Re: How to identity processor architecture

[prabhu <prabhum@xxxxxxxxxxxxx>]

Hi Enrico,

I am not sure.

No, because 32bit code will tell the datatype size and i think pointer variable depends on architecture.
So 64 bit processor needs 64 address line to point the data location. So pointer variable needs to be 8 byte.

please correct me if i am worng.

Thanks,
Prabhu

What if one is compiling 32bit code on a 64bit processor? Would 4 be an acceptable result to you in that case?

Hi Dear,

I just wanna to know my processor architecture(32bit or 64 bit) through
c programming.

According to me the sizeof of pointer will give the result. Like below
coding.

int main()
{
   int *ptr;
   printf("%d",sizeof(ptr));
}

Please correct me if i am wrong...

Any suggestion or help would be appreciated.

Thanks,
Prabhu
