Question

Name: 3. (15pt) Suppose we are developing a library to deal with polynomials. To represent polynomials, we use single link lists with the following cell structure: type def struct pol 3x +2x 400 int coeffi int degree; coeff degree coeff degree o struct poly next polyT As in the above example, the terms of a polynomial are usually sorted in decreasing order of degrees But what if that is not the case (e.g., if the above polynomial was given as 3x3 400 +2x3), it would be represented as follows Suppose we want it to be sorted. So now you are asked to implement a function void poly sort (polyT p) which sorts the terms of a given polynomial in decreasing order of degrees as follows: use the next page to answer this question.

Explanation / Answer

void sort(polyT *p)
{
   polyT cur;
   polyT *temp = head;
   polyT *temp1;

   while (temp != NULL)
   {
       temp1 = temp->next;
       while (temp1 != NULL)
       {
           if (temp->degree < temp1->degree)
           {
               cur.coeff = temp->coeff;
               cur.degree = temp->degree;
               temp->coeff = temp1->coeff;
               temp->degree = temp1->degree;
               temp1->coeff = cur.coeff;
               temp1->degree = cur.degree;
           }
           else
           {
               temp1 = temp1->next;
           }
       }
       temp = temp->next;
   }

}

---------------------------------------------------

when executed with full program , Output as below

output

Before sorting polynomial
Coefficient = 3 degree =5
Coefficient = -400 degree =0
Coefficient = 2 degree =3
After sorting polynomial
Coefficient = 3 degree =5
Coefficient = 2 degree =3
Coefficient = -400 degree =0
