Report Card V4 - Multiple Students in Go

Practice

Combine lists, loops, and conditionals to print a letter grade for each student in a class.

You start with:

names := []string{"Alice", "Bob", "Carol", "Dan"}
scores := []int{92, 78, 85, 67}

Build:

Alice: A
Bob: C
Carol: B
Dan: D

Rules:

Loop over the indices of the students (len(names)) so you can read the name and the score at the same position.
Use the same scale as V3: 90+ A, 80-89 B, 70-79 C, 60-69 D, below 60 F.
On each iteration print the name, a colon and a space, then the grade, for example Alice: A.

Use []string and []int slices with index loops.

names := []string{"Alice", "Bob", "Carol", "Dan"}
scores := []int{92, 78, 85, 67}

for i := 0; i < len(names); i++ {
    score := scores[i]
    var grade string
    if score >= 90 {
        grade = "A"
    } else if score >= 80 {
        grade = "B"
    } else if score >= 70 {
        grade = "C"
    } else if score >= 60 {
        grade = "D"
    } else {
        grade = "F"
    }
    fmt.Println(names[i] + ": " + grade)
}
