How do I write a simple compiler?
I see. What are some of the basic components of a compiler?
A compiler typically has four main stages: Lexical Analysis, Syntax Analysis, Semantic Analysis, and Code Generation. Lexical Analysis involves breaking up the source code into individual tokens, such as identifiers, keywords, and symbols. Syntax Analysis uses these tokens to create a parse tree, which represents the structure of the program. Semantic Analysis checks the validity of the program and assigns meaning to each part of the code. Finally, Code Generation generates executable code from the parse tree.
