rustHow to iterate over pointer in Rust

To iterate over a pointer in Rust, you can use the .iter() method. This method returns an iterator over the pointer's elements. For example, if you have a pointer to an array of integers, you can use the .iter() method to iterate over the array:

let arr = [1, 2, 3];
let ptr = &arr;

for x in ptr.iter() {
    println!("{}", x);
}

This code will print out each element of the array, one per line. The .iter() method returns an iterator, which is a type of object that can be used to iterate over a collection of elements. The iterator will return each element of the array in turn, allowing you to process each element in the loop.

In addition to .iter(), Rust also provides the .iter_mut() method, which returns an iterator over mutable references to the pointer's elements. This can be used to modify the elements of the pointer in a loop.
