C++ program to find the sum of the series 1 + 1/2^2 + 1/3^3 + …..+ 1/n^n
In this tutorial, we will be discussing a program to find the sum of the given series 1 + 1/2^2 + 1/3^3 + …..+ 1/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>
#include <math.h>
using namespace std;
//calculating the sum of the series
double calc_sum(int n) {
int i;
double sum = 0.0, ser;
for (i = 1; i <= n; i++)
ser = 1/ pow(i, i);
sum += ser;
return sum;
}
int main() {
int n = 5;
double res = calc_sum(n);
cout << res << endl;
return 0;
}Output
0.00032
