Some people have looked through the guidance for the new computing curriculum and have asked me what a Multi-Dimentional / Two Dimensional Data Structure is. Using OfficeMix, I have managed to produce a quick video which shows what a single data structure looks like. I have used an Array for this example. I have moved on to explain how Two-Dimensional Array’s work. This video should give you a rough idea.
The reason we use them is so that we can organise our data in a way which is easy to use/sort when programming. It would be much easier to increase the position of the Array by one using a variable. If we had 5,000 different variables it would be difficult to trace each one. This is why we use Array’s as a Multi-Dimensional Data Structure.
