A constant never changes.  Its value is constant, which is a big part of the reason why it's called a "constant".  " 42 " is constant.  It doesn't depend on anything.

A variable can change.  Its value varies, and that's why it's described as "variable".  ' x ' is a variable. Its value depends on what ' x ' is.
