    Why is there an exception?

    Here is the code,


    bool isRotational(char* s1, char* s2)
    {
    int len = strlen(s1);
    char* s = new char[2 * len + 1];
    char* p = s1;
    char* q = s;

    Re: A question regarding protected member

    But D will inherit the member function foo too. How come we can't call foo on D as an assignment operator is called on D? Thanks.
