Intro

01

Compiler and interpreter.

The interpreter takes the program and some data produces output. This would be scripting.

A compiler takes the program and produces and executable. This executable can be run on the data.

• lexical analysis
• parsing
• semantic analysis
• optimization
• code generation

02

Lexing breaks input into tokens. Parsing produces a tree. Semantic analysis checks that the program is correct. Optimization makes it run faster and use less memory, or any number of resource balancing. Code generation produces code, generally machine code.
