Problem:

Write a program that calculates the average of a group of test scores, where the lowest score in the group is dropped.

       It must have the following functions:

    - void getScore() should ask the user for a test score, store it in a reference parameter variable, and validate it.

         This function must be called by main once for each of the six scores to be entered (so 6 times).

         - Validate the test scores entered are greater than or equal to 0 and less than or equal to 100

    - Void calcAverage() should calculate and display the average of the five highest scores.

      This function must be called just once by main, and must be passed the six scores.

      Result must be displayed with a precision of 2.

    - int findLowest() should find and return the lowest of the lowest scores passed to it.

         It must be called by calcAverage, which uses the function to determine which of the six scores to drop.

Solution:

#include <iostream>

#include <iomanip>

using namespace std;

void getScore(int &);

void calcAverage(int, int, int, int, int, int);

int findLowest(int, int, int, int, int, int);

int main() {

              int score1,

              score2,

              score3,

              score4,

              score5,

              score6;

       for (int i = 0; i < 6; i++){

              if (i == 0) {

                     getScore(score1);

              }

              else if (i == 1) {

                     getScore(score2);

              }

              else if (i == 2) {

                     getScore(score3);

              }

              else if (i == 3) {

                     getScore(score4);

              }

              else if (i == 4) {

                     getScore(score5);

              }

              else if (i == 5) {

                     getScore(score6);

              }

       } // end of for loop

       calcAverage(score1, score2, score3, score4, score5, score6);

       system("pause");

       return 0;

}

void getScore(int &score) {

       int validate;

       cout << "Score test input required: ";

       cin >> validate;

       while ((validate < 0) || (validate > 100)) {

              cout << "Test scores must be inbetween between 0 and 100." << endl

                     << "Renter score test input: ";

              cin >> validate;

       }

       score = validate;

}

void calcAverage(int score1, int score2, int score3, int score4, int score5, int score6) {

       int dropScore = findLowest(score1, score2, score3, score4, score5, score6);

       int sum = score1 + score2 + score3 + score4 + score5 + score6 - dropScore;

       double average = sum / 5.0;

       cout << setprecision(2) << fixed << showpoint;

       cout << "Result: average score: " << average << endl;

}

int findLowest(int score1, int score2, int score3, int score4, int score5, int score6) {

       int lowestScore;

       if (score1 <= score2) {

              lowestScore = score1;

       }

       else {

              lowestScore = score2;

       }

       if (score3 < lowestScore) {

              lowestScore = score3;

       }

       if (score4 < lowestScore) {

              lowestScore = score4;

       }

       if (score5 < lowestScore) {

              lowestScore = score5;

       }

       if (score6 < lowestScore) {

              lowestScore = score6;

       }

       return lowestScore;

}
