It’s not asking me for starting population Comment from : will valsien

My code gets an error on "while(start > end);" it says that start is an undeclared identifier :c Edit: i rewrote all the code from scratch and now it worked all of a sudden bshrug/b Comment from : Lost Marimo

Thanks for this! I have a question about minute 6:27: When creating the condition for the 'end' integer you wrote "while (start > end)" but instead you say that "end is greater than start", which makes more sense to me but the code works for you writing the opposite, so I am really confused, could you clarify that step please? Thanks!! Comment from : M G

Thanks! I almost had it, the year counter is what I was missing This course is a lot harder than I thought! Comment from : Sun

Hey guys, please notice that there is a mistake at 7:07 In this specific scenario you cannot use a dowhile loop as this would lead to a wrong output if starting population equals ending population You need to use a regular while loop Here is the explanation why this is the case: While loops repeat statements as long as the condition returns true If the condition does not return true in the first query, the while loop is not executed at all do while repeats statements until a condition no longer applies, ie becomes false in any case, however, once) Comment from : Tess S

why everyone insists on rounding the process of growth and decline for animals In reality,if there are fewer than nine animals and they grow by 1/12 each year, their population is guaranteed to increaseRounding off growth and decline for animals is unnecessary Use float for inUse 'float' for calculation and int for the final target and number of years Birth and death of animals are gradual and ongoing process Comment from : Discratoms Note

I just start CS50 and am completely new to all this thanks for the informative video Comment from : Chago Mullen

Thank you 😭🙏🏼 Comment from : DoubleAAnime

Thank you!!!! I've just started the CS50x course and I'm completely new to programming and am seriously struggling to the point that I'm losing hope that I'm even intelligent enough for this! But I will keep marching ahead From all the YouTube videos out there I found yours and I'm finally starting to understand a little You broke it down well and explained it much better and slower than the lectures in cs50! Thanks again :) Comment from : Lavender Meteorites

Thank you very much!! Comment from : Diana Zaguralska

Tks Veryyyy Much Comment from : Public AudioBooks

Tks for sharing knowledge Comment from : Public AudioBooks

Am I the only one actually super overwhelmed with this first lab in the whole course? I feel like the lectures 0 and 1 made a ton of sense and I understood everything he went over, but this very first lab problem feels incredibly difficult compared to what we've learned so far Comment from : jadedjimmy

Very nice video and nice explanation , i have a question , i want an honest answer , is this problem a bit hard how to approach it alone for someone that had none experience in this field? Cause for me was really hard to start alone with the TODO instructions only through your video i understood the actions that need to be taken , but still without your video i wouldnt be able to figure out how to approach and start and keep going Comment from : DBeagles00

You have to end with a regular while loop If you use a do while for the final loop it will still increment the years value if the start and end are the same since the do will execute before checking the while condition So if you want to end with the same population it will say that it will take a year Comment from : Troy Arledge

Thank you! Comment from : Simon3

What programming language is this Comment from : Nicholas Chepkut

Very helpful thank you so much man Comment from : Lefa Vilakazi

can we use a for loop ? Comment from : Vader007

Thx a lot buddy Comment from : El-Sayed El-Senosy

Have you ever try start size is same as ending size? I think it doesn't work for that situation correctly, the year will be 1 if start size is same as end year Comment from : Sharon Wang

bro can you make a tutorial how to submit cs50 assignment? Comment from : Macapagal Jerobin

Dude thank you for your explanation, I'm new to this and I was struggling to make the program add a year, also I did not know how to make the (do/while) loop on this last part, but as I said I'm a noob Comment from : Aldrik AB

Dude it's hard not to understand your explanations Keep it up please! Comment from : Easily Coded

Dude, so many things made sense after you explained them Thanks man, I appreciate the time you took to make these Comment from : Tbucky Films

Excellent video! The one error I keep getting isbr ":( handles same starting and ending sizesbr expected "Years: 0", not "Years: 1""brI was wondering if this could be avoided by changing line 32 to some form of "while start is less than or equal to end"? Comment from : DaveyBaby
