To repeat an expression in Zig, while loops can be used. |
|
![]() const std = @import("std"); const print = std.debug.print; |
|
pub fn main() anyerror!void { |
|
The body of a while loop will repeatedly execute until the while loop’s condition is no longer true. |
var i: usize = 0; while (i < 2) { print("i: {}\n", .{i}); i += 1; } |
While loops support continue expressions, which are evaluated each time the loop’s body is executed. |
var j: usize = 0; while (j < 2) : (j += 1) { print("j: {}\n", .{j}); } |
To break out of a while loop, use the |
while (true) { break; } |
To jump to the next iteration of a while loop, use the |
var k: usize = 0; while (true) : (k += 1) { if (k < 2) { print("k: {}\n", .{k}); continue; } |
break; } } |
$ zig run while.zig i: 0 i: 1 j: 0 j: 1 k: 0 k: 1 |
