Here is a full summary of the key concepts organised by unit: UNIT 1: Introduction to Compiler Compiler and its Phases A compiler is a translator that converts high-level language (HLL) into machine language. Its main goal is to transform code without changing its meaning and to report errors. Compilation executes in two parts: translating the source program into an object program (low-level language), and then translating the object program into the target program using an assembler. The compilation process involves six main phases: Lexical Analysis (Scanner): Reads source code character-by-character, converting it into meaningful lexemes and re...
