Question

A particular talent competition has 5 judges, each of whom awards a score between 0 and
10 to each performer. Fractional scores, such as 8.3, are allowed. A performer’s final score
is determined by dropping the highest and lowest score received, then averaging the 3
remaining scores. Write a program that uses these rules to calculate and display a
contestant’s score. It should include the following functions:
• void getJudgeData() should ask the user for a judge’s score, store it in a reference
parameter variable, and validate it. This function should be called by main once for each
of the 5 judges.
• double calcScore() should calculate and return the average of the 3 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 5 scores.
Two additional functions, described below, should be called by calcScore, which uses the
returned information to determine which of the scores to drop.
