Hi!!!!!!!!!!!!!!!!!!!!

Please I want to know how to create a variable of 64 bits, and this variable must allow functionality for their shifting. Thanks for your help

Hi Banfa, Thanks for your help, I apreciated, well regarding one of my Question about permutation you told me that for the 64 bits variable I must declare it using the followin instruction, long long K, the thing is that Microsoft Visual c++ does not allow me to do it this way, so could you please tell me how to create this variable, so I can use shifting?

That is platform dependent so we can't help without knowing the platform.

[Banfa]

use

__int64

on microsoft (I may have the number of _ wrong check the help/header files).

So this is intended to be use in both plataform Linux and Windows. Thanks for your help

[Banfa]

on Linux use

long long

on Windows use

__int64

Oh and note

long long does not guarantee 64 bits in fact just that

sizeof(long long) >= sizeof(long)

it is just usual for it to be 64 bits.

And please reply to posts when talking about the same subject don't create new threads :-)
