Textbook Question
Chapter 16.1, Problem 2STE
What would be the output produced by the code in Self-Test Exercise 1 if we make the following change? Change the line
| int waitTime = 46; |
to
| int waitTime = 12; |
1. What output is produced by the following code?
| int waitTime = 46; try { cout << "Try block entered.\n"; if (waitTime > 30) throw waitTime; cout << "Leaving try block.\n"; } catch(int thrownValue) { cout << "Exception thrown with\n" << "waitTime equal to " << thrownValue << endl; } cout << "After catch block." << endl; |

ACTIVITY
Type two statements that use rand() to print 2 random integers between (and including) 100 and 149. End with a newline. Ex:
101
133
3.8.3: Fixed range of random numbers.
Note: For this activity, using one statement may yield different output (due to the compiler calling rand() in a different order). Use
two statements for this activity. Also, srand() has already been called; do not call srand() again.

The following PThreads code is written for book reservation in a library. Each student checks if the book is free. If it
was free they will reserve it with their own ID and the book becomes unavailable to the rest.
a. Can you identify the problem with this code? Explain the condition that the code may fail.
b. Rewrite the code (just a few lines of code) to solve the problem.
//PThreads code here

- Auto-graded programming assignments may use a Unit test to test small parts of a program. Unlike a Compare output test, which evaluates your program's output for specific input values, a Unit test evaluates individual methods to determines if each method: is named correctly and has the correct parameters and return type • calculates and returns the correct value (or prints the correct output) This example lab uses multiple unit tests to test the kilo ToPounds() function. Complete a program that takes a weight in kilograms as input, converts the weight to pounds, and then outputs the weight in pounds. 1 kilogram = 2.204 pounds (lbs). Ex: If the input is: 10 the output is: 22.040000000000003 lbs Note: Your program must define the method public static double kiloToPounds (double kilos) The program below has an error in the kilo ToPounds() method. 1.
