What should I write to set dinamyc rectangular array length in
both dimentions?
For example, I have declareted an array:
``` int[][] matrix;```
and want set it as n*n matrix.
Thanks
There are many ways to do this, but I can quickly show you two:
```d
import std.stdio;
void main()
{
int[][] matrix;
enum n = 6;
// method 1:
//matrix = new int[][](n, n); /*
// method 2:
matrix.length = n;
foreach(ref e; matrix)
e.length = n;//*/
matrix.writeln;
}
```
