    Answer : Option D

    Explanation :

    Step 1: int x=4, y, z; here variable x, y, z are declared as an integer type and variable x is initialized to 4.
    Step 2: y = --x; becomes y = 3; because (--x) is pre-decrement operator.
    Step 3: z = x--; becomes z = 3;. In the next step variable x becomes 2, because (x--) is post-decrement operator.
    Step 4: printf("%d, %d, %d\n", x, y, z); Hence it prints "2, 3, 3".
