Explanation of Solution

    double *length;

    double *width;

    //set the output format

    cout << fixed << showpoint << setprecision(2);

    //allocate memory to be referred to by length

    length = new double;

    //the statement is incorrect as length is pointer

    //variable and not a double variable

    ///length = 6.5;

    //so the correct code is

    *length = 6.5;

    //statement is incorrect as & is an address of operator

    /// &width = 3.0;

    //so the correct set of statements are shown below

    //where first memory is allocated and then the value

    //is assigned

    width = new double;

    *width = 3...
