You must change :

for (int i = 1; i <= 3; i++) // looping 3 times

to
for (int i = 0; i < 3; i++) // looping 3 times

But what the different? i think its the same equation.

No, they are ALMOST the same. Arrays start at zeroes, so when your loop goes from 1 to 3, you are out of bounds, since your array is s1[0], s1[1] and s1[2].
