Movie Data Program Plan: Include the required header files. Declare the structure named “MovieData”. Declare the variables. Declare a function “disp_Movie”. Inside the main() function. Create two variables “movie_1” and “movie_2” for “MovieData”. Assign the value of movie title, director, year released and movie length information to movie 1 and movie 2. Call the function disp_movie() to display the movie1 and movie 2. Define the function “disp_movie()”. In the function, display the move title, director of movie, year released and running time of movie in minutes.

Question

If a UDP datagram is sent from host A, port P to host B, port Q, but at host B there is no process listening to port Q, then B is to send back an ICMP Port Unreachable message to A. Like all ICMP messages, this is addressed to A as a whole, not to port P on A. (a) Give an example of when an application might want to receive such ICMP messages. (b) Find out what an application has to do, on the operating system of your choice, to receive such messages. (c) Why might it not be a good idea to send such messages directly back to the originating port P on A?

Discuss how business intelligence and data visualization work together to help decision-makers and data users. Provide 2 specific use cases.

This week we will be building a regression model conceptually for our discussion assignment. Consider your current workplace (or previous/future workplace if not currently working) and answer the following set of questions. Expand where needed to help others understand your thinking: What is the most important factor (variable) that needs to be predicted accurately at work? Why? Justify its selection as your dependent variable.
