Scenario 1: (LO1, LO2, LO3)
The Ocean Race 2021–22 route is announced. Yachts are ready to sail and will visit 10 international
cities, including the start port and the Grand Finale finish in Genoa, Italy. In ocean navigation,
degrees and minutes (for latitude and longitude) are used to measure locations along with the
direction. Degrees of latitude are either north (N) or south (S) measured from 0 to 180 degrees and
degrees longitude are either east (E) or west (W) measured from 0 to 90.
Example: 38°56’N, 71°0’W is 38 degrees 56 minutes North and 71 degrees 0 minutes West.
Task:
1. Your task is to create a class Yacht that includes the yacht’s number and location (LO3).
a) For Yacht’s Number : You have to number each yacht object as it is created using a
constructor. To do this, you will have a data member that holds a serial number for
each object created from the class. Then you will need another data member that
records a count of how many objects have been created so far.
b) For Yachts Location : Create a class Location that has three member variables ––
i) int for degrees (explained above)
ii) float for minutes (explained above)
iii) Char for direction letters N,S,E,W
Location class has variables like longitude and latitude. Location class
includes one member getpos() which obtains a location value in degrees
(between 0–180) and minutes (between 0 to 60) and direction (N,S,E,W) from
the user.
c) One member function [ get_pos() ] of the Yacht class should get a position from the
user and store it in the object; Another member function [ display() ] should report
the yacht number and location. display() use two variables from Location class to
represent the yacht’s location, latitude and longitude. display() function will display
the location latitude and longitude in 148°26’ N format.
d) The main() program creates three yachts, asks the user to input the location and
then displays each yacht’s number and location.
2. Prepare the UML class diagram for the Location class (LO1).
3. Clearly describe the process used to solve the problem with the help of appropriate
comments that increases the readability of the program (LO2).
Note: Use the hex character constant ‘\xF8’ to display a degree symbol (°). Sample
