class PrintMarks {
    private:
        std::vector<int>* marks;
        void printMarks() {
            std::cout << "Printing marks" << std::endl;
            for ( int i = 0; i < marks->size(); i++ ) {
                std::cout << marks->at(i) <<  " ";
            }
        }
    public:
        PrintMarks() {
            this->marks = new std::vector<int>();
        }
        ~PrintMarks() {
            delete marks;
        }
        void inputMarks() {
            std::cout << "Please input marks.-1 would mean that you're done entering the sequence." <<std::endl;
            for ( ; ;) {
                int input = 0;
                std::cin >>input;
                if ( input == -1 ) {
                    break;
                }
                marks->push_back(input);
            }
            this->printMarks();
        }
};
int main() {
    PrintMarks *tryIt = new  PrintMarks();
    tryIt->inputMarks();
    return 0;
}
