Hardware data storage device developed by Iomega that functions
like a Standard 1.44" floppy drive. What makes the Iomega zip drive
unique is its capability to hold up to 100 MB of data or 250 MB of data on new
drives. Iomega Zip Drives became very popular in late 1990s, however, became
less popular as users needed larger storage capabilities. This drive was later
replaced by larger and cheaper CD-R and CD-RW drives and discs.
In the picture to the right, is an example of an Iomega Zip diskette. This
diskette is bigger than the standard floppy diskette and is made out of a much
harder plastic.
Pointers are an extremely powerful programming tool. They can make some things much easier, help improve your program's efficiency, and even allow you to handle unlimited amounts of data. For example, using pointers is one way to have a function modify a variable passed to it. It is also possible to use pointers to dynamically allocate memory, which means that you can write programs that can handle nearly unlimited amounts of data on the fly--you don't need to know, when you write the program, how much memory you need. Wow, that's kind of cool. Actually, it's very cool, as we'll see in some of the next tutorials. For now, let's just get a basic handle on what pointers are and how you use them. What are pointers? Why should you care? Pointers are aptly name: they "point" to locations in memory. Think of a row of safety deposit boxes of various sizes at a local bank. Each safety deposit box will have a number associated with it so that you ca...
