Programming Exercise 5-2 Instructions main.cpp + 1 #include 2 #include Instructions 3 4 using namespace std; The value of i can be approximated by using the 5 following series: 6 int main( ) 7 { 8 double pi = 0; It = 4 + + + 9 long i; 2n 2n + 1 10 long n; 11 The program in main.cpp uses this series to find the 12 cin > > n; approximate value of 17. However, the statements are in 13 cout
