  • The Structure
    • C requires a compilation step, which consists of running a single command
    • Theres a standard library, and its part of your operating system
    • Theres a preprocessor
    • There are two types of comment
    • There is no print keyword
  • Variable Declarations
    • Variables have to be declared
    • Even functions have to be declared or defined
    • Basic types can be aggregated into arrays and structs
    • New structure types can be defined
    • You can find out how much space a type takes
    • There is no special string type
  • Expressions
    • The scoping rules for C are very simple
    • The main function is special
    • Most of what a C program actually does is evaluate expressions
    • Functions are evaluated using copies of the inputs
    • Expressions are delimited by semicolons
    • There are many shortcuts for incrementing or scaling a variable
    • C has an expansive definition of truth
    • Dividing two integers always produces an integer
    • C has a trinary conditional operator
    • Branching and looping expressions are not very different from any other language
    • The for loop is just a compact version of the while loop
  • Pointers
    • You can directly request a block of memory
    • Arrays are just blocks of memory; any block of memory can be used like an array
    • A pointer to a scalar is really just a one-item array
    • There is a special notation for elements of pointed-to structs
    • Pointers let you modify function inputs
    • Everything is somewhere, so everything can be pointed to
