rustHow to iterate an array with index in Rust
Iterating an array with index in Rust can be done using the enumerate()
method. This method takes an iterator and returns each element of the iterator along with its index. The following example code block shows how to use enumerate()
to iterate an array with index:
let arr = [1, 2, 3];
for (index, value) in arr.iter().enumerate() {
println!("Index: {}, Value: {}", index, value);
}
The output of the above code is:
Index: 0, Value: 1
Index: 1, Value: 2
Index: 2, Value: 3
The ## Code explanation
-
let arr = [1, 2, 3];
: This line declares an array with three elements. -
for (index, value) in arr.iter().enumerate()
: This line uses theenumerate()
method to iterate the array and assign the index and value of each element to theindex
andvalue
variables respectively. -
println!("Index: {}, Value: {}", index, value);
: This line prints the index and value of each element.
