This is incrementing i, the counter for the loop:

i++;

This is a different statement, not at all the same as the above. It is adding the elements of the array themselves.

nums[i] += nums[i+1];

// Add to each number the number that follows in the array. Skip the last value in the array.
for (int i = 0; i < nums.length-1; i++) {
nums[i] += nums[i+1];why is it that when we use a for loop we ask it to do i++ ( which is i = i + 1)we still have to tell it nums[i] += nums[i+1]; isnt this the same thing. why do we have to tel processing twice that we want to add I++
