//
// Check this out:
//
// var foo: u8 = 5; // foo is 5
// var bar: *u8 = &foo; // bar is a pointer
//
// What is a pointer? It's a reference to a value. In this example
// bar is a reference to the memory space that currently contains the
// value 5.
//
// A cheatsheet given the above declarations:
//
// u8 the type of a u8 value
// foo the value 5
// *u8 the type of a pointer to a u8 value
// &foo a reference to foo
// bar a pointer to the value at foo
// bar.* the value 5 (the dereferenced value "at" bar)
//
// We'll see why pointers are useful in a moment. For now, see if you
// can make this example work!
//
const std = @import("std");
pub fn main() void {
var num1: u8 = 5;
var num1_pointer: *u8 = &num1;
var num2: u8 = undefined;
// Please make num2 equal 5 using num1_pointer!
// (See the "cheatsheet" above for ideas.)
//num2 = num1_pointer.*;
num2 = num1_pointer.*;
std.debug.print("num1: {}, num2: {}\n", .{ num1, num2 });
