Calculate f(4)using Newton`s interpolating polynomials of order 1 through 4. Choose your base points to attain good accuracy. What do your results indicate regarding the order of the polynomial used to generate the data in the table?

#include
using namespace std;
double x[10];
double y[10];
double yint[10];
double fdd[10][10];
double ea[10];
double answer;
int value;
void read_data(double x[] , double y[], int& value)
{int i , j;
double xdata;
cout << "Input Xi n";
for(i = 0 ; i < value ; i++)
{cout << " x"<< i <<": ";
cin >> xdata;
x[i] = xdata;
}
double ydata;
cout << "Input Yi n";
for(j = 0 ; j < value ; j++)
{cout << " y" << j << ": ";
cin >> ydata;
y[j]=ydata;
}
}
