You have a list of student grades. Your task is to calculate the average grade and determine the number of students with grades above 80.

Instructions

  • Use a for loop to iterate through the list and find:

    • The average grade.
    • The number of students with grades above 80.
  • Print the average grade and the number of students with grades above 80.

fun main() { val grades = listOf(75, 88, 92, 66, 80, 95, 72, 85) var sum = 0 var countAbove80 = 0 for (___ in ___) { sum = ___; if (grade ___) { // increment the count value } } val average = //divide sum by count of grades println("Average grade: $average") println("Number of students with grades above 80: $countAbove80") }
  • Use variables to store the sum of the grades and the number of students with grades above 80.
  • To calculate the average grade, use the formula: sum / count.
