Multidimensional Arrays:

int [,] shuzuming=new int[5,3] //has 5 one-dimensional array of length 3

When a two-dimensional array reads, the comma is the y-axis, followed by the x-axis (one-dimensional array)

int[,] second = new int[2, 3] {{3, 2, 5}, {6, 7, 8}};

Second[0,1]=9 is replaced with a value of 9 at (1,0) coordinates

Age, height, name, number, average age, height sort
