How to declare a two-dimensional array?

Question

C++ / C#

Can an array be declared in this way ? byte[][] iter_num = new byte[16][32];

Answer 1

if you need a square array then

byte[,] iter_num = new byte[16, 32];
iter_num[1,2] = 1;

if you need an array of arrays then already

byte[][] iter_num = new byte[16][];

for (var i=0; i<iter_num.GetLength(0); i++)
{
     iter_num[i] = new byte[32];
}
iter_num[1][2] = 1;
