(Hint: Think in terms of what has been taught in the lectures and notes. You do not need to research what happens at the hardware level as that is outside the scope of the unit.)What actions does the computer perform when it executes the statement c = e + c; from Code Sample 4?How would the value of variable i change in the statement i = i + 1;?
