Answer 1

#include <iostream>#include <vector>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;}
