In Rust, arrays are fixed-size collections of elements of the same data type. They are stored in contiguous memory locations, providing efficient access and modification. Arrays are created using the syntax [T; N], where T is the type of the elements and N is the number of elements in the array. Arrays can be indexed using the [] operator, and their length can be accessed with the .len() method.
This code demonstrates how to create an array, read user input to fill the array, display the array elements, and calculate the sum of the array elements in Rust.
