		12. What is printed by the following program fragment? (All variables are of type int.)



		for (row = 1; row <= 10; row++) { for (col = 1; col <= 10 - row; col++) cout << ; for (col = 1; col <= 2row - 1; col++) cout << ; for (col = 1; col <= 10 - row; col++) cout << *; cout << endl; }



		13. A break statement located inside a Switch statement that is within a While loop causes control to exit the loop immediately. (True or False?)



		14. Given the For statement



		for (count = 3; count <= 20; count++) cout << Hello << endl;



		which one of the following invariants for count is correct just prior to the loop test?



		a. 1< count < 20 b. 3< count < 20 c. 2< count < 20 d. 3< count < 21 e. 3< count < 21



		Programming Warm-Up Exercises



		1. Write a Switch statement that does the following:



		If the value of grade is A, add 4 to sum B, add 3 to sum C, add 2 to sum D, add 1 to sum F, print Student is on probation



		2. Modify the code for Exercise 1 so that an error message is printed if grade does not equal one of the five possible grades.



		3. Rewrite the Day function of Chapter 8 (pages 406408), replacing the If-Then-Else-If structure with a Switch statement.



		4. Write a program segment that reads and sums until it has summed 10 data values or until a negative value is read, whichever comes first. Use a Do-While loop for your solution.



		5. Rewrite the following code segment using a Do-While loop instead of a While loop.



		cout << Enter 1, 2, or 3: ; cin >> response;
