries if I keep them in a folder of their own? symlinks? compiler options? Is is possible to do the assignments without the IDE-specific files? (like .vcproj .suo .sln .XML) I'm not going to "right-click on a file".

Haha, I just asked for support in a youtube comment!

[MegaCrazyJB]

I think I love her



[gatraw]

I wish the camera man would loose interest in her and keep the damn camera on the screen, we do not need to see her awesome hand movements and physique

[MrStanly09]

can anyone tell me how to add 106B library in xcode????

[selfdealloc]

@MrStanly09 Download and import it .

[eungomi]

@MrStanly09 Download the Xcode library from the site and install it. You will find Standford project when you attempt to create new project. If you get a compile error saying cannot find the SDK, right click on the project file from the Groups & Files explorer(or click info button from the toolbar), Get info -> Build tab -> change Base SDK to "Current Mac OS"

[omahdezavalos]

I find her super savvy and super attractive, god bless her, we need this chick around in u_tube to teach us stupid dude so we can learn something....

[Alimistar]

Wait, maybe I'm missing something but only a third of the class has even installed the compiler by the 4th lecture? Wouldn't you want to be done that by the 2nd lecture?

[BestTypoEver]

@Alimistar The first few lectures are just a review of C++, technically you don't need your compiler until the assignment is due...

[Alimistar]

@BestTypoEver Ah ok, that makes sense. Thanks

[muhamedkhan]

after MEHRAN SAHAMI, now there is again good teacher from Standford@@

[hmk9221]

thanks standford

[mylastnameiskhan]

nice pace and teaacher

[stm666]

How come she doesn't need to use "using namespace std;" for the iostream at 17:00?

[tibnor88]

@stm666 if you open genlib.h it is written there on line 26

[FrankRizzo6662]

Because it pollutes the namespace when you start adding everything when you only need a few things.

[YeahyeahIndeed]

Good one...

But I don't understand why they have implemented the "Vector".

In C++ there's a standard library called deque which does basically the same thing but with more functionality....And it is a standard, AND it is probably safer ;)

[aisbaa]

In my opinion:

to learn how vectors are writen.

why deque - to reveal details of deque.

[d1sfunct]

I believe that the professor's answer to the question at 14:52 is incorrect. As you can and will do things like while (getline(...)) {...} which checks the error code from the function return and not from the stream fail() call.

[Pontifican]

screw you guys, i love her fast pace.

[selfdealloc]

@Pontifican call

[arran5498]

Does anybody know if Mehran Sahami has got any other lectures on youtube apart from CS106A? Thanks in advance!

[dupreee27]

does anybody know that there's a *search* bar in upper right corner of this window??

[mailbvk]

I dont think so. I really wanted to see his Discrete Maths videos. But apart from 106a, I dont think any other lectures are available publicly.

[heavsar]

i think she gonna take a xanax so she will talk slower

[Lolluthegreat]

Good

[drb021]

The students in this class are just getting used to the C++ specifics, they have programming experience in Java. And your example was just bad.

[eddiekoski]

After you learn C++ and make a multimillion Dollar program then you can divorce.
