Hi Friends
Please help me to write a C program to find the 5th (fifth) root of a given number.
Ex:(1) Input : 32
Output : 5th root of 32 is 2
Ex:(1) Input : 243
Output : 5th root of 243 is 3

The definition 0^0=1 is sometimes used to simplify
formulas, but it should be kept in mind that this
equality is a definition and not a fundamental
mathematical truth (Knuth 1992; Knuth 1997, p. 56).

That's quite a weird statement, if you think about it. I know it's not
your statement but Mathworld's, but still.
To my surprise (and to get on-topic), C99 doesn't really say what
pow(0.0, 0.0) should be:
"The pow functions compute x raised to the power y. A domain error
occurs if x is finite and negative and y is finite and not an integer
value. A domain error may occur if x is zero and y is less than or equal
to zero. A range error may occur."
(Knuth 1992; Knuth 1997, p. 56).
Knuth Vol 1, third edition, seems to be giving more info on binomials
than I could ever care to know on page 56, but nothing about exponentials.
Best regards,
Sidney

So I see! F.9.4.4:
"pow(x,±0) returns 1 for any x, even a NaN."
The NaN clause is a surprise, to me at least.

Hello all,
I am writing a script where I need to use the system() function to call

Hi,
I'm trying to work on a recursive function that will give me root

What i mean by root value is, if given 13, the answer is 1+3 = 4. If
given 65, the answer is 2, i.e, 6+5=11, and 1+1=2. The final answer is
always less than 10.

My thinking was:

(b) attach event handlers which, onmousedown, specify the slider/nub is
moveable, and onmouseup, specify it's not
(c) attach an event handler to the contaning div which,...

Hello, I'm using tiny MCE plugin on my oscommerce and it is inserting my website URL when I use insert image function in the emails.
The goal is: Make it send the email with the URL http://mghospedagem.com/images/controlpanel.jpg
instead of
http://mghospedagem.comhttp://mghospedagem.com/images/controlpanel.jpg
As u see, there's the website URL before the image URL.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
