Bjarne Stroustrup - The Essence of C++

Bjarne Stroustrup, creator and developer of C++, delivers his talk entitled, The Essence of C++. Stroustrup has held distinguished posts at Texas A&M University and spent significant time in the Computer Science Departments of Cambridge, Columbia and Princeton.

C++ is the one of the world's most widely used technology languages and it has influenced newer languages such as C# and Java as well as older languages.

Recorded on 28 April 2014 at the University of Edinburgh's George Square Lecture Theatre.

Been reading a lot of Stroustrup C++ books and I love how crystal clear his explanations are. For every "but how would you...?" that pops up in your head he explains it right away in detail.

[maxwellstrange]

Such a smart guy, I love that he's concerned with the language being approachable to casual users as well.

[بهنامگلی]

I feel he is a gentelman and beside his efforts and talents his sincirity and honesty and simplicity is great.
I started learning c++ this year and 7 months now.
And within 7 month i read almost 7 reference books and after all i read his book it was very good experience and i think i am better now in designing and thinking than i was and only think helps me to keep forward is the solemn desire to solve one humanities problem and make the life better place for every one.

Bjarne is a legend! It is so nice to listen this intelligent man talk about the language that at some point back in time changed my life...

[TopShelfization]

I cannot thank this man enough for creating the only language I can comfortably express myself. The only language that comes close (for me) is probably ECMAScript.

[thebudkellyfiles]

A modern legend. Every time I struggle to understand C++ I think about him inventing it.

[gojalsewnath]

I never new this genius but I understand that he is capable of reading your mail at will and monitor your i/o at the same time. And I really like the way he has programmed his haircut, hair by hair! I don`t know much about programming, but somehow it was just cool to listen to him.

[greatsea]

I'll just throw this out there. Recently I started learning C++ and some C after having achieved some degree of proficiency in VBA Excel and Python and here is the deal: If you are serious about learning the 'science' of programming, that is programming at the conceptual level, then choose either C or C++ as at least one of the languages you are learning. ((I'm leaving aside for a moment the obvious importance of the functional languages.)) I had always read that Python(and even Java and C#) is easier but I had no reference for this until I started learning C++. Obviously it is not going to be practical for everyone but if you want to be a true student of procedural process then go for C or C++. It flexes your brain way more than the higher level stuff.

[eddieoconnor]

Love how this man can describe / explain things and make sense!

[kingofcastlechaos]

Great video UofE. My favorite quote starts at 07:36, and he nails it. Thank you sir for C++ and everything else!

[davizitopa]

I won't watch any of my teachers or preachers lecturing for more than 20 minutes. This is 1 hour and 40 minutes long and I don't think Dr. Stroustrup is a gifted orator, but I will watch it to the end. The difference is the level of respect, I don't think any other living man deserves quite as much respect from me than Dr. Stroustrup.

[dreamhollow]

I'm glad we are as connected as we are to be able to see this interview even if we are far, far away from Edinburgh.

[tahmina]

Omg ... watch his first videos "The Design of C++" then watch this. His speaking skills improved DRAMATICALLY! He's awesome.

[seektherapy]

Bjarne Stroustrup needs to speak more often. He is brilliant and very humble. Almost too humble because I have popped into IRC's C++ channel and defended him and his programming language many times. The programmers learning C++ in the channel seem to think they know more about his programming language the man who created it, ugh.... Irritating!

[ptrblz]

The man himself 🙂 c++ is a great language where you can basically overload anything, access data up to the memory level and it's super fast, it makes creating specific solutions a journey of creativity with the possible reward being great speed and memory usage.. so good to have it

[metalore]

When a James Bond villain gives a lecture on programming, I listen.

[MikkoRantalainen]

1:34:17 I think the best way forward would be to specify lots of old C++ features as deprecated and automatically generate a warning if deprecated feature is used. That would allow slowly removing parts of C++ that have better alternatives today.

[azynkron]

Only a genius can make something complex and abstract to sound simple.
