1D, 2D and Jagged Arrays
We introduce the three array varieties available in .NET: one-dimensional, multi-dimensional, and jagged arrays, using an image manipulation scenario to motivate the comparison. The lesson explains the syntax differences and the jagged-array initialization loop, setting up an investigation of which approach is fastest for pixel access.
