//
// Zig 'while' statements can have an optional 'continue expression'
// which runs every time the while loop continues (either at the
// end of the loop or when an explicit 'continue' is invoked (we'll
// try those out next):
//
// while (condition) : (continue expression) {
// ...
// }
//
// Example:
//
// var foo = 2;
// while (foo<10) : (foo+=2) {
// // Do something with even numbers less than 10...
// }
//
// See if you can re-write the last exercise using a continue
// expression:
//
const std = @import("std");
pub fn main() void {
var n: u32 = 2;
// Please set the continue expression so that we get the desired
// results in the print statement below.
while (n < 1000) : ??? {
// Print the current number
std.debug.print("{} ", .{n});
}
// As in the last exercise, we want this to result in "n=1024"
std.debug.print("n={}\n", .{n});
}
