c++ array[var][2] as a class member -

I have an array of unsigned integers within a square, and its size should be [var] [2], then user In order to be able to choose var.

  Unsigned integer (* * * * * * * *] hashFunc);   
 and in the starting function:  
  hashfank = new unsigned int * [var]; (Unsigned int i = 0; i & lt; var; ++ i) hashfank [i] = new unsigned complete [2];   
 I just want to allocate once, and I think it should be possible in any way because I only have an unknown dimension (var is unknown, but 2 from the beginning I know).  
 Thank you!   
 
 
 (To answer the question directly.) You can declare as an indicator  
  int (* hashfunk) [2];   
 and assign it to one shot  
  hashfank = new int [var] [2];
