Question 1
Given the following composite condition (a>=0 && b==3) || c>b
Generate a set of test cases (just the input values for a, b, and c) that you need to have 100% MC/DC coverage.
Question 2
Given the following fragment of code:
int tent=0, x=92, num; cout<<"Guess the number :"; cin>>num; while ((tent<5)&&(num!=x)) {
tent++; if (num>x)
cout<<"Smaller\n"; else
if (num
cout<<"Bigger\n"; else
cout<<”You won!\n” cout<<"Guess the number :"; cin>>num; }
(1) Build the corresponding control flow graph.
(2) Generate the test cases for reaching (if possible) 100% coverage with the statement
coverage criterion.
(3) Does the test suite created in (2) guarantee also 100% branch coverage? If not,
modify/augment your test suite in order to reach (if possible) 100% coverage with the branch coverage criterion.
(4) Which is the cyclomatic number?
(5) How many boundary paths you would need to cover to guarantee 100% coverage with the boundary/interior path coverage criterion? Are those paths coverable?
Homework Answers
1.) Here we need 5 tests to fulfill 100% MC/DC coverage. Below are those cases.
| a>=0 | b==3 | c>b | Decision |
| TRUE | FALSE | TRUE | TRUE |
| TRUE | FALSE | FALSE | FALSE |
| TRUE | TRUE | TRUE | |
| FALSE | TRUE | TRUE | |
| FALSE | FALSE | FALSE |

Project 1 - Wallet Following the class diagram shown below, create the class Wallet. A Wallet represents a carrier of bills and coins. You use your wallet to pay for things, which reduces the balance held inside. When you visit an ATM, you can fill it back up with cash again. A sample driver for this class is shown below. You should probably make a more thorough driver to test your class better. I will have my own driver which...

1. Please provide a C++ program which faithfully reads a list of non-negative integer scores, ultimately terminating the list reading when the sentinel value (lets use -9999) is entered. The program should then correctly report the number of non-negative scores entered and the arithmetic mean (average) of those scores 2. Demonstrate your programs behavior in response to errors on input (that is, show that it faithfully rejects improper input such as alphabetic characters, decimal points, and commas). Here are some...

I've posted 3 classes after the instruction that were given at start You will implement and test a PriorityQueue class, where the items of the priority queue are stored on a linked list. The material from Ch1 ~ 8 of the textbook can help you tremendously. You can get a lot of good information about implementing this assignment from chapter 8. There are couple notes about this assignment. 1. Using structure Node with a pointer point to Node structure to...
