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.

// Oops! This program is supposed to print a line like our Hello World
|
|
// example. But we forgot how to import the Zig Standard Library.
|
|
//
|
|
// The @import() function is built into Zig. It returns a value which
|
|
// represents the imported code. It's a good idea to store the import as
|
|
// a constant value with the same name as the import:
|
|
//
|
|
// const foo = @import("foo");
|
|
//
|
|
// Please complete the import below:
|
|
//
|
|
|
|
??? = @import("std");
|
|
|
|
pub fn main() void {
|
|
std.debug.print("Standard Library.\n", .{});
|
|
}
|
|
|
|
// Going deeper: imports must be declared as "constants" (with the 'const'
|
|
// keyword rather than "variables" (with the 'var' keyword) is that they
|
|
// can only be used at "compile time" rather than "run time". Zig evaluates
|
|
// const values at compile time. Don't worry if none of this makes sense
|
|
// yet! See also this answer: https://stackoverflow.com/a/62567550/695615
