9. (TCO 9) Which of the following statements about testing are true? (Points : 5)
Black box test cases can be written as soon as the problem statement and program requirements are specified.
White box testing is typically done by the programmer as code is being developed.
Both black box and white box testing are commonly done to fully test a program.

{
case 5:
beta += 5;

} (Points : 5)
5+5+1+5 break =>16
16 (in reality, your compiler would not run this code since you used the case 5 label twice)
