Recently a Twitter user posted a project they had been working on where they implemented a multi-dimensional array to store frames of a movie. They used the variable int ****video to store this data, and were immediately mocked by software Twitter. This is definitely the wrong way to do multi-dimensional arrays, but I’ve also seen material, even textbooks, that incorrectly teach it this way. I can easily imagine the above-mentioned Twitter user was simply taught wrong. (In fact, I think it’s very likely.) So today I want to talk about the correct way to do multi-dimensional, dynamically sized arrays
