In this program, we will create two arrays and initialize them with default values. Then we will print the arrays. Program/Source Code: The source code to initialize array elements with a default value is given
To declare an array in Rust, we specify the type and the number of elements enclosed in square brackets. Here's an example: let array: [i32; 5]; // Declares an array of 5 elements of type i32 C# Copy We can also initialize the array with specific values using the following syntax:...
Arrays are created with a pair of [] brackets. The array type is [T; length]. Array initializationIn the first example, we initialize arrays in Rust. main.rs fn main() { let vals: [i32; 5] = [1, 2, 3, 4, 5]; println!("{:?}", vals); let words = ["soup", "falcon",...

Array Declaration: let arr: [i32; 3]: Declares a variable named arr of type array ([i32; 3]). i32 specifies the type of elements in the array (32-bit signed integers). 3 specifies the length of the array. Array Initialization: = [1, 2, 3];: Initializes the array with three ele...
