for-loop

Hi,

I am stuck with this mystery regarding for loop.

    int abc[3], i, j;
    for(j=0; j<3; j++);
    printf("%d\n", j);
    abc[j] = abc[j] + 3;
    printf("%d \n", j);


Output: 

3
6

Output should have been 3,3 as I've not changed value of j.

Adding 3 to the jth value of abc has resulted in change of value of j by 3. This happens only while exiting from a for loop and then trying to change the value of abc[j].

Maybe I am missing something pretty obvious. Any help would be much appreciated.

I had learnt by reading your great answers here, that it is not good practice deleting items from within a foreach loop, as it is (and I quote) "Sawing off the branch you're sitting on".
