How to DEBUG C++ in VISUAL STUDIO

[@alijoyce2169]

You can feel that he really knows his stuff and spent years for it. I really appreciate how it is free for us to enjoy.

[@wolfsnow711]

800 record? You were so underrated back then, considering that even six years later you still have the best C++ tutorial. The most precise, practical, professional, up-to-date and easy to understand. And you are so passionate in these videos too! I've had a headache trying to learn C++, because they only teach what the code means and how to set up the tools for compiling, but give no understanding of how it actually works top-down. It's so hard to grasp the process without CS education, I wasn't really learning and coding most of the time, but collecting scraps of information from different materials trying to build the image of how a process should work. But after your vids about compiler & linker I'm so fired up! I finally know what I'm doing when I write the code. I can't thank you enough!

[@02quocanh7]

Well, as a person who is having CS education (and still doing good), I realized that what I know is... almost nothing, compared with KZbin academy in general and specifically in this series. Got to say that I also feel the same, and it helped me a lot, as now I really understand how things work, at least now it make sense.

[@Dazed_04]

Another CS fellow here, still in first sem. I wanna say that I can write code that's sufficient for problem solving but even if I get it to work without copying someone else's code there's still that question in the back of my head "but why?". Why do things this way, what it actually means. The whole reason I like coding in general is the sort of magical feel you get when you build something out of nothing (it's not the instant gratification I chase I swear ;) . But then you get stuck on these questions and it's like someone took away that magic, like everything you're doing is using someone else's power(which is both true and not true). So these c++ videos are a treasure trove that just never ends.

wow i have a little bit of programming experience and this series has really helped me to understand the nitty gritty of the whole programming process. tysm for making this

[@daisonc.a.2472]

I always used print statements to check execution. Never thought that debugging could have be way easier than that. Thank you Cherno for teaching me how to debug.

[@steele.in.motion]

It's so great to find a series that teaches the way I learn. Thank you for the effort you put into this!

[@JohnnyThund3r]

This really is the best C++ tutorial on KZbin, I'm running through it again for the 2nd time because Cherno just knows how to teach you how to think like a programmer, even if you're not planning to use C++.

[@rcookie5128]

Debugging is love, debugging is life. haha for real: I partially enjoy debugging, its like solving a puzzle.. It can get reaaally frustrating some times, and sometimes even irritating, but over all its a key part of coding and learning to code better I think :)

[@jamesmnguyen]

ΜrCookie I once was using an external library and apparently my code kept crashing. Unfortunately I didn't trace it back to the library since the debugger told me a pointer was deconstructed (the class). After a few hours of hair pulling, I found out the library was manually calling the destructor.

[@warbossworm]

I find that the satisfaction of defeating a really nasty bug is one of the best feelings when coding!

[@Manas-co8wl]

It's also the most defeating... I mean it's always so easy in hindsight. Makes you rethink your belief in your prescience

[@Megalcristo2]

[@EldRiCkVis]

Ohhh my goodness. I can finally see what is going on in the background while writing code. Can’t believe I’ve been going to school for more than 2 years and nothing like this was ever mentioned.. how??? God bless you The Cherno

[@jmx808]

For those not well versed in VS17, Ctrl+F10 (or right-click Run-To Cursor) is a better way of moving from an existing point, to another point in the code (i.e., skip through a for loop)

[@slaozeren8742]

I have no experience in programming and I have been learning c++ for 4 days. I had to watch this video 3 times to fully understand it, but it was awesome. Thank you!

[@Andre-vn1sb]

I never saw a tutorial with so deep details, so you really understand whats going on inside mashine - thank you !!

[@annabelletrinh936]

For XCode users: - Memory View : ⌘⌥⇧M or through the Debug --> Debug Workflow --> View Memory menus. - Autos and Locals are available by clicking on the arrow at the very bottom of the debug console. - To Watch a variable: Right-click on a variable and click on "watch", or right-click on the debug console and click on "add expression"

[@sharwankumar-ci3hd]

Could you please guide me how to debug crash program?

[@marian3978]

Your timing is impeccable. Just when there's something I need to know like c++ header files or debugging in VS ( like today ) you upload a video on exactly that. Thanks!

[@vratislavi]

I think the fact I did not learn how to use the debugger caused that I didn't become a programmer, I used printfs to debug my programs on uni and it was very frustrating and stopped my progress a lot. It was not the only thing - I had different ideas about myself back, a lot of personal issues, but watching this episode right now after 15 years really hits a spot. Maybe I will return to programming :)

[@I_hate_HANDLES]

i wish i could watch this in my first year of university so that i would not be so frustrated debuging wrongly, now i am a little left behind🩼 but still very fun and helpful to watch

[@theseangle]

Imagine if you didn't stop, you'd have 15 years of experience, and that's like senior's grandsenior, you'd be rolling in cash 💀

[@ginsutime2963]

If you're getting random stuff instead of the cc groups, one of the things you can do to fix it is check to make sure you're on the same solution platform (x86). Switching from x64 to x86 fixed it for me.

[@spaidory874]

Yeah I couldn't see the memory it said (error reading string), then I changed from x64 to x86 and it worked, even though my computer says it has a x64 processor

[@Shah_Khan]

Any reason for that?

