This code has a problem with the second op function. The return statement 'x?y' is not valid C++ syntax. I think the correct answer is B) It prints: 3,?0.3.

The output should be 3,0.3. The first call to op(i, j) will return the sum of i and j, which is 3. The second call to op(0, f) will return 0.3, since the first parameter is an integer and the second parameter is a float.

But the second function returns x?y, which means it will return 0.3 if x is not 0. So, I still think it's A)
