C Program to Evaluate the Given Polynomial Equation

 To deduce an error in polynomial equation.....

code : 

#include <stdio.h>

int main() {

    int order, i;

    float x, sum, power;

    printf("Enter the order of the polynomial: ");

    scanf("%d", &order);

    printf("Enter the value of x: ");

    scanf("%f", &x);

    float coefficients[order + 1];

    printf("Enter the coefficients of the polynomial:\n");

    for (i = 0; i <= order; i++) {

        printf("x^%d: ", i);

        scanf("%f", &coefficients[i]);

    }

    sum = coefficients[0];

    power = 1;

    for (i = 1; i <= order; i++) {

        power *= x;

        sum += coefficients[i] * power;

    }

    printf("The polynomial equation is: ");

    // Print the polynomial in a user-friendly format

    for (i = order; i >= 0; i--) {

        if (coefficients[i] != 0) {

            if (coefficients[i] > 0 && i > 0) {

                printf("+ ");

            } else if (coefficients[i] < 0) {

                printf("- ");

                if (coefficients[i] * -1 != 1) {

                    printf("%.2f ", fabs(coefficients[i]));

                }

            } else if (i > 0) {

                printf("+ ");

            }

            if (i > 0) {

                printf("%.2fx^%d ", fabs(coefficients[i]), i);

            } else {

                printf("%.2f", fabs(coefficients[i]));

            }

        }

    }

    printf("\nThe value of the polynomial at x = %.2f is %.2f\n", x, sum);

    return 0;
