Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

26. OOD also takes advantage of ________ relationships where new classes of objects are derived by absorbing characteristics of existing classes - then adding unique characteristics of their own.






27. The escape sequence ___ when output with cout and the stream insertion operator - causes the cursor to position to the beginning of the next line on the screen.
