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!!

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)

Life saver deserved a sub and like clear explanations thank god
Comment from : Oblivion YT

so i know I might be dumb here, but can anyone explain the math portion to me? I got my code to work, but I am confused how it gets 3 years
Comment from : Loaded Leader

What caught me off guard doing it myself is how the prompt word start with "if", because I thought it was easy just use simple statement but it was crazy when it show the hint section
Comment from : Brazzers Premium

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

is using this as assistance against the academic honesty policy?? i’d like to submit my work but i’m worried

Comment from : Vanisha Srinidhi K

I figured out everything except how to count the years which is the main part I guess Can anyone tell me why did he use loop to count it?
Comment from : Rudraksh Rankawat

Hello, I just started CS50 course thru EdX and I am having difficulty with running the population program Can you help me please How can I get you to see my cloud code terminal to see what is wrong? I keep getting a (built-in) Error
Comment from : Mark Turnquest

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 : 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

I just started CS50, and I've got to say your videos have been incredibly helpful Thank you for all that you do, and thank you for all of the time you spend helping the rest of us!
Comment from : Kellie Ely

Comment from : daniel Felipe Rodriguez Ruseria

Esse cara é show! Consegui fazer o algoritmo em Portugol, usando o VisualG, mas não fazia ideia de como prosseguir usando a linguagem C Assistindo todos os vídeos dele e aprendendo cada vez mais!
Comment from : Paulo Sena

Now, the unique error that remained was: " :( handles same starting and ending sizesbr expected "Years: 0", not "Years: 1" How can I solve this?
Comment from : Danilo Voz de Trovão

Thank you bro!! You explain this so good!!
Comment from : Daniel Mainardis

well, thank you for helping me, but in the end a realized i have just puts some lettters in the wrong place, but still a very good teacher, recommend to my friends
Comment from : Gabriel de Souza de Oliveira

For people who have never coded before , i feel like this is very complicated for WEEK 0 im so lost
Comment from : Ben

so no need to manually truncate?

Comment from : SNK

Thank you! Very clear explanation and easy to understand :) (I don't feel as dumb as I did before lol) I will be watching your other videos as I do the course Thanks for taking the time to do these videos
Comment from : lyn m

for some reason when i write the same starting size and ending size the number of years is one not zero
Comment from : Youssef Awad

Thank you so much ❤️
Comment from : Xsilverx

I love how he explains his code
Comment from : Structor Modeling

When you explained WHY we switch "years" to "year" because the starting year is 0it finally clicked! Massive W!!! Thank you! Subbed!
Comment from : GOODIES

thank you for this video but why does my code say this br/ $ make populationbrmake: b*/b No rule to make target 'population' Stopbr:(( thank you so much if anyone can help
Comment from : Thiranida Tangjadetanapon

thank you so much bro you helped me a lot
Comment from : Toni Ramzy

Thank you very much! I have a problem, when I correct it with check50, all are ok except when the start and end are the same number for example with 100 it should come out 0 but I get 1, what can I do?
Comment from : Ari Castro

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

Wow! I came to this channel looking for help for the two Mario piramids like 10 months ago 😅 now I'm at week 10 (bc I stopped some months in week 8) and I'm glad you're back!
