BOOKC, this time share about find sum of series c++ code
Find sum of given series in which user enter a number and program calculate series using while loop.
Series example:
if input number = 100
1/1 +1/2 +1/4 +.......+ 1/100

`//this program will calculate sum of following series// 1/1 +1/2 +1/4 +.......+ 1/100.#include<iostream>#include<conio.h>using namespace std;int main(){    float n=1.0;    float d=2.0;    float sum=1.0;    float temp=0.0;    cout<<"Enter a number:";    int number;    cin>>number;    while(d<=number)                    //loop will start from denominator=2 & steps 1,2 &3 continues till d=100.    {      temp=n/d;                     // 1) temp=1/2=0.5      sum=sum+temp;                 // 2) sum=1+0.5=1.5      d=d+2;                        // 3) d=2+2=4      }      cout<<"sum of series is:"<<sum<<endl;      getch();      return 0;}`

Output:

It is recommended to dry run the code on paper and changes the series to understand more.
