## c++ – A program whose receive 10 number from user and calculate the sum of even numbers

Hello I want to use c++for creat a program whose receive 10 number from user, and given the sum of even numbers.

My attempt :

``````#include<iostream >
using namespace std;
int main ()
{
int num, number ;
int sumnum=0;

for(int i=1;i<=10;i++){

cout<<"enter a num" <<i<<endl;
cin>>num;

}

number=num%2;
sumnum +=number ;
if(number ==0){
cout<<sumnum;
}

}
``````

My attempt didn’t work

please I want to develop this attempt, I don’t want to know any other method.

## algorithm – How can I calculate big factorials using Python?

For example, for 25! you would extract 2 and 5, then multiply the 5 by 24 (=120) and hold the 0 (=12). Next, you take what’s left (12) and add it to 24 multiplied by the other digit left from the original number (2) so: (24*2)+12 = 60
Then hold the 0 again and repeat the process until we get the result.

To summarize, for 25!:

24*5=120

24*2+12=60

=> 600

0*23=0

0*23=0

6*23=138

=> 13800

0*22=0

0*22=0

8*22=176

3*22+17=83

1*22+8=30

and so on.

The code has to work for factorials as big as 500!, 1000! and 10000!.

## google sheets – How do I calculate totals of certain words used in a workbook?

I’m trying to find out what products are the most commonly used on r/skincareaddiction. So I want the sheet Totals to count how many times a word was used in the workbook, BUT I only want it to count it once per sheet. So if a sheet says “Origins GinZing Eye Cream” twice in a single sheet I want it count it as once, since that’s the same person saying they use it twice in one day.

## Formula to calculate overhead(space for indirect blocks and internal fragmentation) used?

Im trying to find a formula to determine the over head used in a file system. We are given a 2GB file and have 2KB blocks in a UNIX filesystem. Im trying to find the formula used to determine the space is used by overhead in this example.I couldn’t find a formula anywhere I looked online.

## Google Sheets Sigma notation to calculate series

I have to calculate a series but since the `Sigma` icon represents ALL possible formulas in the UI, it’s very difficult to find a documentation on the actual "mathematical" summation symbol.

Let’s say I want to calculate something like the growth of an hypothetical animal that weighs 200g over 3 years.

My mathematical notation would be the following But I don’t know how to represent that in Google Sheets. What I did find was `SERIESSUM` however the documentation left me with more question than answers, I’m not sure if the "power sum" they mention is what I am looking for.

## sequences and series – If 1 + 2 + 3 + 4 … = – 1/12 calculate (1.001 + 2.001 + 3.001 + 4.001 …) – (1 + 2 + 3 + 4 …) =?

This question makes little sense.

In part 1), the “If” clause “If 1 + 2 + 3 + 4 … = – 1/12” is false. So part 1) is not actually asking anything.

In part 2), I don’t believe the word “supersummation” has a meaning in mathematics, and in any case Z has already been defined so it is unclear how anything could “obtain” Z as anything other than it already is. Which is undefined, since the difference of two divergent series is not defined.

The false claim that 1 + 2 + 3 + 4 … = – 1/12 arises from the initial definition of the Riemann zeta function 𝜁(s) as the infinite series 𝜁(s) = 1/1s + 1/2s + 1/3s + … that converges only for Re(s) > 1. Analytic continuation is then used to define 𝜁(s) for all complex s ≠ 1 as a meromorphic function which happens to satisfy 𝜁(-1) = -1/12. By plugging -1 into the initial series definition of zeta — where the series is not valid — one gets the false claim that 1 + 2 + 3 + 4 … = – 1/12.
