Loops

Overview of while and for.

Sum with for

while repeats while the condition is true. for i in a..b iterates a half-open range.

fn main() {
    let mut sum = 0
    for i in 0..5 {
        sum = sum + i
    }
    print(sum)
}

fn main() -> void {
    let mut sum: i32 = 0
    for i in 0..5 {
        sum = sum + i
    }
    print(sum)
}
