Question

In the same file, complete the following exercises in the author’s pseudocode as presented in the
text book and material on Blackboard in this chapter, and following all requirements for good
program design that were shown in Chapter 2 and all examples since then.

At the Summer Olympic Games every four years, for historical reasons, athletes represent
National Olympic Committees (NOCs) rather than strictly countries. For the sake of convenience
in our program, let us refer to them simply as “nations”. As of the 2016 Rio Olympics, then,
there were 206 nations eligible to participate in the Olympics. Write a program that could be
used to represent the medal table for the next Olympics that will be held in Tokyo in 2020. Since
we do not know how many nations will actually participate, our program will have to plan on
there being a maximum of 225 nations (in case some more NOCs are recognized before the 2020
Olympics), but must adapt to fewer nations actually being present. So, write a program that

1. Allows a user to enter
a. The names of the nations that are participating
b. The number of gold medals that nation has won
c. The number of silver medals it has won
d. The number of bronze medals it has won
e. “ZZZ” as the nation’s name to indicate that they have finished entering input

2. Outputs a list of sentences that describe each nation’s performance, e.g., for the 2016
Olympics, to describe the performance of the United States, this program would have
output “United States won 46 gold, 37 silver, and 38 bronze
medals, for a total of 121 medals” . Below this list, the program must
output the total number of gold medals awarded, silver medals awarded and bronze
medals awarded, and total of all medals awarded.

3. Scans for and outputs
a. The names of the nations with the most and least gold medals, along with their
gold medal counts, e.g., “United States won the most gold
medals: 46”
b. Similarly, the names of the nations with the most and least silver and bronze
medals respectively

4. Allows the user to enter the name of a nation that they want to search for, and if it finds
that nation, outputs a sentence in the format shown in #2 above.

All of the above must be done by applying the concepts and algorithms shown in Chapter 6, both
in the text book and in the material provided on Blackboard, and building on what we have
learned in all the chapters before this one.

The only data that this program stores is the names of the nations, and the matching counts of
gold, silver and bronze medals. All calculations and scanning for highest and lowest, etc., must
be done by the program after the user has entered the sentinel to indicate the end of their input.
All output sentences described above must be generated when they are required.

Book this is from is "Programming Logic and Design 8th Edition" by: Joyce Farrell. Must be written in pseudocode that resembles that in the book.

this is what I have so far. It probably isn't right, but it will at least give you some structure to follow. Any help is appreciated.

Answer 1

The logic of the program is as follows:

Start

   Declarations

    string EXIT = ZZZ

    NATION_CAPACITY = 225

    string NATION_NAME[NATION_CAPACITY]

    num g #gold

    num s #silver

    num b #bronze

    num totalMedals

    num count

    num nextNation

    num mostGold

    num leastGold

    num mostSilver

    num leastSilver

    num mostBronze

    num leastBronze

   output "Welcome to our Medal Tracker Program."

   output "This program will allow the user to enter the name of nations and enter the number of gold, silver, and bronze medals that nation has won."

   output "Please enter the name of the nation (type ", ZZZ, " to stop): "

   input nextNation
