Manipulations of polynomials with lists
0
Here are my functions and structures, what does not work is the
derivative and value at the precise point void Derivee,
float Valeur. I work with lists, of course.
get_at(polyliste* p, int index ,float* coeff,int* deg)
typedef struct node* Node;
typedef struct node
{
float coeff;
int degree;
Node next;
} node;
typedef struct
{
Node head;
} polyliste;
polyliste create()
{
polyliste p;
p.head = NULL;
return p;
}
float Valeur(polyliste p, float x)
{
float s = 0, coeff;
int i = 0, degree;
while (get_at(&p, i, &coeff, °ree) == 0)
{
s = s + (coeff * power(x, degree));
i++;
}
printf("nLe resultat est : %f", s);
return s;
}
void Derivee(polyliste *p, polyliste *s)
{
int i = 0, degree;
float coeff;
*s = create();
while (get_at(&p, i, &coeff, °ree) == 0)
{
if ((coeff != 0) && (degree != 0))
{
coeff *= degree;
degree--;
add_first(s, degree, coeff);
}
i++;
}
}

Welcome on stackoverflow, please take the tour and read this: How to Ask. Then you need to edit your question and provide a Minimal, Complete, and Verifiable example and an example of input and expected output.

my program doesnt work , example of input 3X^2+2X+1 it would give me 6X+2
– Jihane.j

Jihane.j, What is wrong with6X+2? What is the goal?
