A variable in a program is a named placeholder that can contain any integer value. The statement te 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 I + +1 results in x containing 8. If the variables x,y and z initially contain the values 7, -2, and 8 respectively. What will be the value of y after the following statements are executed, in order, twice: I+I+2 - y y + 2 2 y y 0-19 35 29 21 None of the other answers are correct
