//
// You can force a loop to exit immediately with a "break" statement:
//
// while (condition) : (continue expression) {
//
// if (other condition) break;
//
// }
//
// Continue expressions do NOT execute when a while loop stops
// because of a break!
//
const std = @import("std");
pub fn main() void {
var n: u32 = 1;
// Oh dear! This while loop will go forever!?
// Please fix this so the print statement below gives the desired output.
while (true) : (n += 1) {
if (???) ???;
}
// Result: we want n=4
std.debug.print("n={}\n", .{n});
