## 3-dimensional arrays

Hi. I receive unexpected outcome in my programm. Instead of geting all combinations of 0, 1, 2 (i.e. 000, 001, ..., 222) I get only 000 001 002 010 011 012. Can somebody tell me why?
The idea of the progarmm is to create a crystal lattice. Each atom of the lattice has 3 coordinates (x, y, z). That's why I create class Atom. Then I create 3-dim array of the type derived from class Atom. Now each element of the class will represent an atom. If somebody has an idea how to implement it in a more sophisticated way, I will appreciate it. Thanks in advance!
Code:
```#include <iostream>

using namespace std;

class Atom
{
public:

float x, y, z;
};

typedef class Atom AtomType;

int main ()
{
float a=1; // lattice parameter
int Lx=2, Ly=2, Lz=2; // number of translated lattices along each axis

AtomType ***Atom1; // 3-dimensional dynamic array for atom type 1

Atom1 = new AtomType** [Lx];

for (int i=0; i<Lx; i=i+a) // start of for loop
{
Atom1[i] = new AtomType* [Ly];
} // end of for loop
for (int i=0; i<Lx; i=i+a) // start of the outer for loop
{
for (int j=0; j<Ly; j=j+a)
{
Atom1[i][j] = new AtomType [Lz];
}
} // end of the outer for loop
cout << "Atom1:" << endl;
for (int i=0; i<=Lx; i++) // start of the 3 nested for loops to populate atoms of type 1
{
for (int j=0; j<=Ly; j++)
{
for (int k=0; k<=Lz; k++)
{
Atom1[i][j][k].x = i*a;
Atom1[i][j][k].y = j*a;
Atom1[i][j][k].z = k*a;

cout << Atom1[i][j][k].x << "   " << Atom1[i][j][k].y << "   " << Atom1[i][j][k].z << endl;
}
}
} // end of the 3 nested for loops to populate atoms of type 1

for (int i=0; i<=Lx; i++) // start deleting array Atom1
{
for (int j=0; j<=Ly; j++)
{
delete[] Atom1[i][j];
}
}
for (int i=0; i<=Lx; i++)
{
delete[] Atom1[i];
}
delete[] Atom1; // end of deleting array Atom1

return 0;
}```
