Chapter 5.2, Problem 8E

(Numerical analysis) a. The following is an approximate conversion formula for converting Fahrenheit to Celsius temperatures:

C e l s i u s   =   ( F a h r e n h e i t     30 )   /   2

Using this formula, and starting with a Fahrenheit temperature of 0 degrees, write a C++ program that determines when the approximate equivalent Celsius temperature differs from the exact equivalent value by more than 4 degrees. (Hint: Use a while loop that terminates when the difference between approximate and exact Celsius equivalents exceeds 4 degrees.)

b. Using the approximate Celsius conversion formula given in Exercise 8a, write a C++ program that produces a table of Fahrenheit temperatures, exact Celsius equivalent temperatures, approximate Celsius equivalent temperatures, and the difference between the exact and approximate equivalent Celsius values. The table should begin at 0 degrees Fahrenheit, use 2-degree Fahrenheit increments, and terminate when the difference between exact and approximate values is more than 4 degrees.

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.
