change your for

for (i=1; i<=n; i++);

for

for (i=0; i<n; i++);

The indexes of array start at 0, then at array of size 5, the indexes will be:

[0], [1], [2], [3], [4]

That is, it starts at 0, and ends at size -1

Your current% of%, would try to access:

[1], [2], [3], [4], [5]

As there is no position 5, the error is returned:

"The index was outside the bounds of the array"
