🚀 Compiling and Linking in C: A Quick Guide

Ever wondered about the magic behind turning your C code into an executable? Let's demystify the process in a nutshell!

Preprocess C Code:

Generate an intermediate preprocessed file (.i) using gcc -E: gcc -E -o output.i input.c.
Compiling C to Assembly:

Use gcc with the -S option to generate an assembly (.s) file from the preprocessed file: gcc -S -o output.s output.i.
Compiling C to Object Code:

Assemble the assembly file into an object (.o) file using as: as -o output.o output.s.
Linking Object Files:

Link the object file(s) to create an executable using ld: ld -o output output.o.
Or Simply Use gcc:

Combine preprocessing, compilation, and linking in one step using gcc: gcc -o output input.c.
