Dave Gauer adf5ddb27d Consistent instructions and examples
I started off with "hints" that required the poor student to piece
together the information from incomplete bits. A complete example is
like a picture that is worth 1000 words and far clearer.

//
// 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});
