int main()
{
int x=4, y, z;
y = --x;
z = x--;
printf("%d, %d, %d\n", x, y, z);
return 0;
}
Options
A. 4, 3, 3
B. 4, 3, 2
C. 3, 3, 2
D. 2, 3, 3
Correct Answer
2, 3, 3
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".
