Explanation:

You've already answered the question you posted.

The programming language is not stated. however, the syntax is close to java & c++ and there's a need for alteration on the program to make it run perfectly.

If it is Java,

change

public double fractionSum(int n) {

to

public static double fractionSum(int n) {

If it is C++, change

public double fractionSum(int n) {

to

double fractionSum(int n) {

To call the program from the main method, write:

Java:

System.out.print(fractionSum(n));

C++:

cout<<fractionSum(n);
