C++ in 100 Seconds

C++ or C-plus-plus or Cpp is an extremely popular object-oriented programming language. Created in 1979, today it powers game engines, databases, compilers, embedded systems, desktop software, and much of our software infrastructure.

C++ is like Lego. You can assemble the castle of your dreams, or you can scream in pain as you step on the pieces scattered on the floor

In C++ we don't say "Missing asterisk" we say "error C2664: 'void std::vector<block, std::allocator<_Ty>>::push_back(const block &)': cannot convert argument 1 from to 'block &&'"

I'm about 2 weeks now in my journey of learning C++ and freeRTOS for programming some ESP32s, and from a JS/Python person POV it's a whole new perspective, you really feel like you are controlling a computer down to the bare metal for the first time. I think every programming enthusiast should try it. Especially with something like a microcontroller where you really need to care about the stack/heap and living inside of a few 100k of ram.

Couldn’t fit operator overloading into 100s? 😉

C++ is a huge language. I've been doing C++ professionally for 15 years and still learn new things all the time.

C++ is my first language and it's really fun to learn. It also made learning other languages very easy.

C++ of 2022, is EXTREMELY different to C++ of 20+ years ago. Now it has extremely high level libraries on the DEFAULT spec so you can do things that any extremely high level language like python did by default (like text parsing) and I think if it had those features from the start dozens of popular languages would not even EXIST.

The benefits of unique pointers are not to only allocate something once, it's more about making sure a resource is only deallocated once as it will call the underlying objects destructor when it goes out of scope together with the fact that it can only have a single owner.

c++ having a string library means everything. Having done a course in Operating Systems that was C and that's it, having to manually write string manipulation functions was quite tedious. Not impossible or incredibly difficult, but felt like reinventing the wheel.

The double colon operator (::) that's used to define functions outside the class is called the Scope Resolution Operator.

My first, relatively big project I wrote in C++ was a Raytracer! Was (and still is) one of my most favourite projects to date!
Awesome video as always, well written, spoken, and very informative!

Thanks Jeff!

It’s funny how, even with as much as you covered in as much detail as you can in 165 seconds, the language has evolved so much that discussing templates, lambdas, the ranges library and functional patterns in addition to everything you covered would mean anyone would have to go at “rap god” just to get through it all in the small timeframe. Relay impressed on the level of detail you did go to for this video. Excellent job, love your work! Looking forward to the next one.

"using namespace std;" is kind of an anti-pattern. It's almost like saying "import *" in Python. You code becomes more terse, but now you can't tell if a keyword is builtin or from the namespace (or from the other namespace you 'used'/imported). And never put this in a header file, it'll hose anyone who includes your header.

C++ was created as a superset of C but they have diverged since.

[thehellberg]

You literally explained the Sololearn C++ course in a hundred seconds

[wojtekpolska]

In school they showed us basics of a few different programming languages, and i think C++ was my personal favourite out of all of them, i hope to learn more of it in the future

Could you do Lua in 100 Seconds next, please?

Compiler Error - > Syntax Error

Minor gripe: at 1:22, we don't call that the "bitwise shift left" in this context, but the stream insertion operator, or steam operator. Operators can be overloaded in C++, but people try to keep it "usual".

[KushalChandar.]

'<<' is called an 'insertion' operator when used with cout.
