//
// Zig 'while' statements create a loop that runs while the
// condition is true:
//
// 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 a equals b
// a < b a is less than b
// a > b a is greater than b
// a !=b a does not equal b
//

// Print the current number

// Set n to n multiplied by 2
n *= 2;
}
// Make this print n=1024
std.debug.print("n={}\n", .{n});
