index += 1
Loop
a. The test variable should not be changed inside a Do loop.
b. The test condition will never be true.
c. This is an infinite loop.
d. Nothing
2. In analyzing the solution to a program, you conclude that you want to construct a loop so that the loop terminates either when (a < 12) or when (b = 16). Using a Do loop, the test condition should be:
a. Do While (a > 12) Or (b < > 16)
b. Do While (a >= 12) Or (b < > 16)
c. Do While (a < 12) Or (b < > 16)
d. Do While (a >= 12) And (b < > 16)
3. When Visual Basic
