The nth digit

[aidam]

Can anyone help me to create a function that I put a number, the position of the digit, and the function returns me the digit that is in this position (from left to right)
ex:(3658,0) = 3 The digit in position 0 is 3

Hi aidam,
Here it is... just go check here https://www.punksheep.com/partage/C++/nthDigit.zip
==> just delete the #include "stdafx.h" :D I'm on Vindowz hehehe

By the way, is there a pastebin here ?

[aidam]

I couldn't open.
i dont know what is happening

oouhhhh aidam,
You're right ! sorry... I don't know what the pity my ftp client did with the file :(... and by now I found how to paste a source code so here it is :

char nthDigitFromLeftToRightOf(int number, int const posDigit)
{
	auto numberString = std::to_string(number);
	auto const stringLength = numberString.length();
	return (stringLength <= posDigit) ? '0' : numberString[posDigit];
}

Sorry again man... I'm on my way to check what's happening to my website :(
Thank you ;)

You can find the full source code with the function for both ways here https://www.punksheep.com/partage/C++/nthDigit.zip

See ya ;)

P.S. : here the full code

thank u very much guy !!

thanks to you too aidam.
I didn't figure out my "transfert" problem... it's a problem with encoding characters !!! wow... 2018 and still some transfer problem even with utf-8 files >_<
So now, I put the zip version, it's a lot better and yes, a little bit smaller too :oP~

Good journey to you on your path of the C++ \o/
