For those who don't know, he's Bjarne Stroustrup, he developed C++.
Wow we did not knew that you are such a genius
Wow.. I didn't know that.. Wow
@@egretfx yeah, he is the father of c++
@@wbhtrb3008 yah he's like, he did, he gave birth to C++ litearly
@@jakubsebek yeah ofc, Dennis Ritchie would be proud of his grandson..
This makes me feel good. I love C++ and everybody tries to push me towards python or Java, but cpp is so awesome.
yep its way too awesome :D and superior in every fuckin way :D
@@rickarmbruster8788 Same, I love CPP, java is good too. But I want to code in C++ FOREVER
python is for beginners in programming. Java is the most used in the world
@@ugochanneltv5600 plebs are the most common in the world, if you cant tell why plebs use java or similar languages depending on runtime enviroments and interpreters. You are a pleb, if you denie it, you betray yourself and the world. I wont do that, i use C/C++ its not only faster its secure, it keeps integrity. If you believe Oracle and Microsoft wouldnt betray, spy and take advantage of your runtime, you are a moron.
@@rickarmbruster8788 you don't need to use words like 'moron' when you argue...learn some respect
I thought debugging Python code was horrible because of the lack of type constraints, but reading C++ error messages got me years closer to the grave.
Try debugging java errors, especially while using web frameworks
as an electronic enthusiast who works mostly with c++ and assembly, i feel ya mate but its worth it since you get so much control over what your doing
@@tylerdurden9083 try debugging SQL errors, they don't even make any sense
As long as you know what you are doing, you will know where the error lies.
@@mtb2625 well yea, but isn't that the point? Error messages are the most important precisely when i *don't* quite know what I'm doing : p
This old man should learn c++ for sure. He sounds interested in c++.
Right? I think that he would love that! Maybe he would even contribute to the language a little bit? Who knows...

How to find what languages/technology you should use:
1. Find an industry you enjoy
2. Find a job you would like to do in that industry
3. Look at what languages/technologies that job requires
4. Learn those languages/technologies
You can earn money and create incredible solutions with any language, so don't focus on the language, focus on what you want to do.
People too often start learning a language and then find out it won’t even be used in something they’re interested in.
Thanks for the suggestions! Very helpful for beginners like me.
You said the secret buddy 🤘🏽
@@HypnosisBear is it true that if you learn the logic behind coding and learn one language, it will be easier to learn other languages later on?
@@eLTIMIMI yes it is, once you have the logic it applies to all languages, and learning a new one becomes easier
@@eLTIMIMI yes it is! Only the syntax is different, logic behind programming is same for all languages.
C++ with it's meta programming is phenomenal. It's so powerful and so hard to learn and hard if possible to debug, all at the same time.
The learning curve of meta programming itself i'd say is so steep it puts down so many people from mastering it
i barely touched it yet :D but that will come in future
I discovered meta programming years ago, before I knew what it was called. It is very powerful. When you get deep into generic template development, it just appears naturally in your solutions. That is when you discover what the real weaknesses and strengths of the language are. I was very happy that C++11 started the process of eliminating some of those weaknesses and making TR1 part of the STL.
@@johnshaw6702 thanks for your comment
That’s why people should start with easier languages first. C isn’t that hard once you learn the basics, but it’s hard to learn the basics in a language like C.
Also use an Package manager if you are trying to learn C. Either the built in package manager in Linux or use something like vcpkg for windows and visual studio. Vcpkg basically let’s you just install libraries from a command prompt and it auto integrates them to visual studio as well as builds their dependencies automatically for you.
+1. I was shocked when I discovered that C++ can do meta programming
C++ is an easy languages to get into but definitely hard to master. If this is your first starting programming language then good for you because its cover the fundamental of most programming concept. Which is why learning Python & Java later were easier for me.
I agree C++ was also my first language and after knowing the basics the rest of the programming languages are way easier
c++ is no different from java or python, same collection of garbage features added to compiler with every patch, the only difference is that c++ is compiled and statically typed. The only reason I would not choose C instead of C++ would be support for various libraries.
C++ is most definitely not easy to get into
My first was python and I am currently learning C. At first it seem quite easy. Till loops everything seems so similar in two languages.
@@jeniosk1097 It is if you ignore memory management
I hope to get into columbia university for my masters and get to learn C++ from him! I love C++. BTW, he forgot that most deep learning technologies are also using C++ for computer vision and NLP tasks.

