C++ program to find the sum of the series 1/1! + 2/2! + 3/3! + 4/4! +…….+ n/n!
In this tutorial, we will be discussing a program to find the sum of the given series 1/1! + 2/2! + 3/3! + 4/4! +…….+ n/n!.
For this, we will be given with the value of n and our task is to add up every term starting from the first one to find the sum of the given series.
Example
#include <iostream> using namespace std; //calculating the sum of the series double calc_sum(int n) { int i; double sum = 0, fact=1; for (i = 1; i <= n; i++) fact = fact * i; sum += i/fact; return sum; } int main() { int n = 6; double res = calc_sum(n); cout << res << endl; return 0; }
Output
0.00972222
