//
// Continue expressions do NOT execute when a while loop stops
// because of a 'break' statement.
//
// Example:
//
// while (condition) : (continue expression){
// if(other condition) break;
// ...
// }
//
const std = @import("std");
pub fn main() void {
var n: u32 = 1;
// Oh dear! This while loop will go forever!?
while (true) : (n+=1) {
if(???) ???;
}
// Result: we want n=4
std.debug.print("n={}\n", .{n});
}
