//
// An anonymous struct value LITERAL (not to be confused with a
// struct TYPE) uses '.{}' syntax:
//
// .{
// .center_x = 15,
// .center_y = 12,
// .radius = 6,
// }
//
// These literals are always evaluated entirely at compile-time.
// The example above could be coerced into the i32 variant of the
// "circle struct" from the last exercise.
//
// Or you can let them remain entirely anonymous as in this
// example:
//
// fn bar(foo: anytype) void {
// print("a:{} b:{}\n", .{foo.a, foo.b});
// }
//
// bar(.{
// .a = true,
// .b = false,
// });
//
// The example above prints "a:true b:false".
//
const print = @import("std").debug.print;
pub fn main() void {
printCircle(.{
.center_x = @as(u32, 205),
.center_y = @as(u32, 187),
.radius = @as(u32, 12),
});
}
// Please complete this function which prints an anonymous struct
// representing a circle.
fn printCircle(???) void {
print("x:{} y:{} radius:{}\n", .{
