C_Basics

Just some code to track some basics of the C language for personal reference.

Topics include

• Header Files
• Global Variables
• Static Variables
• "sizeof" variables, pointers and structures
• Dynamic Memory - Malloc() and Free()
• Pointers
  • returned from functions
  • dereferencing
  • generic pointers (void *ptr)
  • passing data into/out of functions
  • passing functions with pointers (functional programming)
  • passing arrays into functions - this is done using pointers
• Arrays
  • passed to functions

To Do:

• Figure out the size of functions (stack size) - this is done through linker/compiler options
• Pointers: passing stings and arrays to functions
• type casting
  • pointers: addr= (structure_name *)function(function_input);

How To Run

Compiled using GCC on Windows 10

"gcc Header_Functions.c Header_Test.c Pointer_Functions.c -o header_out"

Run by executing

"header_out"
