[solved] – Question 81587

2. The value of p can be approximated by using the following series:
–
¼ 4 1 1
3 þ
1
5 1
7 þþ
1
2n 1 þ
1
2n þ 1
:
The following program uses this series to find the approximate value of p. However,
the statements are in the incorrect order, and there is also a bug in this program.
Rearrange the statements and also find and remove the bug so that this program can
be used to approximate p.#include <iostream>
#include <iomanip>
using namespace std;
int main()
{
double pi = 0;
long i;
long n;
cin >> n;
cout << “Enter the value of n: “;
cout << endl;
if (i % 2 == 0)
pi = pi + (1 / (2 * i + 1));
else
pi = pi – (1 / (2 * i + 1));
for (i = 0; i < n; i++)
{
pi = 0;
pi = 4 * pi;
}
cout << endl << “pi = ” << pi << endl;
return 0;
