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.

Main.kt


              123456789101112131415161718
            
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.


              12345678910111213141516171819
            
fun main() {
    // Create a list of student grades
    val grades = listOf(75, 88, 92, 66, 80, 95, 72, 85)

    // Find the average grade and the number of students with grades above 80
    var sum = 0
    var countAbove80 = 0
    
    for (grade in grades) {
        sum += grade
        if (grade > 80) {
            countAbove80++
        }
    }
    
    val average = sum / grades.size
    println("Average grade: $average")
    println("Number of students with grades above 80: $countAbove80")
}
