Macro Level Roadmap

Now we can start understanding the low level architecture fueling Hello, World!\n.

This is the source we are going to analyze ~

hello.c

#include<stdio.h>

int main(void){
  printf("Hello, World!\n");
}

We are going to have a look at the:

1. generated assembly (x86_64 Intel syntax),

2. object code,

   1. elf headers, and

   2. disassembly.

3. linked code (elf binary)

   1. elf headers, and

   2. disassembly.

4. Whole runtime picture (the real danger)