[@ginsutime2963]

@@Shah_Khan Here's a decent enough explanation I found: The absence of cc in the Memory 1 window on x64 is due to the architectural differences between x86 and x64, with the latter relying less on condition codes for control flow. You can still access condition codes in the Registers window during x64 debugging.

What's awsome is my favorite coding youtuber(you)just happens to have made a c++ tutorial series which I found as I decided to learn c++. not only is this series way more informative than any other series or video I have tried but it geared toward the one thing I wanted to learn c++ for in the first place... Game dav 😂🎉🎉🎉🎉🎉

[@wiiguy21]

15:30 - actually, at the end of the loop it will run i++ first, and then do the comparison to check if i < 5

[@mytech6779]

++i should increment before the comparison, i++ should compare then increment. Unless you are saying that i++ is the last part of the "for" statement and so i++ will increment at the end of each pass. Easy to test by printing i to the screen in the body of the loop.

[@pooria_garrett3020]

@@mytech6779 I just tested and what @Flaming Taco says is true.

[@tylerlowrey8854]

@@mytech6779 I know this is a really late reply, but this is incorrect. ++i and i++ don't make a difference in the header of a for loop (I believe this is because modern compilers optimize i++ to ++i). However when assigning a variable it does make a difference. If you have a variable x and its value is 7, when you do int j = ++x; the value of j will be set to 8 because the increment operator is applied to x before assignment. However, if you do int j = x++; then the value of j will be set to 7 because the value of x is assigned to j before it gets incremented.

[@NackySlocker]

I have found this to be accurate. I was watching i, and it said i was 4, but it was grayed out, apparently it becomes "undefined" after the for loop.

[@PsychadelicoDuck]

Seeing how easy Visual Studio makes breakpoints has sold me on it.

[@AdhyyanSekhsaria]

I think we are at a point where people who have no idea about programming have stopped watching. So there wouldn't be too much point in covering very basic stuff like for loops and if statements. Keep up the good work!

[@d3bbi339]

Adhyyan He gets to the bottom of everything. It creates a solid base to work from. You could learn something you had no idea you didn't know. It's worth the listen to me. But then again I'm still pretty new. Still here tho. I'm for real trying to learn this so I definitely appreciate the details. I get how it might get boring if you already know most of this but he did say at the beginning that he wanted to create a thorough c++ course that teaches people everything they need to know to create clean, fast code. So hey hey I'm still here don't ya dare take them details away from scrubs like me. Lol

[@pascalladal8125]

And yet, about no one noticed he got the order of execution wrong lol... it increments before checking the condition while he says that it checks then increments.

[@helgi7888]

if you can"t debug where you want just change setting of optimization(project properties->C/C++ ->Optimization-> Disable)

[@HelloFromTokyo]

Best C++ videos on youtube, love this series, hope there's more

[@ChyrosNX7]

Another neat feature in debugging is you can set a condition to only break when the condition has been met. Pretty useful inside loops where you don't want to break everytime it hits the breakpoint. I.e., # Break only when i == 5 for (int i = 0; i < 100; i++) { std::cout

[@roycinta3731]

Thanks for your work bro i learn a lot of your videos i never find a good tutorial fo visual studio and yours are the best regards

Quick question or maybe and idea for a future video: During debug at around 12:42 the memory view showed a perfect example of byte order, most significant, least significant bit and in general the architecture of the cpu coloured in red. Would be awseome for a future episode to talk about why it's written as "08 00 00 00" instead of "00 00 00 08". Love watching your videos, they refresh my memory a lot!

[@TheCherno]

Definitely going to cover that... eventually :)

Thank you for your reply, much appreciated!

[@bondymagnomous3544]

Isn't it big endian vs little endian?

[@justind6983]

they are read backwards

[@StarDDDude]

It is that bytes are saved in inverted order Your PC can only manipulate bytes (8bits) and not single bits Each byte has it's own place and name So when you wanna read a number that is bigger than a byte you will need to acces two "places" So let's assume we save F7 65 (this takes up 2 bytes, Hexadecimal is designed so that each number equals 4 bits so two make up one byte that's why they are speperated like this) in what is called FE0037 It will use FE0037 and the next one (in this case FE0038) to save the number But now what if we wanna read this in 8 bit instead of 16 bit mode (16 bit is when we use 2 byte, 8 when a single one) So let's read FE0037 (the smaller one) If it were saved in normal order we would end up with F7 which in no way equals F7 65. It equals that as much as 60 equals to 6054. Better it would be to get 65 which does have euqal the lower part of the number, just like how 54 is 6054 minus 6000. And that's why we save this 65 on the byte we accesed. It makes accessing that byte again in a different processing mode more logical instead of having to think about in what mode you were and from there count upwards to which byte you have to acces to get a somewhat logical representation.

I am not complaining as i am in the beginner stages of learning so, what would i know?. Anyways, liked and subscribed. P.S There is something about the cool color gradients and the soft music in the background of these videos that keeps me coming back.

[@kiranaric]

Just a point of note: You need to be in debug mode in order to open the memory window. It means you place a break point, start debugging and then go to the menu Debug -> Windows to see the Memory option. I couldn't find it and a simple search revealed this fact. When Cherno opened the memory window, he was already in the debug mode.
