Calculate for a given value X of the type float the numerical value of a polynomial of degree n: \(P(X) = A_nX^n + A_{n-1}X^{n-1}+ \cdots + A_1X + A_0\)

The values of n, coefficients \(A_n, \cdots , A_0\) and X will be entered on the keyboard.

Use the Horner schema that avoids exponentiation operations when calculating: \(P(X) = (( ( (A_n \times X + A_{n-1}) \times X + A_{n-2} ) \cdots  ) \times X + A_0 \)

#include <stdio.h>
#include <conio.h>

void main()
{
	int N;     /* degree */
 	float X;   /* argument          */
 	float A;   /* coefficients */
 	float P;   /* P */

 	printf("Enter the degree n ofthe polynomial : ");
 	scanf("%d", &N);
 	printf("Enter the value X of the argument : ");
 	scanf("%f", &X);

 	for(P=0.0 ; N>=0 ; N--)
   	{
    	 	printf("Enter coefficient A%d : ", N);
    		scanf("%f", &A);
    		P = P*X + A;
   	}
 
 	printf("P(%.2f)=%.2f\n", X, P);

	getch();
