The Cousins of Compiler are listed as below. Pre-Processor Assembler Linker Loader Below described are the roles of cousins of the compiler Pre-processor : Preprocessor produces input to compiler. They may perform the following functions : Macro processing : A preprocessor may allow user to de for longer constructs. File inclusion: A preprocessor may include the header file into the program text. Rational preprocessor: Such a preprocessor provides the user with built in macro for construct like while statement or if statement. Language extensions: this processors attempt to add capabilities to the language by what amount to built in macros. Assembler : Assembler is a translator which takes the assembly program as machine code as a output. An Assembler is a mnemonic version of the machine code. Linker Linker allows us to make a single program from a several files of relocatable machine code. These file may have been the result of several different compilation, and one or more may be library files of routine provided by a system Loader The process of loading consists of taking relocatable machine code, altering the relocatable address and placing the altered instructions and data in memory at proper location
