I have been assigned to write a program that utilizes functions. I must use a function to acquire 6 test scores, a function to drop the smallest value of the test scores, and then a function to calculate the average of the 5 highest test scores. Then call each function in main. I think I have the program mostly figured out just need help understanding how to exclude the lowest number. Any help would be greatly appreciated. Here is my code the function I'm working on is in line 88. Also I am getting a warning about the { in line 90 and 95 that states "expected a declaration," could someone fill me in on what that is implying.
/* This Program calculates the average of a group of test scores where the lowest score in the group is dropped.
It will ask the user for a test score, store it in a reference parameter variable, and validate it.
This function will only be called by the main once for each of the six scores to be entered. (So 6 times)
It will validate that the test scores are >= 0 and <= 100.
calcAverage should calculate and display the average of the five highest scores. This function is to be called just once by main,
and must be passed the six scores.
int findLowest should find and return the lowest of the lowest scores passed to it. It will be called by calcAverage, which uses the function
to determine wich of the six scores to drop.*/

"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)." This is a quote from my assignment. The way I understand it is I have to write it 6 times, does this actually mean I just need to call it in main 6 times. I know there are better ways to create a program for this outcome but it is for a homework assignment.
// int& score : reference to int parameter
void getScore(int& score)
{
std::cout << "What is the test score? \n";
std::cin >> score;
if(score <= 0 || score >=100) {
std::cout << "Error! Please enter a test score value between 0 & 100. \n";
score = -1; // -1 to indicate an error
}
}
I don't think your teacher would want you to create a function six times, when you can just create it once and call it six times.
