 - The standard library provides essential data structures such as hash maps and array lists, whereas in C it is tempting to use linked lists for simplicity.
 - Advanced CPU features are enabled by default, unless [cross-compiling](#cross-compiling-is-a-first-class-use-case).

 ## Zig competes with C instead of depending on it
 
 The Zig Standard Library integrates with libc, but does not depend on it. Here's Hello World:

 In order to accomplish this, Zig programmers must manage their own memory, and must handle memory allocation failure.
