I'm going through 'build your own Lisp' and these are some of my notes.
- function definition
- functions do things, take things in, give things back
- structure definition
- custom data types
- main
- a c program always starts from the main function
A program in C consists of only functions and structure definitions.
To compile run cc filename.c
This creates an a.out file. To execute run ./a.out
To specify a name instead of the default a.out, use -o. -std=c99 specifies the version.
cc -std=c99 -Wall hello.c -o hello_world
Run with ./c/hello/hello_world.
Under /c is my example c code.
