Chapter 7, Problem 7.35MAD

Making a Difference
7.35 (Polling) The Internet and the web enable people to network, join a cause, and so on. The presidential candidates use the Internet to get out their messages and raise money. In this exercise, you’ll write a polling program that allows users to rate five social-consciousness issues from 1 to 10 (most important). Pick five causes (e.g., political issues, global environmental issues). Use a one-dimensional string array topics to store the causes. To summarize the survey responses, use a 5-row, 10-column two-dimensional array responses (of type int), each row corresponding to an element in the topics array. When the program runs, it should ask the user to rate each issue. Have your friends and family respond to the survey. Then have the program display a summary of the results, including:
a) A tabular report with the five topics down the left side and the 10 ratings across the top. listing in each column the number of ratings received for each topic.
b) To the right of each row, show the average of the ratings for that issue.
c) Which issue received the highest point total? Display both the issue and the point total.
d) Which issue received the lowest point total? Display both the issue and the point total.

Dijkstra's Algorithm (part 1).  Consider the network shown below, and Dijkstra’s link-state algorithm. Here, we are interested in computing the least cost path from node E (note: the start node here is E) to all other nodes using Dijkstra's algorithm. Using the algorithm statement used in the textbook and its visual representation, complete the "Step 0" row in the table below showing the link state algorithm’s execution by matching the table entries (i), (ii), (iii), and (iv) with their values.  Write down your final [correct] answer, as you‘ll need it for the next question.
