        int result = -1, i = 1;

        std::cout<<"Enter Original String:";

        getline(std::cin, org);

        std::cout<<"Enter Pattern String:";

        getline(std::cin, dup);

        do

        {

            result = org.find(dup, result + 1);

            if (result != -1)

                std::cout<<"\nInstance:"<<i<<"\tPosition:"<<result<<"\t";

            i++;

        } while (result >= 0);
