The difference between a Variable and a Constant is that a variable varies with other numbers and a constant remains as the same number and it does not change at all. Moreover, a Constant is a number that cannot change. It cannot change because it is not a variable. A variable is a vary. A vary is the difference or change. Finally, this is the difference between a Variable and Constant.
