Day 2 Mini-Project: Write a function that takes a List of int (e.g., student scores) and returns their average.

main.dart

// This function calculates the average of a list of scores.
double calculateAverage(List<int> scores) {
  if (scores.isEmpty) {
    return 0; // Avoid division by zero if the list is empty.
  }
  
  int total = 0;
  for (int score in scores) {
    total = total + score;
  }
  
  // The .length property gives us the number of items in the list.
  return total / scores.length;
}

void main() {
  List<int> studentScores = [88, 95, 74, 100, 81];
  double average = calculateAverage(studentScores);
  
  print("The student scores are: $studentScores");
  print("The average score is: $average");
}
