i have a problem printing out my linked list. My program asks the user to enter many different coefficients and degrees and makes it a polynomial and using mergesort it sorts it and then prints it, now i want to combine like terms and i have a problem doing so.

thats part of my function that i don't know what is wrong with it:

  Term* p;
  p=poly;
  if (p==0)
    cout<<"---empty list---";
  while(p !=0)
    if (p->coef==(p->next)->coef){
      cout<<(p->deg)+((p->next)->deg)<<"x^"<<(p->coef)<<endl;
      p=p->next;}
    if (p->coef !=(p->next)->coef){
      cout<<p->deg<<"x"<<p->coef<<"+";
      p=p->next;}
  cout<<endl;
}

and thats my struct:

struct Term {
    int deg;
    float coef;
    Term *next;
};
typedef Term* Poly;
