Wollw / c_object.c

Created November 2, 2011 10:51

A simple (if flawed) implementation of an object in C.

	/*
	* A simple example of an object in ANSI C.
	* It would be better to have initAdder simply call malloc
	* and return a pointer to the new object (and be preferable too)
	* as this would allow for freeing of objects too but for the sake of
	* simplicity I've opted to pass it a pointer instead.
	*
	* Note that with C++ the "this" variable is pretty much just implicit.
	*
	*/

Wollw / object_malloc.c

Created November 2, 2011 11:34

A simple implementation of an object in C using malloc an free for creation and destruction.

	/*
	* A simple example of an object in ANSI C.
	* This example uses malloc to create the new object.
	*
	* Note that with C++ the "this" variable is pretty much just implicit.

Wollw / insertat.c

Created February 14, 2012 01:09

insertion function example

	#include <stdio.h>


	/* This insertAt function takes an index to insert at "i",
	* a number to insert into the integer array "num", a pointer
	* to the current number of used spaces in the array "numUsed",
	* and a pointer to the array "a".
	*
	* This assumes that the array is big enough to insert a new element
	* for the sake of simplifying the example so it doesn't check against
