What happens when you type gcc main.c
Why do we need to compile a program?
What is a Compiler?
A compiler its a program that translates an hight level language into a machine language (combinations of 0s and 1s), this process its called compilation.
Pre-Processor
In this step it verifies the following
-All the lines in your code starting with the pound (#) character which is known as macros or #define directives.
-Expands included files
-Ignores comments
To stop the gcc compiler at the end of this step we do
gcc -E [ File.c ]Compiler
Takes the output of the preprocessor and generates assembly language
To stop the gcc compiler at the end of this step we do
gcc -S [ File.c ]Generating a File.s file
Assembler
In this step the code its converted into 0s and 1s
To stop the gcc compiler at the end of this step we do
gcc -c [ File.c ]Generating a File.o file
Linker
This is the last step it merges all the object code from multiple modules into a single one and add the library functions if we are using some
