What is :- Assembler , compiler , Preprocessor , laxical analysis , parsing ?

Assembler , compiler , Preprocessor are the tools used during compilation. Lots of details are involved to discuss this. To answer in short, source files will undergo preprocessing, compiling (proper), assembling and linking to produce an executable object file. Lexical analysis and parsing are the internal steps. read less

Assembler: An assembler is a type of computer program that interprets software programs written in assembly language into machine language, code and instructions that can be executed by a computer. Compiler: A compiler is a computer program (or a set of programs) that transforms source code written in a programming language (the source language) into another computer language (the target language), with the latter often having a binary form known as object code Preprocessor: The C Preprocessor is not a part of the compiler, but is a separate step in the compilation process. In simple terms, a C Preprocessor is just a text substitution tool and it instructs the compiler to do required pre-processing before the actual compilation. We'll refer to the C Preprocessor as CPP. Laxical Analysis: Lexical analysis is the first phase of a compiler. It takes the modified source code from language preprocessors that are written in the form of sentences. The lexical analyzer breaks these syntaxes into a series of tokens, by removing any whitespace or comments in the source code. Parsing: Parsing or syntactic analysis is the process of analysing a string of symbols, either in natural language or in computer languages read less
