fn main() {

// The easiest way to fix the compiler error is to initialize the
|

// variable `x`. By setting its value to an integer, Rust infers its type
|
|
// as `i32` which is the default type for integers.

let x = 42;

// But we can enforce a type different from the default `i32` by adding
|
|
// a type annotation:
|
|
// let x: u8 = 42;
