LAB $5$ USER$-$DEFINED SIMPLE DATA TYPES,

NAMESPACES AND STRING TYPE

OBJECTIVES

In this lab assignment, students will learn:

$-$ How to create a simple data type $($enumeration type$)$

$-$ How to use the operators with enum types

$-$ How to use the enum types in a control statement

$-$ How to write functions with enum types

$-$ How to use the namespace mechanism

COURSE PREPARATION

Read the following documents:

$$ Chapter $7$ of the lecture slides and textbook.

$$ CSC$134-$Coding Guidelines.doc posted in Course Resources $->$ Tutorials and Guidelines to Create and Submit C$++$ Programs.

GRADING RUBRIC

$$ Indent code and insert comments to document your program. $[10$ pts$]$

$$ Program must be implemented and run as instructed. Program that does not compile and run will not receive any credit. $[80$ pts$]$

$$ Submit the C$++$ programs to Blackboard correctly. $[10$ pts$]$

INSTRUCTIONS

$$ Create an empty C$++$ program YourLastname$\_$Lab$5,$ write code to create a report using icecream flavor ratings received from the attached text file flavors.txt$,$ which contains the customer$$s Last name, First name, score for vanilla, score for chocolate, score for strawberry, score for banana, score for oreo.

$$ The program should generate the Output Report File $$flavors$\_$report.txt$$ in the following format :

o Add a new header file $$Lab$5.$h$$ in the $$Header Files$$ folder : right$-$click Header Files $->$ Add $->$ New Item $->$ Header File $(.$h$).$

o Define a namespace $$icecream$$ in the $$Lab$5.$h$$ header file. The namespace should contain the following members:

o Define counter variables for each ice cream flavor and initialize each to $0$:

o Define the enum data type $$rating$$ to define customer$$s rating:

enum rating $\{$EXCELLENT$,$ GOOD, OK$,$ NOT$\_$GOOD, BAD$\}$;

o Define the enum data type $$flavors$$ to define flavors:

enum flavors $\{$VANILLA$,$ CHOCOLATE, STAWBERRY, BANANA, OREO$\}$;

o Define function getRating to determine customer$$s rating according to average score:

rating getRating$($double vScore, double cScore, double sScore, double bScore, double oScore$)$;

o Value$-$returning function.

o Requests the four scores $($vanilla$,$ chocolate, strawberry, banana, oreo$)$ as parameters.

o Calculates the average score.

o Based on average score, returns rating type data according to the following rules :

Average rating

$9\mathrm{.}0-10$ EXCELLENT

$7\mathrm{.}0-8\mathrm{.}9$ GOOD

$5\mathrm{.}0-6\mathrm{.}9$ OK

$3\mathrm{.}0-4\mathrm{.}9$ NOT$\_$GOOD

$0-2\mathrm{.}9$ BAD

o Define function getFavoriteFlavor to determine the highest score and its corresponding flavors type:

flavors getFavoriteFlavor$($double vscore, double cscore$,$ double sscore, double bscore, double oscore$)$;

o flavors $-$returning function

o Requests rating as parameter.

o Determines the highest rated flavor and return that enumerated flavors type

o Define function incrementFavoriteCounter and increment the counter for the given flavors type:

void incrementFavoriteCounter$($flavors favorite$)$;

o void$-$returning function

o Parameter: pass by value a flavors type.

o Increments the appropriate counter for the given flavors type

o Define function convertRateToMessage to convert a rating type to a string message.

string convertRateToMessage$($rating rate, flavors favFlavor$)$;

o Value$-$returning function

o Requests rating and flavors as parameter.

o Returns corresponding string rating and flavor.

o Create a source$/$main file that reads the flavors.txt file and calls the enumerated functions to produce the output file, flavors$\_$report.txt containing the information shown above.

o Compress the whole project folder into a zip file $$YourLastname$\_$Lab$5.$zip$$ and submit it through Lab $5$ link in Blackboard for credit.
