[i] indicates the position of the item in an array. If you're looping through the array, [i] will increment by 1 each time the loop is ran because of the i+=1 line. Therefore, the first time the loop is ran, i = 0, so student[i] will return the first item in the array. Then, i increments by 1 so that the next time the loop is ran, i = 1, and student[i] will return the 2nd item in the array.
