This is not about algorithms,but related to C programming.
How to implement sizeof operator?
macro for this
#define my_sizeof(a) (char*)(&a+1)-(char*)&a
this works fine of variables
int a;
printf("%d",my_sizeof(a)); //or even for user defined
structures
but it will not work for data types
like
printf("%d",my_sizeof(int));
so please get another solution.
function will be preferable.not macro
