This project should be a .NET Core Console App. Name your project MyDirectoryApp. Make sure you make use of the using directive for File IO. Use the DirectoryInfo type to create a new directory (create it wherever you can). Once created, display on the console the Name of the directory, the CreationTime of the directory, and the Root of the directory.

Consider the following declarations (1, 2, 3, 5, 7)class bagtype{public: void set(string, double, double, double, double); void print() const; string getstyle() const; double getprice() const; void get(double, double, double, double); bagtype(); bagtype(string, double, double, double, double); private: string style: double l; double w; double h; double price; }; a.) write the definition of the number function set so that private members are set according to the parametersb.) write the definition of the member function print that prints the values of the data membersc.) write the definition of the default constructor of the class bagtype so that the private member variables are initialized to "", 0.0, 0.0, 0.0, 0.0, respectively d.) write a c++ statement that prints the value of the object newbag.e.) write a c++ statement that declares the object tempbag of type bagtype, and initialize the member variables of tempbag to "backpack", 15, 8, 20 and 49.99, respectively

Least square fit to polynomial write a function leastsquarefit3pol that solves a linear system of equations to find a least squares fit of a third order polynomial to an experimental data set given as two row arrays. the function leastsquarefit3pol must explicitly solve a set of linear equations and cannot use polyfit. there should be no restriction on the size of the problem that can be solved.

Ingrid started speaking about her slide presentation. when she clicked to th"third slide, which had just a picture of an elephant, she forgot what she wassupposed to talk about. what could ingrid do to avoid this situation in thefuture? oa. print handouts for her audience.ob. add presenter's notes to each slide.oc. add a video to each slide.od. save her slide presentation to a flash drive
