Question 12
Back to Exercise
What is the output of the following C program?
#include <stdio.h>
int main(void) {
int a[] = {2, 4, 6, 8};
int sum = 0;
for (int *p = a; p < a + 4; p += 2)
sum += *p;
printf("%d\n", sum);
return 0;
}- A 20
- B 8 Correct
- C 12
- D 6
Correct Answer: Option B
p visits a[0] and a[2] only, because it moves 2 elements each time: 2 + 6 = 8. The next step would be a + 4, which ends the loop.