I may not like C++ (Python fanboy), but it is one of the best languages for gaming, robotics, hardware, and self-driving cars. Only way to avoid it is to avoid industries that use it.
Why c++ is more oriented for that and python for finance and dataa?
@@joaquinms8600 Hardeware and high speed gaming needs language closer to the processor and fewer abstractions to move fast.
Python is a higher level language with lots of abstractions, thus making it better for programers at the cost of speed. Since data is usually an internal need rather than a user need, Python is more useful in that area.
@@akin242002 "...an internal need rather than a user need..."
Thanks a lot for this statement, I've just understood EXACTLY and REALLY why a particular programming language is chosen over another one.
Note: Starting in programming and beginning with C++ (Bjarne's book).
Thanks again. And good luck to me🙂🤞🏽
You still use it
Deep Learning heavily uses C++, but it's completely useless to learn C++ for deep learning, because all of your programming is in python.
It's kind of like telling a mechanic to learn java, because his tools run on java.
I love C++ but haven't coded much in it. C++ is used in stock market, camera, cars and several other areas where data processing is involved.
True
great to see an old wise guy being a big fan of c++ and sharing his experiences! :-)
I mean he created C++ so it's logical he's a fan of it.
@@astrovation3281 Damn boomer
Maybe he was working with Java and then c++ changed his life. I wish he could learn more about c++ and create some life changing things.
I wonder if Bjarne had full hair before he had to debug c++ code. 🤣
That is correct. Numerical weather predictions also use C / C++ and fortran.
Its great to see, how he can talk and whistle at the same time 😂, No wonder that he invented c++
This man is a national treasure, you won't understand the beauty and power of C++ unless you have the desire to become a real programmer, it's as simple as that.
Drop that real programmer bullshit, FB is built on PHP, Instagram in Python, any language no matter how bad can make good software
Gatekeeping programming through c++ lol. There are dozens of other languages that "real programmers" use for all kinds of use cases.

It so cool to get this info from the inventor of C++ himself. Having said tht, each tool is relevant, one cant use a hammer where a screw driver is needed or a plier is needed.
Hammer or plier or a screw driver, ultimately it's the creation that matters more than the tools used to create it. No?
Where can I find the complete interview? I'm taking this nanodegree program right now
C++ is the most beautiful thing never made ... it is just like an omnipotente and omnipresent language, you can handle lowest and high level,.... used for everything you can imagine..
Indeed!
On my way of mastering it.🙂🤞🏽
Thank You very much
I love to play with pointer in C++ ❤️
I'm struggling with pointers in my C++ class rn :(
Just remember that a pointer is a variable holding an address. Technically it is just another integer type specific to addresses. The * just says goto that location in memory, where the data is, so I can read it. Therefore a pointer to a pointer is just a variable holding the address of a variable that holds the address of the location of the data. I am self taught and had a hard time with that one myself, but now I don't even think about it.
@@johnshaw6702 thanks a lot for your comment.
I'm a self-taught too, I'm two weeks in my programming journey, with C++.🙂🤞🏽
@@myownway07 Good for you.
Here's another for you. A reference is a type of pointer that is automatically dereference. What that means is that the compiler adds the * internally. If you name the pointer p (an indirect reference), then *p is a (direct) reference. The main advantage to using C++ references (not *p) is that the compiler ensures that a reference actually refers to something, while a pointer can point to any random address (if not assigned).
When in doubt, write small program to test your assumptions.
int data = 101:
int * p = &data; // A pointer to data
int ** pp = &p; // A pointer to pointer to data
int & r = data; // A C++ reference to data
// p = &r which is the address of data
cout
Looks like industries need to start teaching C++ more. Especially for students in the field of Data Science.
No way, why would you want to introduce complexity and tons of bugs when you can use higher lever languages for the main parts while calling c or c++ low leven implementation in a transparent way.
This is what happens with Python, which by design is going to be slow when doing intensive work, but it's not and that's why it's the most used language in AI and Data Science in general
I don't think so. Every ML / Data Science library in python is written in C++ with a python wrapper around it. Even the numpy library is pretty powerful I would say.
Not happening. Too much love for Python in Data science. It makes it too easy for non-programmers with PHD's in other fields to learn.
I think all universities have at least one C/C++ course as a core for a CS degree
@@bekchanovj that's correct. Most universities make you use C/C++ in at least 2 courses (Computer Organization/Architecture and Operating Systems). However, some schools make it their main language e.g. CS1, CS2 and then Data Structures & Algorithms.
one of most difficult languages but among most useful for difficult work.
Thank you
What a wise man
c++ is my first love, java and python I'm still learning, but C++ was definitely more enjoyable
He is amazing
cool video)
The man who create what we have now
Ahhhhh.... My first programming language ❣️❣️❣️❣️
This is a maestro
I tried Python, I can see the appeal. Dynamic typing is OK for learning and prototyping, but give me C++ and static typing any day for major commercial systems that will be maintainable.
I honestly don't know how people can trust dynamic typing in production code - I hate it, it's just begging to ruin your day at some point. Even in PowerShell I like to define variables properly - if I want an int, I want an int!
@@hermand Interpreter: "This variable can't be used as an Int!" Programmer: Casts it to Int. Interpreter: "This int is NaN (Not-A-Number)"
Static typing for the win.
I thought that was just me goofing around and there's some standard way of introducing type constraints in python code.
Spent a good week trying to reverse engineer python code I wanted to use for my bachelor thesis, because everything could be anything and it could be defined anywhere.
Funny thing about this man is that He looks exactly like how you imagine a creator of C++ would look like.
no further proof required. just one look and "yep he made c++"
Funny!
JavaScript itself is running on c++
What he forgets to mention is it is the go to language for programming microcontrollers. Applications range from simple home automations to controlling sophisticated machines like rovers. It is fast.
He doesn't forget, he created c++
@@denishpatel6038 of course

