Summary of Understanding C program Compilation Process

Main Ideas and Concepts:

Compilation Process Overview:
The compilation of a C program involves multiple steps and components that work together to produce an executable file.
Components of a Compiler:
- Preprocessor
- Compiler
- Assembler
- Linker
Roles of Each Component:
- Preprocessor:
  - Removes comments from the code.
  - Includes header file code into the source file.
  - Replaces macro names with their corresponding values.
- Compiler:
  Takes the preprocessed file and generates assembly code, which uses mnemonics to represent instructions.
- Assembler:
  Converts assembly code into machine code (binary code), resulting in an object code.
- Linker:
  - Combines multiple object files into a single executable file.
  - Links library functions with the object code.
  - Supports two types of linking: static and dynamic linking.
Output Files:
The final output on Windows is typically an executable file with a .exe extension, while on Ubuntu, it is generated with a .out extension.

Step 1: Preprocessing
- Remove comments.
- Include header files.
- Replace macros with their values.
Step 2: Compilation
Generate assembly code from the preprocessed source file.
Step 3: Assembly
Convert assembly code into object code (machine language).
Step 4: Linking
Merge multiple object files into one executable file.

Link with any required library functions.
