Why isn't my code working?

How do I fix this?

It is C.

#include #include

float horner(float p[], int n, float x) { int r = 0, i; for (i = 0; i

int main(int argc, char* args[]) { //get polynomial efficients from command line arguments if (argc <= 1) { printf("Need more than one arguments, e.g.: 1 2 3 4 "); return 0; }

int n = argc-1;

// declare float array data structure for coefficients // read command line arguments convert them to floating numbers atof(args[i+1]);

// repetitive polynomial evaluation for user input of x value float x = 0.0; do { //get x value from keyboard do { printf("Please enter x value (Ctrl+C or 999 to quit): "); if (scanf("%f", &x) != 1) { printf("Invalid input "); } else { break; } // flush the input buffer while(getchar() !=' '); } while (1); printf("Please enter x value (Ctrl+C or 999 to quit):"); int num = 0; scanf("%d", &num); int h = 999; while (num != h){ printf("1.0*%f^3 + 2.0*%f^2 + 3.0*%f^1 + 4.0*%f^0 = %d ", x , x, x, x, num); printf("Please enter x value (Ctrl+C or 999 to quit):"); scanf("%d", &num); }

// write your code // escape when input 999 // print the polynomial expression // use x^n to denote x raised to the n-th power // use %.1f format for floating number // get polynomial's value by calling horner(p, n, x)

} while (1);

return 0; }
