Answer 1

Answer:

// C++ program to find sum of series

// 1 + x/1 + x^2/2 + x^3/3 + ....+ x^n/n

#include <math.h>

#include <iostream>

#include <boost/format.hpp>

class gfg

{

public :

double sum(int x, int n)

{

double i, total = 1.0;

for (i = 1; i <= n; i++)

total = total +

(pow(x, i) / i);

return total;

}

};

// Driver code

int main()

{

gfg g;

int x = 2;

int n = 5;

//std::cout<<g.sum(x,n);

std::cout << boost::format("%.2f") % g.sum(x,n);

return 0;

}
