Void Pointers
The void pointer is a generic pointer type. A pointer to void can store an address to any non-function data type, and, in C is implicitly converted to any other pointer type on assignment, but it must be explicitly cast if dereferenced inline.
dynamic memory allocation (malloc/free)
dynamic memory allocation is the task of allocating a free chunk of memory specific to the size you predetermine in bytes, by using the malloc function. The chunk of memory is not always in the same location hence being “dynamic” instead of static. By using the “free” function, that will release the block of memory back to the system.

If you wish to aid your definition with a code sample, you can do so by using a wiki code block, an example follows:
/* * Sample code block */ #include <stdio.h> int main() { return(0); }
Alternatively (or additionally), if you want to demonstrate something on the command-line, you can do so as follows:
lab46:~$ cd src lab46:~/src$ gcc -o hello hello.c lab46:~/src$ ./hello Hello, World! lab46:~/src$
File Compression.
involves encoding information using fewer bits than the original file. It helps reduce resources usage such as data storage space or transmission capacity. In order to use the data again though you must uncompress the file.
Links to Files

How important are DLL files?

Collect information and resources (such as URLs of web resources), and comment on knowledge obtained that you think will provide useful background information to aid in performing the experiment.
Without any .dll files, certain programs will stop functioning properly.
After downloading files, many have additional extensions in the .dll format. Without these they might not be able to function fully.
Im going to find a simple file with .dll extensions and see what happens after I delete a few of these files one by one.
Based on the data collected:
The conclusion that I'm having is that although you can run certain files without there extensions, it isn't very wise. Therefor .dll files are quite important in dealing with files that need them.
