\u00a0Language Processing System<\/strong><\/h3>\n

The Language Processing System<\/strong> is responsible for converting high-level programming code<\/strong> into machine-executable code<\/strong>. It consists of various phases, including Pre-processing, Compilation, Assembly, Linking, and Loading<\/strong>.<\/p>\n

\u00a0Stages of the Language Processing System<\/strong><\/h3>\n
\n\n\n\n\n\n\n\n\n\n\n
Stage<\/strong><\/th>\nFunction<\/strong><\/th>\n<\/tr>\n<\/thead>\n
Pre-Processor<\/strong><\/td>\nHandles macro expansion, header files, and conditional compilation<\/strong>.<\/td>\n<\/tr>\n
Compiler<\/strong><\/td>\nConverts high-level code<\/strong> (C, Java, Python) into assembly language<\/strong>.<\/td>\n<\/tr>\n
Assembler<\/strong><\/td>\nTranslates assembly language<\/strong> into machine code (object code)<\/strong>.<\/td>\n<\/tr>\n
Linker<\/strong><\/td>\nCombines multiple object files & libraries<\/strong> into a single executable.<\/td>\n<\/tr>\n
Loader<\/strong><\/td>\nLoads the executable file into memory<\/strong> for execution.<\/td>\n<\/tr>\n
Relocatable Code<\/strong><\/td>\nCode that can be loaded at any memory location<\/strong> instead of a fixed one.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

\u00a01. Pre-Processor<\/strong><\/h3>\n

\u00a0Handles macro processing, file inclusion, conditional compilation, and inline expansion<\/strong>.
\u00a0Works before compilation<\/strong>.<\/p>\n

Example in C (Using Preprocessor Directives):<\/strong><\/p>\n

\n
#include<\/span><\/span> <stdio.h><\/span> \/\/ File Inclusion<\/span>
\n#define<\/span><\/span> PI 3.14 \/\/ Macro Expansion<\/span>
\n<\/code><\/div>\n<\/div>\n

Output after Pre-processing:<\/strong><\/p>\n
