Under the display() and evaluate() I get an error code saying that the explicit type is missing('int' assumed). I'm stuck on this part and I'm wondering how I could fix this, would appreciate any assistance.
#pragma warning
#include <iostream>
using namespace std;
class poly {
    int degree;
    int* coeff;
public:
    poly(int);
    poly(poly&);
    poly();
    ~poly();
    display();
    evaluate(int);
    poly operator+(poly&);
    poly operator*(poly&);
};
