My program can only evaluate less than 2nd order polynomials but greater than that the evaluation is always wrong due to the term before the constant term is not having any value because of the loop..

example:
the order of polynomial is 3rd
the constants are 1,2,3,4
x=3
1(3)^3+2(3)^2+3(3)^1+4=58
but the program will only print
1(3)^3+2(3)^2+4=49

Code:
```#include <stdio.h>
#include <conio.h>
#include <math.h>
#include <stdlib.h>

main(){
double poly[11];
double polysum;
int n, i, x, y, z;

printf("Enter the order of polynomial: ");
scanf("%d", &n);
y=n;
z=n;
for (i = 0; i < y+1; i++){
printf("Please enter the constant for x raised to the %dth: ", y--);
scanf("%lf", &poly[i]);
}
printf("Please enter the constant for x raised to the 0th: ");
scanf("%lf", &poly[10]);
printf("Enter the value of X: ");
scanf("%d", &x);
for (i = 0; i < n+1; i++){
polysum+=poly[i]*pow(x,n);
n--;
}
polysum=polysum+poly[10];
printf("The evaluated value of the %dth Order Polynomial  %lf\n", z, polysum);
getche();```
