Simpson's 3/8th rule to find Integration of Difference Table

#include<iostream>
using namespace std;
int main()
{
    int i,n;
    float x[10],y[10],h,sum;

    cout<<"Enter no of values in table: ";
    cin>>n;
    cout<<"Enter X & corresponding Y:\n";
    for(i=0;i<n;i++)
        cin>>x[i]>>y[i];

Simpson's 3/8th Rule to find Integration of Function

#include<iostream>
#include<math.h>

using namespace std;
float f(float x)
{
    return 1/(1+x*x); //Function f(x)
}
int main()
{
    int i,n;
    float x0,xn,h,sum;
    cout<<"Enter no of Intervals: ";
