    Returning values by reference.

    I am having some problems with an error I do not understand it looks to me the exact same as in the book. Here is the code and the given error.

    Code:
    Code:
    #include <iostream>
    
    using namespace std;
    enum ERR_CODE {SUCCESS, ERROR};
    ERR_CODE Factor(int, int&, int&); // Function prototype
    
    int main()
    {
        int number, squared, cubed;
        ERR_CODE result;
    
        cout << "Enter a number (0-20): " ;
        cin >> number;
    
        result = Factor(number, squared, cubed);
    
        if(result == SUCCESS)
        {
            cout << "Nunber:\t\t" << number << endl;
            cout << "Squared:\t\t" << squared << endl;
            cout << "Cubed:\t\t" << cubed << endl;
        }
        else
        {
            cout << "Error encountered!!" << endl;
        }
    
        return 0;
    }
    
    ERR_CODE Factor(int n, int rSquared, int rCubed)
    {
        if (n > 20)
        {
            return ERROR; // Simple error code
        }
        else
        {
            rSquared = n*n;
            rCubed = n*n*n;
            return SUCCESS;
        }
    }
    Error:
    Line:15 Undefined reference to 'Factor(int, int&, int&)'

    Code:
    ERR_CODE Factor(int, int&, int&); // Function prototype
    
    ...
    
    ERR_CODE Factor(int n, int rSquared, int rCubed)
    The prototype indicates & but the function definition does not.
