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;
if x == 10 {
println!("x is ten!");
} else {
println!("x is not ten!");
}
}
