Is there a reason that you used sizeof() to output the elements in the array? In my for loop I just had (int i = 0; i < guesses[i]; i ++) Is there something wrong with this way and that's why you didn't mention it? With this way it outputs everything in the array without the zeros you got when the size of the array was larger than the number of elements initialized.

[@chanelmuir9330]

if the values in your array are small enough the for-loop will end early.
Imagine an array with the values {12, 43, 23, 2, 23}
First you have i = 0:
i < guesses[i] evaluates to:
0 < guesses[0]
0 < 12
true
But once you get to i = 3
i < guesses[i] evaluates to
3 < guesses[3]
3 < 2
false
The for loop ends here as the conditions aren't met and and further values will be skipped.

[@chanelmuir9330]

to get all numbers before a zero to print out you could change the condition to guesses[i] > 0;
for (int i = 0; guesses[i] > 0; i++)
This would work as long as you know all of your values are positive non-zero integers, although once a zero is reached, any following values are skipped.

When you're a star they'll let you do it. You can do anything.. Grab 'em by the index. You can do anything.

Could you also make a video regarding c-strings using char arrays. You already have this amazing video and also on c++ strings using std::string. Im new to c++ and i think there is really a need for a actual video with char arrays and c-strings and how they differ from c++ strings and it would also show a different usage of arrays :-) . Thanks for all of your videos

[@liampapavasiliou9658]

I would guess that there is something like this in his c tutorials

Also. Thank you, you are helping me pass college...hopefully

[@PunmasterSTP]

How’s it going?

[@mhero9255]

@@PunmasterSTP not bad. Failed programing tho

[@PunmasterSTP]

@@mhero9255 I’m glad college is going alright, and I’m sorry to hear about programming. I never did much with coding myself; pretty much just playing around and tutoring. Java was the first thing I used back in high school, so that’s probably what I’m most comfortable with.

[@mhero9255]

@@PunmasterSTP thanks. But it's fine. And I would like to learn java. I was started off with C++ for some reason

[@PunmasterSTP]

@@mhero9255 I took AP comp sci in my senior year in high school and that’s where I started with Java. I heard that that was the first year it used Java; before that it was C++.
A few weeks ago, I came across coding and computing playlists made by a professor, including this one on Java ( ruclips.net/p/PLlr7Jt5dPiv6uNsAHqOpcCZq8qJF6_rA8 ). I’m also planning to check out the rest of Caleb’s playlist when I finish this one and then have the time to do it.

[@jeezygarceezy]

So what about user defined sizes?
Enter n;
Arr[n];
Int I = 0; I < n... You get the idea. I'm going through the Gaddis book and I'm on chapter 6 right now and seem to be having no problem not having the size set before compile. Is that something my IDE is fixing without me knowing?

[@omarramadan5261]

How come in the for loop the index of the array represented as i, despite having already incremented to the value 1, still shows the integer at index value 0?

[@bahrant3]

does the comma not have any value in the array

[@jalalshah185]

why system("cls") is not working in xcode

[@cynthialucien1926]

5:00 why is the output 413 when you're outputting guesses [0]?

[@messsymessiah4170]

I know I'm a few days late but here goes.
Originally he assigns guesses[0] to be 10;
Then he overrides that to be a number that the user inserted using cin. Since he entered 413 guesses[0] became 413.

[@quickfoods_qf]

Well explained

Hello, this was a helpful video.
I'm an astrophysics major. I am familiar with Python but I need help with C++.
I need help reading and plotting data from star and galaxy files. Ex. I may have a file with hundreds of stars and 3 columns; say distance, B-mag and temp.
How can I read the file then plot it? Do I need Gnuplot and can I plot it in my code? I use Visual Studio
