Find the Output: Opposite-direction counters

26Find the output of the following C code (assume #include <stdio.h> and that the code is inside int main(void)):
int i, j, sum = 0;
for (i = 1, j = 9; i < j; i += 2, j -= 2) {
    sum += i * j;
    printf("%d ", sum);
}
  • Option : A
  • Explanation : The two successful pairs are (1,9) and (3,7), producing cumulative sums 9 and 30. At (5,5), the condition fails.
