Rust for Loop

In Rust, you can use the for loop to iterate over collections of items, such as arrays, vectors, and ranges. The basic syntax for a for loop is as follows:

for item in collection {
    // code to execute for each item
}

Here's an example of iterating over a range of numbers:

for num in 0..10 {
    println!("Number is {}", num);
}

In this example, we're iterating over a range of numbers from 0 to 9 (inclusive). Inside the loop, we're printing the current value of num using the println! macro.

You can also use a for loop with arrays or vectors. Here's an example using a vector:

let numbers = vec![1, 2, 3, 4, 5];

for num in numbers {
    println!("Number is {}", num);
}

In this example, we're iterating over a vector of numbers. The loop will execute once for each item in the vector, and the num variable will be set to the current item. We're then printing the value of num using the println! macro.

Note that when using a for loop with a collection, the loop will automatically iterate over each item in the collection, so you don't need to manually keep track of an index variable like you might in other languages.
