Rust Programming Tutorial #9 - For Loop

In this video we take a look at for loops in Rust, which are unconventional compared to other languages such as C or Java. In Rust, you use for loops to loop over iterators.

We also look at using the enumerate function to gain access to the index we are currently at in the loop.

I seriously don't understand why you don't have over 500k of subscribers ! I've been your videos for a while and you're one of the best youtubers there are that explain things amazingly. thank you !

Just discovered these, really enjoying them and easy to understand

[dp-mason]

Thank you for the videos!! I have a really difficult time reading books about this stuff, so I very much appreciate you explaining everything so clearly and concisely.

You deserve way more subs and views man, this is such a great channel and resource for people learning rust. Just wanted to say keep doing what you're doing!

This is the first video of the series where we digress a bit prematurely. You haven't introduced ownership at all, so the iter saga is a bit foggy to most I assume. I am looking for this ownership lesson but this so nice to watch that I think I will just continue one by one.

for loop in 1..11 loops from 1 to 10 by adding 1. My question is what we'd do if we wanted to iterate by more than 1 like in c we used for(i=1:i<=10;i++ or i+=1 or i+=2 or i+=3 or ...)


I am really thankful for your tutorials they're super easy and understandable for beginner. Big ups! <3

very nice series; thank you for sharing your knowledge

I have a question... (Great video for beginners btw!)
Why do we need the ".iter()" part? As you mention in the video it's because we want to reuse the "animals" variable.

But according to the variables video, can't we achieve the same thing with immutable referencing?
for a in &animals {...}

I tried it in an online compiler, and seems to work. Am I missing something?

range inclusive

let range= 1..=7;

for i in 1..=7 {}

What do you think of using the .for_each() method and a closure instead of a for loop ?

how to make a program for Fahrenheit to centigrade conversion through loop please help

[FPChris]

How to over complicate the tried and true “for loop”. JFC. No wonder C is still used. And what if you wanted to i+=5 on the index?

One note the semi quotes aren't compulsory as of now.

You haven’t explained vectors yet, so maybe link a video :)

[igorsilva]

let animals= vec!["conejo", "cao", "cato"];

for i in animals.iter()
{
print!("{}, ", i);
}

print!("{}", animals[0]); // run

[FPChris]

Great channel btw. I’m just bashing on how terrible this syntax it. Just awful.
