- 14. The nested conditional statement shown below has been written by an inexperienced C/C++ programmer. The behavior of the statement is not correctly represented by the formatting 97 a. What is the output of the statement if the variable n has the value 7 ? If n has the value 15 ? If n has the value -3 ? b. Correct the syntax of the statement so that the logic of the corrected statement corresponds to the formatting of the original statement. Also, replace the blank with an appropriate word or phrase. c. Correct the formatting of the (original) statement so that the new format reflects the logical behavior of the original statement. Also, replace the blank with an appropriate word or phrase.
- 15. The original statement is formatted in such a way that it appears that the "else" clause of the statement is the alternative to the "if (n < 10)" case, but in fact, the C or C++ compiler will treat the "else" clause as the alternative to the "if (n > 0)" clause. If n has the value 7 , the output will be "The number is positive". If n has the value 15 , then there will be no output. If n has the value -3 then the output will be "The number is ____________".

- 19. a. The output will be "less than 10". b. The output will be "greater than 15". c. The output will be "less than 10". d. There is no value for n that will cause the output to be "not interesting". That part of the code can never be executed!
- 20. 99 Rewrite the following code fragment so that it uses a "do...while..." loop to accomplish the same task. int n; cout << "Enter a non-negative integer: "; cin >> n; while (n < 0) { cout << "The integer you entered is negative." << endl; cout << "Enter a non-negative integer: "; cin >> n; }
- 22. 100 What is the output when the following code fragment is executed? int n, k = 5; n = (100 % k ? k + 1 : k - 1); cout << "n = " << n << " k = " << k << endl; NEXT
- 23. The output of the code fragment is as follows: n = 4 k = 5
