A simple implementation of C language to find the method of N-order-de polynomial _c language

The example of this article is about the simple realization of C language to find the N-order polynomial method. Share to everyone for your reference, specific as follows:

#include <stdio.h>
float p (float x,int N)
{
float p_n;
 if (0==n)
 {p_n=1;}
 else if (1==n)
 {
 p_n=x
 }
 else
 {
 p_n= (2*n-1) *x-p (x,n-1)-(n-1) *p (x,n-2))/n;
 return p_n;
}
Main ()
{
 int n;
 printf ("Input n:");
 scanf ("%d", &n);
 float x;
 printf ("Input x:");
 scanf ("%f", &x);
 printf ("%f", p (x,n));
}

I hope this article will help you with the C language program design.
