A variable in a program is a named placeholder that can contain any integer value. The statement z + e replaces the old value of the variable x with the result of evaluating the expression e. For example, if x initially contains 7 then the statement z + z +1 results in x containing 8. If the variables x, y and z initially contain the values 7, -2, and 8 respectively.
