Question

What am I doing wrong?

Answer 1

Here's the code:
#include<iostream>
#include<iomanip>
#include<cmath>

using namespace std;

int main()
{
double app1 = 4;
double app2 = 4-4/3+4/5;
double app3 = 4-4/3+4/5-4/7+4/9;
cout << "Pi approximations:" <<endl;
cout << "1st approximation: " << fixed << setprecision(3) << app1 << endl;
cout << "2nd approximation: " << fixed << setprecision(3) << app2 << endl;
cout << "3rd approximation: " << fixed << setprecision(3) << app3 << endl;
system("pause");
return 0;
}
