 We will focus on common errors, caveats and important concepts that might ease your cognitive overhead when you program in C. We will also recommend some tools that help you speed up your development and debugging.
 
-## C Compilation Process
-
-Unlike other interpreted programming languages, we use compilers to compile C written programs.
-
-A full compilation in C is depicted in the following figure:

-## C Macros
-
-You often see C preprocessor macros defined to create "small functions"
-
-But they **aren't actual functions**, it just changes the **text** of the program.
-
-`#include` just copies that file into the current file and replace the arguments.
-
-Example:
-
-```c
-#define twox(x) (x + x)
-
-// twox(3); => (3 + 3);
-
-// this could lead to unexpected behaviours
-// int y = 2;
-// int z = twox(y++); => z = (y++ + y++);  the value of z actaully depends on the order of evaluation

 ## Specific Sized Numbers
 
 C only guarantees minimum and relative size of "int", "short" etc... The range that each type can represent depends on the implementation.
