t's a critical lesson that today's computer science students aren't always being taught: How to carefully choose their high-level language statements to produce efficient code. Write Great Code, Volume 2: Thinking Low-Level, Writing High-Level shows software engineers what too many college and university courses don't - how compilers translate high-level language statements and data structures into machine code. Armed with this knowledge, they will make informed choices concerning the use of those high-level structures and help the compiler produce far better machine code - all without having to give up the productivity and portability benefits of using a high-level language.
