So nice to view this before my exam! Your video's are always well explained and short enough for my attention span :)
did you pass the exam
It _will_ get better for you. Seeking success while yearning for failure is literally the most Giga Chad mindset you can have as a learner. In theory, it addresses anxiety by having the individual understand that the thing anxiety obsesses over is exactly what a learner should strive for. Look up some quotes on science and ignorance, and you'll be well on your way to schizo-town, like me.
*Haha, now you're shizo!* sorry I hope you're not schizophrenic.
suprisingly not an indian man but still pretty good.
Hahaha totally agree with u 😆
😂😂😂i was looking for this
💀💀😂
YESSSS
😂😂😂
Got 27/30 on final exam because of you thank you bro!
I’m really tryna get like u bro, had to retake my c++ class and hopefully I get a better end result this semester
where did the 3 marks go?
In some book about Python (which also starts indexing with 0) the author wrote, that zero'th position is because machine thinks of a movement of an indicator.
it is 0, because the indicator did not move, he is in starting (0) position. so when you select an index, in Python or C, you think of a pointer, indicator, or "a needle", that moves (or not).
A needle is a metaphor, but I think it is close to how it works under the hood.
much more understandable than my collage lectures
Thanks for helping me Sir
Finally an account that’s NOT Indian. 🙏🏼
wdym..?
Please make a series on x86 Assembly language. Or include some videos on Assembly in vids for other languages like C, that support in-line Assembly. Technically, x86 Assembly (32 bit) is not the same as x64 Assembly (64 bit), so I don’t know how it would work for you, but it would definitely be appreciated by the community!
Excellent
Good lesson, thanks. I'm glad I subscribed.
Nicely done mate
Nyc❤
awesome!!!
thanks broski, supplementing CS50 with this because some concepts really go r/whoosh
Thank you so much!
whats anoying is that an array is a pointer, i would really enjoy if u did a video about that, need to understand pointers better
Just learning C atm, can anyone tell me why you would use "double" instead of "float" for a money value which only runs to 2 decimal places like the example here? I know it's more accurate for long numbers but if you're only getting 2 dp values what's the advantage?
You are right there isn't an advantage unless you are using a really long number

Which extension do you use for C on VS code?
*c
Hello, I have some delightful news that will brighten your day!

bro printed my wallet 💀
Thx!
This video is just simplicity
Thank you!!!!!!
❤❤DONE❤❤
Here's some code I made with an array:
#include
#include
#include
#include
#include
int main(){
double height[2] = {72};
printf("How tall are you? (in inches)
");
scanf("%lf", &height[1]);
printf("
I am %.0lf inches tall, ", height[0]);
if(height[0] < height[1]){
printf("I am shorter than you by %.1lf inches.", height[1] - height[0]);
}
else if(height[0] > height[1]){
printf("I am taller than you by %.1lf inches.", height[0] - height[1]);
}
else{
printf("We're the exact same hight!");
}
}
thx man
whats the extension you are using that pops up descriptive code line in a box?

I thought print is only for python ?
Printf("Hello World! " ) ;
Thanks. Is there any type of print function for c++ apart from cout
What happens if he print the array with no value
It would be uninitialised so there would be an error
When you initialize an array, you are grabbing a continuous block of memory on the stack.
int arr[3];
In this declaration, arr is set to the address in memory of the start of the block of memory you have grabbed. So arr* is the same thing as arr[0], they both point to the start of the memory block.
In this case, the size of each block of memory is of size int.
If you don’t set arr[0] to a value before printing it out, then whatever existed there in memory still lives there, we haven’t overwritten it and it’s not an error to print it out. We refer to it as an ‘indeterminate value’ otherwise known as ‘junk’. So if you print it out as an int, then you’ll just see the int representation of whatever data was at that location of memory.
The fact that data can persist in memory even after we have stopped referencing it can sometimes be exploited by hackers in an exploit called a ‘Memory Dump Analysis’ where they analyze the memory to find sensitive information that was not properly cleared from memory.
my gcc does not accept [] without value, error no dimension specified. Which program are using? under linux?
Vs community I think
