// Oh no! This program is supposed to print "Hello world!" but it has some
|
|
// mistakes. Let's fix it.
|
|
//
|
|
// We're trying to import the Standard Library into the top level of our
|
|
// application. The standard library is not named "foo", it is named "std".
|
|
//
|
|
// Please correct the name in both places in the import here:
|
|
const foo = @import("foo");
|
|
|
|
// Zig applications start by calling a function named 'main'. It needs to be
|
|
// public so that it is accessible outside our file!
|
|
//
|
|
// Public functions are declared with the 'pub' keyword like so:
|
|
//
|
|
// pub fn my_function() void { ... }
|
|
//
|
|
// Please make the main() function public:
|
|
fn main() void {
|
|
|
|
// The easiest way to display our "Hello world" message in the
|
|
// terminal is to use the std.debug.print() function.
|
|
|
|
// Please fix this silly "foo" mistake here:
|
|
foo.debug.print("Hello world!\n", .{});
|
|
|
|
// The print function above takes two values:
|
|
//
|
|
// 1. A string of characters: "Hello world!\n". "\n" prints a new line.
|
|
//
|
|
// 2. A struct containing data to be displayed. .{} is an empty, nameless
|
|
// struct fulfilling the requirement. More about structs later.
|
|
//
|
|
//
|
|
// Now we're ready to...What's this!? Oh, we wanted to print a Goodbye
|
|
// message as well!
|
|
//
|
|
// Please fix this to use the same print function as above:
|
|
"Goodbye!\n"
|
|
}
|
|
|
|
// Once you're done with the changes above, run `ziglings` to see if it passes.
|
|
//
|
|
// Finally, all files will contain the following comment:
|
|
//
|
|
// I AM NOT DONE
|
|
//
|
|
// Delete it when you're ready to continue to the next exercise!
