{
m *= m;
return((10)*(m /= m));
}
int main()
{
int c = 9, *d = &c, e;
int &z = e;
e = BixFunction(c-- % 3 ? ++*d :(*d *= *d));

Please tell how c is 64?
It can be 64 only when both conditions are satisfied ie c--%3 is true as well as false.
My doubt is how can this line code can assume c to be 9 till ':' sign and 8 after (:)this sign.

c is post-decrement, so (c--%3) is evaluated as (c%3). This is equal to 0, so the false condition has to be executed.
But after the (c%3) is done, c is decremented (c--) , before the false condition is evaluated.

(*d *= *d) // This is where c=64.
m*= m; // m=4096.
Return ((10)*(m /= m)) ; //returns 10.
z = z + e/10; //here e=10, z=10. z+(e/10) = 11.
m*= m; // m=4096.
Return ((10)*(m /= m)) ; //returns 10.
z = z + e/10; //here e=10, z=10. z+(e/10) = 11.

int &z = e; <- this statement created a reference of e as z.
