C++Server Side ProgrammingProgramming

In this tutorial, we will be discussing a program to find sum of series 1 + ½ + ? + ¼ + … +1/n

For this we will be provided with the value of n. Our task is to calculate the sum of the series upto the given value and print it out.

## Example

Live Demo

#include <iostream>
using namespace std;
//returning the sum of given series
class sum_series {
public : double sum(int n) {
double i, s = 0.0;
for (i = 1; i <= n; i++)
s = s + 1/i;
return s;
}
};
int main() {
sum_series g;
int n = 5;
cout << "Sum is " << g.sum(n);
return 0;
}

## Output

Sum is 2.28333
