Anyone can tell me what is wrong with that code please?

Question

#include<stdio.h>

int main(void)
{
int a[9];
int i;
printf("input:\n");
for (i = 0; i <= 8; i++)
{
scanf("%d", &a[i]);
}
for (i = 0; i <= 8; i = i + 3)
{
printf("output:\n");
printf("%d , %d, %d \n", a[i], a[i + 1], a[i + 2]);

return 0;
}

}

Answer 1

You are returning 0 inside the second loop, so it is terminated in the first run.

Answer 2

Write a program that reads nine integers and prints them three in a line separated by commas as shown below.

Input:
10 31 2 73 24 65 6 87 18
Output
10, 31, 2
73, 24, 65
6, 87, 18

Answer 3
