MACRO CALL

 #define square(x) x*x

main()

{

int i;

i = 64/square(4);

printf("%d",i);

}

OUTPUT:

64

EXPLANATION:

The macro call square(4) will substituted by 4*4 so the expression becomes i = 64/4*4 . Since / and * has equal priority the expression will be evaluated as (64/4)*4 i.e. 16*4 = 64
