I declare the two class Momomial, Polynomial, the Polynomial has a pointer to an array Momomial, then I want to overload operators "+", make two Polynomial class together
Now I can almost sure the problem in the definition of the overloaded function "+"

 Polynomial operator + (Polynomial & amp; A, Polynomial & amp; B) {
Momomial * q=new Momomial [a.n um_m + b.n um_m]; 
for(int i=0; IIf (iQ [I] a=Amy polumbo [I] a;

For (int j1=0; J1 & lt; B.n um_m; {j1 + +) 
If (q [i1] n==q [a.n um_m + j1]. N) {
Q [i1]. A +=q [a.n um_m + j1]. A; 
Q [j1 + a.n um_m] a=0; 
count++; 
break; } 
}
