Wrong output in printing values using for loop in C

I wrote a simple C program to print all the multiples of 3 but there is some error during runtime my code is:

#include <stdio.h>

void main(void) {
    int i, x;
    for(i = 1; i < 1000; i++) {
        x = i % 3;
        if(x == 0) {
            printf("%d\n", i);
        }
     }
}

the problem is that if I enter numbers greater than 891 till 1000 in the loop the output is starting from 6 instead of 3 and if i write the code as above than the output is starting from 114. for the values less than or equal to 891 it is showing the correct output.

Make sure you can view all output:

reuts@reuts-K53SD:~/ccccc$ cat mmph.c && gcc mmph.c
#include<stdio.h>
main(){

    int i,x;
    for(i=1;i<1000;i++)
    {
        x=i%3;

        if(x==0){
            printf("%d\n",i);

        }
    }
}
reuts@reuts-K53SD:~/ccccc$ ./a.out | egrep "^3$|999"
3
999

As you can see, this works. Your output is probably truncated.
