array of class

[ar2007]

hi.
I can not find a satisfactory explanation for the dynamic memory management with an array of class.
can anyone help me?

I know this but don't understand why "pointer to pointer"

myclass **mc = new mc*[5];

for (int i = 0; i < 5; ++i)
      mc[i] = new mc[6];     

Thx

First of all this code is invalid

myclass **mc = new mc*[5];

for (int i = 0; i < 5; ++i)
      mc[i] = new mc[6];

Should be

myclass **mc = new myclass*[5];

for (int i = 0; i < 5; ++i)
      mc[i] = new myclass[6];

If you are allocating an array dynamically then operator new returns pointer to the first element of the array,

As in your example the element type of array new myclass*[5] is myclass* then the pointer to an object of type myclass* will be myclass**

it is true. I found the code in http://www.cplusplus.com/forum/general/2609/ ... but I copied the wrong one.

in this link, the user asked for the dynamic memory for an array of class 2D. but for a 1D array, the same holds true? thanks for the reply
