Which of the following need to be assessed during unit testing?
A) algorithmic performance
B) code stability
C) error handling
D) execution paths
E) both c and d
Error handling & execution paths whether any of the following should be evaluated in the testing phase, and further discussion can be defined as follows:
Error handling relates to routines in programming that respond to unexpected inputs or conditions. It is also the process for dealing with the possibility of loss. The lucidity of error messages and the options provided to the users regarding problem resolution assess the quality of these procedures. It's significant because it makes life simpler for end-users to use the code appropriately. The execution route is a potential flow of command in a program. During symbolic execution, each execution path keeps and changes the mapping from variables to symbolic expressions. Sequence expressions including if cause an execution path to split into two distinct test steps.Therefore, the answer is "Option E".

C++ code-- Factorial Recursion
Write code to complete PrintFactorial()'s recursive case. Sample output if userVal is 5:
5! = 5 * 4 * 3 * 2 * 1 = 120
#include
using namespace std;
void PrintFactorial(int factCounter, int factValue){
int nextCounter = 0;
int nextValue = 0;
if (factCounter == 0) { // Base case: 0! = 1
cout << "1" << endl;
}
else if (factCounter == 1) { // Base case: Print 1 and result
cout << factCounter << " = " << factValue << endl;
}
else { // Recursive case
cout << factCounter << " * ";
nextCounter = factCounter - 1;
nextValue = nextCounter * factValue;
}
}
int main() {
int userVal = 0;
userVal = 5;
cout << userVal << "! = ";
PrintFactorial(userVal, userVal);
return 0;
}
Answer:
void PrintFactorial(int factCounter, int factValue){
int nextCounter = 0;
int nextValue = 0;
if (factCounter == 0) { // Base case: 0! = 1
cout << "1" << endl;
}
else if (factCounter == 1) { // Base case: Print 1 and result
cout << factCounter << " = " << factValue << endl;
}
else { // Recursive case
cout << factCounter << " * ";
nextCounter = factCounter - 1;
nextValue = nextCounter * factValue;
printFactorial(nextCounter, nextValue);
}
}
Explanation:
The only things that is left is calling the recursive function in the else statement. It is the bolded command on the answer.
factCounter is the value we are multiplying. In the function, it is nextCounter. So for 5, it is 5, then 4, then 3, until 0...
factValue is the value of the factorial. In the function, it is nextValue So it is 5, then 5*4 = 20, then 5*4*3 = 60, then...
void PrintFactorial(int factCounter, int factValue){
int nextCounter = 0;
int nextValue = 0;
if (factCounter == 0) { // Base case: 0! = 1
cout << "1" << endl;
}
else if (factCounter == 1) { // Base case: Print 1 and result
cout << factCounter << " = " << factValue << endl;
}
else { // Recursive case
cout << factCounter << " * ";
nextCounter = factCounter - 1;
nextValue = nextCounter * factValue;
printFactorial(nextCounter, nextValue);
}
}

In a ______ connection, two and only two devices are connected by a dedicated link.
A) multipoint
B) point-to-point
C) (a) and (b)
D) none of the above
In a point-to-point connection, two and only two devices are connected by a dedicated link. Thus, option B is correct.
What is devices?A piece of machinery, apparatus, or system created with a specific function in mind. devices like cell phones as well as other electronics. Devices include any computer, mobile phone, phone, video recorder, recorder, or other electronic gadgets which can be used to create, store, or transport media in the form of digital communications.
Exclusive connectivity between devices connected is provided through a P2P connection. These two devices are the only ones allowed to transmit at the complete capability of a link.
A unique link that links two network components is known as a point-to-point link. These two machines transmit data using the ’s of such a link.
Therefore, option B is the correct option.

The correct answer is B) point-to-point. This connection type refers to a dedicated link between two and only two devices, providing a direct communication path.
Explanation:
In a point-to-point connection, two and only two devices are connected by a dedicated link. The correct answer to this question is B) point-to-point. A point-to-point connection is a direct communication path between two devices where they are uniquely connected with each other.

Frequency of failure and network recovery time after a failure are measures of the _______ of a network.
A) Performance
B) Reliability
C) Security
D) Feasibility
Final answer:
The frequency of failure and network recovery time after a failure are measures of the reliability of a network, reflecting its stability and how quickly it can resume normal operations after downtime.
Explanation:
The frequency of failure and network recovery time after a failure are measures of the reliability of a network. When assessing reliability, it is important to consider how consistent a network is in terms of its uptime and its ability to maintain functionality over time.
Reliability is a key factor in network design and operation because it quantifies the likelihood of a system operating without failure for a certain period of time. In a network context, reliability encompasses not only the stability of the network but also the speed at which it can recover from issues, including errors, faults, and failures. An unreliable network might experience frequent downtimes or take a long time to recover from disruptions, negatively affecting the users and potentially leading to loss of data or service.
Let's consider another scenario outside of networking for a broader understanding of reliability. In research, reliability refers to the measure of a study's consistency that considers how likely results are to be replicated if a study is reproduced. Similar to network reliability, this also focuses on the predictability and stability of outcomes.
Reliability should not be confused with feasibility or performance, which deal with different aspects of network or system attributes.
The frequency of failure and network recovery time after a failure are measures of the reliability of a network, indicating the system's consistency and likelihood of uninterrupted performance.
Explanation:The frequency of failure and network recovery time after a failure are measures of the reliability of a network. Reliability in this context refers to the likelihood that a system will perform as expected over a given period. It is a measure of consistency, indicating how likely it is for the network's performance to be replicated consistently without failures. A reliable network typically experiences less downtime and is able to recover quickly from interruptions, thus ensuring consistent connectivity and service availability.
A java ____ is a program written in the java programming language that can be included in a web page.
Answer:
Java Applets are used to include java programs on web page.
Explanation:
Java Applets are small java programs that can be run on any browser with appropriate Java Plug-in and displays applet as a section of web page.
How to Create Applet
Create an applet class by extending it with JApplet and add a paint method in it. for example
import java.awt.*;
import javax.swing.*;
public class HelloWorld extends JApplet {
public void paint(Graphics graphic)
{
super.paint(graphic);
}
}
The above code will create an applet and super.paint(graphic) method will draw the applet for you.
In order to display "Hello World" string in applet. you just need to add the following line after super.paint(graphic); method.
graphic.drawString("Hello World" , 20, 20);
Run Code
Click on Run Button and you will able to see the applet in applet viewer window.
