- //
- // Zig 'while' statements create a loop that runs while the
- // condition is true. This runs once (at most):
- //
- // while (condition) {
- // condition = false;
- // }
- //
- // Remember that the condition must be a boolean value and
- // that we can get a boolean value from conditional operators
- // such as:
- //
- // a == b means "a equals b"
- // a < b means "a is less than b"
- // a > b means "a is greater than b"
- // a != b means "a does not equal b"
- //
- const std = @import("std");
- pub fn main() void {
- var n: u32 = 2;
- // Please use a condition that is true UNTIL "n" reaches 1024:
- while (???) {
- // Print the current number
- std.debug.print("{} ", .{n});
- // Set n to n multiplied by 2
- n *= 2;
- }
- // Once the above is correct, this will print "n=1024"
- std.debug.print("n={}\n", .{n});
- }
