Note!

This is a fairly complex program with detailed specifications. Please turn this program early for my comments!

Introduction

The program asks for input from the user, processes the information and displays its results back to the user using functions.

9. Star Search

A particular talent competition has five judges, each of whom awards a score between 0 and 10 (both 0 and 10 are considered valid!) to each performer. Fractional scores, such as 8.3, are allowed. A performers final score is determined by dropping the highest and lowest score received, then averaging the three remaining scores. Write a program that uses these rules to calculate and display a contestants score. It should include the following functions:

void getJudgeData() should ask the user for a judges score, store it in a reference parameter variable, and validate it. This function should be called by main once for each of the five judges. Make the following change to void getJudgeData( ).

The function should take in 2 parameters, not 1, as specified above

The first parameter should be a string that holds the values "Judge 1", "Judge 2".. and so on.

The second parameter should follow specifications shown above.

The getJudgeData function should ensure that:

score is numeric

score is >= 0

score is <= 10

double calcScore() getAverage() should calculate and return the average of the three scores that remain after dropping the highest and lowest scores the performer received. This function should be called just once by main and should be passed the five scores. Invoke the getLowest and getHighest function from this function in order to drop highest and lowest scores before calculating average.

In int main, invoke the getHighest, getLowest and getAverage functions and print out the values returned by these functions. Average, highest and lowest values must be printed in the int main function. All scores must be printed out to 2 places after the decimal place

Refer to the Programming Standards document and follow the rules stated there in order to complete the program.

Do not use the max and min functions that are part of Visual Studio!

The function prototypes to be used as as follows.

Do not change the function prototypes from the ones shown below. Your functions MUST match up with these prototypes!

void getJudgeData(string jname, double &score);

double getAverage(double score1, double score2, double score3, double score4, double score5);

double findLowest(double score1, double score2, double score3, double score4, double score);

double findHighest(double score1, double score2, double score3, double score4, double score5);

Make sure that the main function is the first function in the program listing. All other functions

should be placed after the main function!

should have function prototypes coded before the main function!

DO NOT USE ANY GLOBAL VARIABLES

Here is code illustrating the use of the getJudgeData functions:

int main()

{

double score1, score2, score3,score4, score5, average_sc, lowest_sc, highest_sc;

getJudgeData("Judge 1", score1);

getJudgeData("Judge 2", score2);

getJudgeData("Judge 3", score3);

getJudgeData("Judge 4", score4);

getJudgeData("Judge 5", score5);

.

.

... = getAverage(....);

... = findLowest(....);

... = findHighest(....);

cout <<....

return 0;

}

double getAverage(double score1, double score2, double score3, double score4, double score5)

{

= .... - findHighest(.....) - findLowest(.....)

}
