An int[][][] x is a two-dimensional array of five rows and three columns. This means that there are 10 elements in total. -Every element is a char[] of length two. Every row, and every column has the same size (i.e., five). The first three columns are one dimensional arrays: x[0][], x[0][]=x[0], etcetera up to x[]. -The last four elements in each row are ints; this means that there are 20 integers total within an integer array with dimensions (int height) by (char width): i.e., rows * cols = number of items on each side, ix=number of rows *cols^(height-width)). For example, if you have an int array with dimensions (100*25), then it would contain 100 rows and 25 columns of integers. -To summarize: an int[][] has a height, width, and number of items on each side equal to (height * width). The first three dimensions are char arrays; the last dimension is an integer array with the same size as its surrounding sides. In other words, it can be expressed as [char row*cols][int item_size]. An int[][] x is a two-dimensional array of five rows and three columns. This means that there are ten elements in total. Every element is a char[] of length two. Every row and every column has the same size (i.e., five) – this means that there are twenty integers total within
