    //declare required variables

    int i;

    bool b;

    //prompt the user to enter the number

    std::cout<<"Enter the number:";

    //scan for the values

    std::cin>>i;

    //call the method isTwoPower()

    b=isTwoPower(i);

    if(b)

    {

        //prompt the user to enter two numbers

        std::cout<<i<<"is power of 2";

    }

    Else

    {

        //prompt the user to enter two numbers
