Answer:

4 and 50

Explanation:

To answer the question above, we are to first of all consider the size of union will be the max size of datatype in union data. I.E.

sizeof(int *) is 4 bytes

so, sizeof(U) = sizeof(temp) is 4

and we saved 50 in temp.i1. so, 50 we can access 50 from temp.i2 as well

so, output is 4 and 50
