Test Two Q4:

The answer for the question 4 for test two:


 templat <class T>class SQueue : public Queue<T>, public fstream {
             char* _fname;



public: SQueue(const char* fname):Queue(),fstream(fname, ios::binary|ios::in|ios::out) { 

    _fname = new char[strlen(fname) + 1];

     strcpy(_fname, fname);

     open(fname, ios::binary|ios::in);

      seekg((ios::pos_type)0 ,ios::beg);

     T t;
        while (read((char*)&t,sizeof(T))) {

         Queue::Add(t);

}

    close();

}

~SQueue() {

T t;

open(_fname, ios::out|ios::binary );

seekp((ios::pos_type)0 ,ios::beg);while (t=Remove()) {

write((char*)t,sizeof(T));

}

close();

}

};
intmain() {

 
SQueue<int> sq("c:\atieh\test.bin");

}