Stephen Merchant brother is so smart, thank you sir.
incidentally... majority of the embedded domain (specially 8 bit & 16bit controller) are still ruled by good old plain C... nothing can beat the performance of plain C. Cpp has a huge overheard for the features it brings in.. . worth only for larger memory & mips platforms
Well yeah, C++ is huge compared to C. It was not made for microcontrollers but for devices that can fully utilize it's power. On a modern PC the advantages C++ brings completely outweight the slight performance difference as compared to C. But in the world of Microcontrollers with very limited resources it's the other way around.
You have to be an engineer to write C++ for BMWs or almost all the things that he mentioned here. Don't think you can just learn the language and start programming vehicles. There's a wealth of other knowledge involved in that. You'll need to think about doing an engineering degree.
You need to have a good understanding of mathematics, IoT (microcontrollers), electricity/physics, etc. to write code for many vehicles these days. Most people in the field have Electrical Engineering, Computer Science or Computer Engineering Degrees.
@@MalamIbnMalam as an electronics enthusiast, yes knowing you way around basic electronics, or the hardware you are working on is absolutely mandatory, cuz when it comes to debugging, testing such code and since each hardware revision is unique there is no "getting used to it", but ngl its fun, messing with hardware + software is awesome as you are getting a physical product out of it
Actually there’s a lot of departments for writing software for cars, some do the stuff with the hardware, some do the networking, somr do the c++ hmi, some do service,.... You DO NOT have to know it all
@@MalamIbnMalam in short you need to inherit a high IQ from your parents, unless you have dumb parents which means you'll flip burgers

Definitely the image i imagine the one who created C++
And blokes go on asking to google "Is C++ a dying language ?"
Ha😂
They did the same thing with COBOL and FORTRAN, both, still used.... C/C++ Foundational language... I'm too stupid as of yet but getting there. Working Python and starting C soon. Strous, is the juice. I'll open myself up too whatever beatings come but? I built my killer little Pi station and found out, pretty quickly that i can get at and do anything I want on it, with Python, C and C++. I've only done a few small "hardware coding" projects but was stoked. I had never messed with hardware before. Good stuff.
Guess Cpp has its pluses
B. Stroustrup : "The self-driving cars, a lot of that work is in C++ too"
Me : *prays every second for no segfault to happen while on the road*
Just noticed he whistles while talking, now can't unhear it
All serous embedded systems seems to use C++. I see it a bit like Latin. It's a classic which will never go out of fashion.
Bjarn Stroustrup name randomly popped up in my head yesterday and I was wondering why do I know that name and messed up part is google seems to have read my mind, it just showed up on youtube today.
Everybody talking about how great cpp is but forget about c
Same with A and B
NO, JUST NO. I interchange C and C++ as if its a great vinagrett. We dont forget C.
People will not come around of C anyway, because most lowlevel stuff like WinAPI is written in C.
And when i say i love C++ i mean i love C/C++ inherently.
I bet i speak for alot of DEVs out there.
● C++ is better than C in term that it contains the C stuffs and also the object oriented programming features that C doesn't have + new libraries .
● C is better than C++ in terms that it is faster and light weight .

Start with python, and when you start feeling constrained, go to C.
@@myownway07 if you put a few weeks in python prototyping, you’ll learn C much faster. With c it will take you a year just to learn a good bit of the std library and the containers and system apis. Python will do most of that for you and just give you an easy text editor and easy function based library.
With C++ you have to deal with references and objects, and inheritance and math and all kinds of stuff. You aren’t gonna learn programming as fast as if you just sit down with something basic and learn your loops, functions, std api and strings and stuff

C++ is love.... ♥️ It's a way to get rid of the overuse of those shitty parentheses!
I am not a C++ programmer, but I believe in C++ and I know it will win.
Hmm, that's tough one... Perhaps at Guantanamo Bay detention camp?
Commenting in any form here ,nope. Just listening. With all due regards the new language evolution/ revolution after 2012 or so ,still very much ongoing vastly depends upon C++ : You just name it. Oh that LLVM...I think every body can relates the next... Personally I enjoyed C++ in every winning/ pathetic( both ways) ,for the last 26+ years. One thing stands out : if you really understand the fundamentals ( which are always ++ ) ,you can map and remap in any other systems oriented language or area quite easily, I think you know what I mean.My humble question to all here : except , LISP family , ML family and Erlang are there any area where C++ do not have something substantial? Thanks for the video.
Yes, with C you can do a lot more (and more complex) things but often we don't have time and there is the steep learning curve. We use LabView for some of these type of control development or prototyping and it can be waaay faster to develop and implement (and also to learn).
Can you please tell me more, where LabVIEW is used in practical world?..

That mouth whistle he does on every S sound is driving my dog to alcoholism.
C++ was a bit more sensible before the syntax explosion, template mania, and reuse of all bracketing operators for many different things. It's a disjointed language with too much syntactic noise and ambiguity. But if you like it, use what you like.
