Thread: linked lists of a polynomial

Hi every one, I'm very new in c++ programming, and I'm encounting some difficulties with my program. It's supposed to create a polynomial with a linked list. It keeps giving me errors and I don't know what to do anymore. The polynomial is created with a single nested statement in the constructor. But it doesn't seem to work. Please help me.


class Term
{
public:
Term (double coefficient, int exponent=0, Term *next=NULL);
double evaluate (double x);
void print();
private:
double coefficient;
int exponent;
Term *next;
};

Term::Term(double coefficient, int exponent = 0, Term *next = NULL)
{
Term *pt = new Term(1,10, new Term(-3,4,new Term (17)));
}

double Term::evaluate (double x);
{
if (Term *pt != NULL)
{
while(pt->next != NULL)
{
int expo = ptr->exponent;
double accum+ = ptr->coefficient * pow(x, expo);
ptr=ptr->next;
}
ptr->next = NULL;
}
return accum;
}

int main()
{
Term test;
double result = test.evaluate (2);
cout << "and the answer is: " << result << endl;
return 0;
}
