Explain the difference between a pre-increment and a post-increment operator.

a pre-increment increases i and then return i, and a post-increment makes a copy, increases i, and returns the copy of the old value.

2. What are arguments? Where do arguments appear in a C program overall?

3. What other term is sometimes used for an argument?

4. When constructing functions, why would you choose a pass by value parameter rather than just using a global constant?

5. What is a ternary operator? When should it be used and when should it be avoided?

6. What does the hand trace of a C program validate?

7. Why is short-circuiting the evaluation of an expression in C a good thing?

8. Explain in 30 words or less the primary difference between a sentinel-controlled loop and a counter- controlled loop.

9. Given the following code, identify which is preferable and explain your answer.

10. Besides initialization, repetition test, and update, can you think of any other things that would be convenient to have in an iterator header?

11. With a counting for loop, is it ever appropriate to change the loop control variable in the body of the loop? Justify your answer.

12. Explain in 30 words or less the primary difference between a flag and a sentinel value?

13. Rather than having the user enter guesses, how could this program be changed to have the program make guesses until the calculation is within 0.1% of the desired channel flow?

15. What is printed when C executes the following statements? Why do you think that happens? Explain.

16. How is a function in C, other than main( ), executed?

17. We say that if a new problem is an extension of a previous one, we should modify the previous program instead of starting a new program from scratch. Explain why this is so. Give examples where it might be desirable and instances where it might be undesirable.

18. What is meant by a compound statement? Where might you use one?

19. Briefly explain what pseudocode is and where you might use it.

20. If a proper debugger isn't available on the system where you're programming, how can you best work around this shortcoming?
