3.2. Add the boot code to the TEXT.O to make it a machine language program that can be run

directive:cc TEXT.O

Normally a machine language program called A.out is generated (this process is called a link)

You can also directly cc text.c, and then generate a.out, omitting the steps to generate. O.
