A compiler is software that translates or converts a program written in a high-level language (Source Language) into a low-level language (Machine Language or Assembly Language). Compiler design is the process of developing a compiler.
- The Key objectives of compiler design are to automate the translation process, check correctness of input code, and reporting errors in source code.
- It acts as the "translator" of the programming world, bridging the gap between human-readable code and machine-understandable instructions.
- It involves many stages like lexical analysis, syntax analysis (parsing), semantic analysis, code generation, optimization, etc.
- Most of the early high level languages like C and C++ were compiled. However modern languages like Java and Python use both interpreter and compiler. Please note that compiler only translates but interpreter runs as well.
