1. REVIEW FOR LESSON 4 Variables

2. 1. W HAT IS THE BEST DEFINITION FOR A VARIABLE ? A. A number B. A letter that stands for any number C. A placeholder for something else D. A permanent constant for a number or word

3. 2. W HAT DOES THE TRACE STATEMENT WRITE TO THE OUTPUT WINDOW ? VAR N :N UMBER = 10; VAR T :N UMBER = 25; TRACE ( N + T ); A. N+T B. 35 C. 10 D. 25

4. 3. W HAT DOES THE TRACE STATEMENT WRITE TO THE OUTPUT WINDOW ? VAR N = 25-3+2; TRACE ( N ); A. Nothing because there is an error – n can only be one number B. n C. 20 D. 24

5. 4. T HE B OX M OVIE C LIP HAS BEEN EXPORTED FOR A CTION S CRIPT WITH THE CLASS NAME B OX. W HAT IS THE CORRECT WAY TO ADD AN INSTANCE OF THE B OX MOVIE CLIP TO THE STAGE JUST USING A CTION S CRIPT ? A.var myMovie:MovieClip; addChild(myMovie); B. addChild(Box); C. var myBox:MovieClip; myBox = new Box(); addChild(Box); D. var myMovie:MovieClip; myMovie = new Box(); addChild(myMovie);

6. 5. T HE EQUAL SIGN ( = ) CAN MEAN MORE THAN JUST ‘ BOTH SIDES OF THIS EQUATION ARE EQUAL.’ I N PROGRAMMING IT CAN MEAN AN ASSIGNMENT IS BEING MADE. K NOWING THIS, CAN THE CODE BELOW WORK : VAR T :N UMBER = 5; T = T + 2; TRACE ( T ); A. No, because t equals 5 and 5 does not equal 7 B. Yes, because first you evaluate the code on the right then put it into the on the left C. No, because 5 = 5. It can’t equal a different number. D. I’m confused.
