C# How to Use Recursion

[@VenkatNagella]

Thank you! the way you explained is a piece of cake for anybody as you said starting of the video. Thanks for your time and effort. Now i understood the recursion concept.

[@alokin0073]

God bless you mate I have a exam in a couple of days and you helped me a lot :)

[@RenaissanceCoders]

Hi outtoplay, I am unable to reply directly to your comment for some reason, but thank you! And yes you should be able to use MonoDevelop to follow along.

if(powerOf ==0) return 1; It'll work.

[@makanathegreat3234]

That's what I was thinking too. It's less complicated just to fix your condition statement.

[@Otto-the-Autopilot]

It will also make your call stack become one step deeper in the end. So even though it will in this case not make any noticeable difference at all, I'd still already exit when num == 1. Doesn't make the code any less understandable yet is better performance wise.

[@jlearner4605]

You have explained it simple and precise. Thank you.

[@solvedplus858]

many thanks for your nice tutorial

[@dastoto0166]

oh my god I finally understand recursion!! 🥺

[@Darival92]

hi, great video, i have a question a little off topic, how did you set the dots in every line on VS? it lookes more organized

[@Steven_Random_Suffix]

It's an option called "View White Space", Go to "Edit" > "Advanced" > "View White Space" While you are there, you might want to consider to enable "Word Wrap" as well, might help in some cases (or be annoying, also possible)

[@makanathegreat3234]

You won't need to return num. All you have to do is fix your conditions: if(powerOf

[@mauriromero6]

Thxs, this helped me a lot

[@stephenpino2936]

Good for basic concepts thanks!

[@mohamedarafa7599]

how the program know that i do program factorial and the name of method is any sords which i write to know what i do only

[@alaazarnaji6602]

that was such a useful tutorial . just have one Question I wanna prompt the user to give me the value using ReadLine but how ! when I give it Converts.toint32(Consol.readLine()); it says it's inaccessible due to its protection.

[@RenaissanceCoders]

The error "inaccessible due to its protection" basically means that we cannot access the variable that is bring referenced, so you need to change our variable to be public instead of private and that should fix the issue.

[@alaazarnaji6602]

it worked . thank you Renaissance coders ^ ^

[@RenaissanceCoders]

Hey, you are certainly welcome!! :)

[@TheExamian]

I'm just starting to learn coding and your video really helped, thank you!! What I don't quite get is, what "bool running = true, while(running {};" does in your main function. If someone has an explanation for me I would be really happy :)

[@Otto-the-Autopilot]

It forces the application to stay within the Main method by looping forever, preventing it to close itself again right after printing the answer (user has to kill it). It works, but is also stressing the system since the application is infinite looping. Most developers therefore use "Console.ReadLine();" at the end of the Main method instead, to prevent the app from automatically closing itself. Not very important for simple demo purposes like these of course, though I do think you should never waste any resources if it can be easily prevented.

[@muxammad2777]

I think its like using this Console.ReadKey(); so that the program running until he closes it, that is what im thinking im not sure,

[@outtoplay]

Terrific work! Quick question... Is it possible to do your C# tutorials on a Mac? I see that mose C# tuts use Visual Studio, But my mac is my main box. Can I do these lessons in MonoDevelop? Thanks.

[@beastmasterbg]

thank you

[@Flowerpot2905]

This is confusing for me... I'm not understanding where the factorials are being added together? I would expect there to be a += somewhere in the formula. But maths is not my strong suit. I suppose it is because the variable value keeps updating itself, and then running again, like a loop. My brain is struggling with this! 🙂

[@ayeletyam2553]

I study software engineering in 11th grade and we are always taught you cant do write methods inside the main only call them.

[@ayeletyam2553]

they say we should write them above the main

[@RenaissanceCoders]

Ayelet Yam That is only necessary for lower level compilers like C++ compilers where source files are parsed from the top down.

[@PandaTheGFX]

My guess is because most people will make a transition to another language that may be influenced by this, so they teach you that way so you get used "just in case"

[@hadarnada8701]

pretty helpful, helped me to undersrtand the basic concept

[@TheVeveus]

thanks

[@HelloQro]

power of zero wouldn't work tho

[@TheAdun]

sorry but this video does not explain the concept at all.
