Firstmate commented on a Page, dynamic multidimensional arrays Example  -  May 02, 2012

I'm not sure if this was done more out of demonstrating the code, but why not take:

``````    double ***ptr3;
ptr3 = new double**[2];
for( int i = 0 ; i < 2 ; i++)
{
ptr3[i] = new  double*[3];
}
for( int i = 0 ; i < 2 ; i++)
{
for( int j = 0 ; j < 3 ; j++)
{
ptr3[i][j] = new  double[4];
}
}

for( int i = 0 ; i < 2 ; i++)
{
for( int j = 0 ; j < 3 ; j++)
{
for( int k = 0 ; k < 4 ; k++)
{
ptr3[i][j][k] = ( i * 3 + j ) * 4.1 + k * 0.1;
}
}
}
``````

And make it:

``````    double ***ptr3;
ptr3 = new double**[2];
for( int i = 0 ; i < 2 ; i++)
{
ptr3[i] = new  double*[3];
for( int j = 0 ; j < 3 ; j++)
{
ptr3[i][j] = new  double[4];
for( int k = 0 ; k < 4 ; k++)
{
ptr3[i][j][k] = ( i * 3 + j ) * 4.1 + k * 0.1;
}
}
}
``````
