How do I add together all of the values from a for loop in Rust?

Question

    for mut i in 0..448 {
    i += 179;
    println!("{}", i)

How can I add all of the values that get printed to the terminal when this is ran?

What is this even supposed to be? Why would you write a loop like that rather than directly giving it a range of `179..627` (or `179..=626`)? Also, you need to include complete code blocks in your example code; where are the closing brackets? — Herohtar, Aug 12 '21 at 19:30

    fn main() {
    let a = 179..627;
    let sum: i32 = a.into_iter().sum();
    println!("the total sum is: {}", sum);

this worked

Ranges are already iterators, so there is no need for `into_iter()`. The extra variable assignment is unnecessary as well. You can compute the sum with literally just `(179..627).sum()`. – Herohtar Aug 12 '21 at 19:41
