Square root and power functions (C++ programming tutorial)

[@Engineer4Free]

I use Xcode 3. If you are using the same program you can select "view > message bubbles > all issues" from the top menu and they will be displayed. If you are using a different program you should look through its view menu (or something similar) and try to find something about displaying messages.

[@toxicwall6593]

Thx a lot this was way easier than the other tutorials ive seen

[@Engineer4Free]

Thanks for letting me know 🙂

[@syedarimshakazmi5622]

Thanks a lot ur vid literally helped me

[@Engineer4Free]

Glad to hear it! There is more at engineer4free.com/cplusplus =)

[@moniramohazabin7895]

Thank for your tutorial

[@Engineer4Free]

Thanks for watching =)

[@Engineer4Free]

glad to hear it!

[@mrryanbond007]

thx very helpful, never thought that it only required a new header

[@Engineer4Free]

You're welcome!! =)

[@veejj6843]

But what if that number that you are square rooting is a variable, regardless if its an integer or not, and you want to continue to use the square rooted number with more addition before showing it on screen? I am trying to make a C++ program for finding the Surface Area of a Cone and I have to continue to use the number after it is square rooted. Any help?

[@MrComonroots99]

How do you get the options to pop up after you double click the cmd (pow,sqrt, etc) with the open brackets "double"? I dont get open brackets when I type pow or sqrt.

[@guitarttimman]

Can you put i++ for square?

[@murtazaiqbal9444]

Thank you man it erally helped me in my work

[@Engineer4Free]

+Murtaza Iqbal Always happy to hear when people are finding my videos helpful! Feel free to check out all the C++ tutorials I've made so far here: www.engineer4free.com/cplusplus :)

[@0xS7]

Can someone tell me what program he's using ?

[@Engineer4Free]

RUclips wont let me write proper code in the comments, so here is what you can write (minus the semicolons)
double x
cout

[@barewr828]

What editor are you using?

[@Engineer4Free]

Xcode. You can find all the hardware and software that I use at engineer4free.com/tools

[@jannahmae4194]

what is the difference between math.h and cmath? First year computer science student here.

[@Engineer4Free]

Mmmm, here's a good response to that question from StackOverflow: stackoverflow.com/a/15656459

[@austinedeclan10]

I had no idea I had to include cmath. That's what was missing for me. First year computer science student here.

[@Engineer4Free]

Glad I can help! I remember learning C++ in my first year and the stupidest/tiniest things that I just didn't know to look for would hold me up for hours. If you haven't already, make sure you check out engineer4free.com/cplusplus for the rest of the videos!

[@austinedeclan10]

Engineer4Free thanks a lot man.

[@potato6151]

What text editor are you using? I'm just using the C++ software because I can't seem to run C++ on Brackets

[@Engineer4Free]

It's an older version of Xcode. Here's a good list of alternatives to it too: alternativeto.net/software/xcode/

[@melissasumer]

(X^3/ sqrt x ^2 ) x+2 there was a question like this not exactly the same but how we can do it?

[@alexranos4212]

many thanks u helped me a lot

[@MrComonroots99]

Great, thanks for the info

[@icebergmike27]

what if the input for square root is a negative number? I keep getting nan

[@victorFT10000]

to do the square of a negative number you need to do for ex: square of -25 ou need to separete square of -1 x square of 25 now make the square of 25 and now is square of -1 x 5 they discovered that the square of -1 is i, i is a imaginary number so the answer to the square of -25 is 5i

[@bijansanchez3804]

what if the base is negative and the power is 0.5???

[@the_jingo]

Square root mean power is 2

[@sonicm1997]

thank you very much

[@DarkNight-zc7se]

How to do the cube root????

[@Engineer4Free]

You could code your own function, similar to this one: www.engineer4free.com/4/how-to-build-your-own-power-function-from-scratch

[@DarkNight-zc7se]

@@Engineer4Free Thanks

[@veritasthepotato]

what IDE do you recommend for C++ coding on a mac? I am using Xcode but tbh it sucks :/

[@Engineer4Free]

Here's a pretty good list of alternatives to Xcode. You can filter by platform too: alternativeto.net/software/xcode/

[@BONJABONJA]

I have got a problem, when I try to calculate a square root, if the result contains decimals, It shows me the closest number, and not the result with decimals

[@Engineer4Free]

BonjaVUGM That is very strange. See how it's prompting me to enter a double? It also returns a double. I just tried mine out, if I cout

[@BONJABONJA]

Engineer4Free yes I'm using #include and writting the exact same thing you are writting :/

[@rayzecor]

BonjaVUGM Maybe you are using different engines.

[@startup_cult]

+BonjaVUGM declare the variable in float

[@serifsamate]

+BonjaVUGM might be you need to specify your precision. Try this in your program, right before you cout line:
cout.setf(ios::fixed);cout.setf(ios::showpoint);cout.precision(4);

[@whatislyf]

Thanks alot man, that helped alot :)

Hello mine is not doing square root for numbers which are declared in variables
