Write the Printpoly, evaluate, and terms functions.

The printpoly function prints the whole polynomial.

The evaluate function takes the given value for "x" and solves the polynomial.

The terms function counts the number of terms in the polynomial.

Create a directory called lab9 on your machine using mkdir lab9 and complete the program below. You must write the three functions shown in red (printPoly, evaluate, terms). The code below can be downloaded from the course Blackboard site. lab9.c shown #include # include #include typedef struct poly double coeff int degree; struct poly *next; Poly void printPoly (Poly*) double evaluate (Poly double) int terms (Poly *) int main (void) Poly *myPoly = NULL ; printf ("Enter the coefficient and degree of a term to add to the polynomial "); double ci int d scanf ("%If %d", &c , &d); while ( ! ( fabs (c-0.0) coeffc; newNode->degreed newNode->next = myPoly; myPoly = newNode; printf ("Enter a coefficient and degree (or 0 0 to stop adding terms)"); scanf ( " % 1 f %d", &c, &d); printf (" ") printf ("The polynomial is : "); printPoly (myPoly) printf (" ") printf ("The polynomial has %d terms ", terms (myPoly) ); printf ("Polynomial evaluation - enter a value for x: "); double x; scanf ("%lf", &x) ; printf("\tThe value of the polynomial at x=%lf is %lf ", x, evaluate (myPoly, x) ); return 0 A sample execution of th is program is shown below Enter the coefficient and degree of a term to add to the polynomial:0.5 0 Enter a coefficient and degree (or 0 0 to stop adding terms)1.5 1 Enter a coefficient and degree (or 0 0 to stop adding terms) 2.5 2 Enter a coefficient and degree (or 0 0 to stop adding terms) 3.5 3 Enter a coefficient and degree (or 0 0 to stop adding terms)0 0 The polynomial is: 3.500000 x*3 2.500000 2+1.500000 x*1 + 0.500000 x*0 The polynomial has 4 terms Polynomial evaluation - enter a value for x : 5 The value of the polynomial at x=5.000000 is 508.000000
