Report Card V6 - Class Statistics in Go

Practice

Compute three class statistics from a list of scores: the highest, the lowest, and the average.

You start with:

scores := []int{92, 78, 85, 67, 74, 88, 91, 58}

Build:

Highest: 92
Lowest: 58
Average: 79

Rules:

highest is the largest value in scores.
lowest is the smallest value in scores.
average is the sum of all scores divided by how many there are, rounded down (integer division).
Print "Highest: ", "Lowest: " and "Average: " on three lines, in the order of the sample output (fmt.Println("Highest: " + strconv.Itoa(highest))).

Iterate over the slice once, tracking max and min manually, and accumulate the sum.

scores := []int{92, 78, 85, 67, 74, 88, 91, 58}

highest := scores[0]
lowest := scores[0]
total := 0
for _, s := range scores {
    if s > highest {
        highest = s
    }
    if s < lowest {
        lowest = s
    }
    total += s
}
average := total / len(scores)

fmt.Println("Highest: " + strconv.Itoa(highest))
fmt.Println("Lowest: " + strconv.Itoa(lowest))
fmt.Println("Average: " + strconv.Itoa(average))
