Figure 1 - Question 11.
True or false? The program shown (incorrectly) in Listing 4 and correctly in Listing 5 requires the use of Ericson's multimedia library plus a jpg image file.
What is the meaning of the following two images?
This image was inserted here simply to insert some space between the questions and the answers to keep them from being visible on the screen at thesame time.
The image is also an example of the kinds of things that we do in my course titled ITSE 2321, Object-Oriented Programming.
This image was also inserted for the purpose of inserting space between the questions and the answers.
False. The program does require the use of Ericson's multimedia library but it does not require a jpg image file.
