Report Card V4 - Multiple Students in Swift

Practice

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

You start with:

let names = ["Alice", "Bob", "Carol", "Dan"]
let scores = [92, 78, 85, 67]

Build:

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

Rules:

Loop over the indices of the students (names.indices) 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 Swift arrays and for i in 0..<names.count.

let names = ["Alice", "Bob", "Carol", "Dan"]
let scores = [92, 78, 85, 67]

for i in names.indices {
    let score = scores[i]
    var grade = ""
    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"
    }
    print("\(names[i]): \(grade)")
}
