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!?
