C Programming Preprocessor
The C Preprocessor
Lines that begins with a # are called preprocessing directives.
#define LIMIT 100
The identifier LIMIT is called the symbolic constant.
#include <stdio.h>
<> indicates that the file is to be found in the system path. The preprocessor looks for the file only in the system path and not in the current directory.
#include "my_file.h"
The quotes surrounding the name of the file are necessary. A search for the file is made first in the current directory and then in other system-dependent places.

C Programming Naming Conventions
"""The C++ standard library often uses an underscore as a word separator (e.g. out_of_range). Identifiers representing macros are, by convention, written using only upper case letters and underscores (this is related to the convention in many programming languages of using all-upper-case identifiers for constants). Names containing double underscore or beginning with an underscore and a capital letter are reserved for implementation (compiler, standard library) and should not be used (e.g. reserved__ or _Reserved)."""

Excerpts from "Head First C"
=====
scanf("%79[^\n]", line")
It means read up to 79 characters, so long as they're not NEWLINES.
=====
For free text input use fgets().
char line[80];
fgets(line, 80, stdin);
printf("Your quote was: %s", line);
=====
The stack is the section of memory used for local variable storage. Every time you call a function, all of the function's local variables are created on the stack. Variables are added to the stack when you enter a function, and get taken off the stack when you leave.
=====
The heap is for dynamic memory - pieces of data that get created when the
progeam is running and then hang around a long time.
=====
The code segment is the part of the memory where the actual assembled code gets loaded.
=====
printf("I like Turtles!"); is the simplified version of fprintf(stdout, "I like Turtles!");
=====
">" redirects the Standard Output. But "2>" redirects the Standard Error.
=====
i % 2 means "The remainder left when you divide by 2".
=====
FILE* in_file = fopen("input.txt", "r");
FILE* out_file = fopen("output.txt", "w");
fprintf(out_file, "Don't wear %s with %s", "red", "green");
fscanf(in_file, "%79[^\n]\n", sentence);
fclose(in_file);
fclose(out_file);
=====
int main(int argc, char* args[])
{
.... Do stuff....
}
The first argument contains the name of the program as it was run by the user.
=====
file accessibility sanity check:
FILE* in;
if (!(in = fopen("dont_exist.txt", "r"))) {
fprintf(stderr, "Can't open the file.\n");
return 1;
}
=====
After processing the arguments, the 0th argument will no longer be the program name.
=====
To avoid ambiguity, you can split your main arguments from the options using "--". So you would write "set_temperature -c -- -4". getopts() will stop reading options when it sees the "--", so the rest of the line will be read as simple arguments.
=====
When we tell the compiler about a function it's called a function declaration. C allows you to take that whole set of declarations out of your code and put them in a header file.
=====
When the compiler sees an include line with angle brackets it assumes it will find the header file somewhere off in the directories where the library code lives. But our header file is in the same directory as our .c file. By wrapping the header file name in quotes we are telling the compiler to look for a local file.
=====
What if you want to share variables? Source code files normally contain their own separate variables to prevent a variable in one file affecting a variable in another file with the same name. But if you genuinely want to share variables, you should declare them in your header file and prefix them with the keyword extern.
=====
Every file that make compiles is called a target.
For every target, make needs to be told two things:
=====
All the recipe lines MUST begin with a TAB character. If you just try to indent the recipe lines with spaces, the build won't work.
=====
Make takes away a lot of the pain of compiling files. But if you find that even make is not automatic enough, take a look at a tool called autoconf:
http://www.gnu.org/software/autoconf/. Autoconf is used to generate makefiles.

Excerpts from the book of "The C programming language"
"A character written between single quotes represents an integer value equal to the numerical value of the character in the machine’s character set. This is called a character constant, although it is just another way to write a small integer."
"Parameter names need not agree. Indeed, parameter names are optional in a function prototype, so for the prototype we could have written int power(int, int);"
"""One aspect of C functions may be unfamiliar to programmers who are used to some other languages, particulary Fortran. In C, all function arguments are passed ‘‘by value.’’ This means that the called function is given the values of its arguments in temporary variables rather than the originals. This leads to some different properties than are seen with ‘‘call by reference’’ languages like Fortran or with var parameters in Pascal, in which the called routine has access to the original argument, not a local copy."""
"The story is different for arrays. When the name of an array is used as an argument, the value passed to the function is the location or address of the beginning of the array - there is no copying of array elements. By subscripting this value, the function can access and alter any argument of the array."
