size of a datatype without using sizeof

Question

I have a data type, say X, and I want to know its size without declaring a variable or pointer of that type and of course without using sizeof oper

Answer 1

Well, I am an amateur..but I tried out this problem and I got the right answer without using sizeof. Hope this helps.. I am trying to find the size of an integer.

int *a,*s, v=10;

a=&v;

s=a;

a++;

int intsize=(int)a-(int)s;

printf("%d",intsize);
