Overview of a 2-Dimensional Array (2D Array) Definition A 2-dimensional array, also known as a 2D array, is an array that has data spread out in two separate directions. In VBA, a 2D array is declared by specifying the number of rows and columns that it will have, and each element...
In memory, a 2-dimensional array is typically represented as a contiguous block of memory cells. The elements of the array are stored row by row, with each row occupying a continuous segment of memory. The memory map follows a row-major order, meaning that the elements of each row are st...
