Write a program, which will display the menu with 5 items. It will ask the use to give their choice. It will trap all possible errors and then print the result when correct input is provided before exiting the program.
Answer:
The program in Python is as follows:
print("Welcome to sorting program")
print("1. Title")
print("2. Rank")
print("3. Date")
print("4. Start")
print("5. Likes")
while(True):
choice = input("Enter a choice between 1 and 5 only: ")
if choice.isdigit() == True:
if(int(choice)>=1 and int(choice)<=5):
print("You entered valid choice", choice)
break;
else:
print("You have not entered a number between 1 and 5. Try again")
else:
print("You entered an invalid choice")
Explanation:
This prints the header
print("Welcome to sorting program")
The next 5 lines print the instructions
print("1. Title")
print("2. Rank")
print("3. Date")
print("4. Start")
print("5. Likes")
The loop is repeated until it is forcefully exited
while(True):
This prompts the user to enter a choice
choice = input("Enter a choice between 1 and 5 only: ")
This checks if the choice is a digit
if choice.isdigit() == True:
If yes, this checks if the choice is between 1 and 5 (inclusive)
if(int(choice)>=1 and int(choice)<=5):
If yes, this prints valid choice and the choice entered
print("You entered valid choice", choice)
The loop is exited
break;
If the choice is out of range
else:
This prints the error and tells the user to try again
print("You have not entered a number between 1 and 5. Try again")
If choice is not a digit
else:
This prints invalid choice
print("You entered an invalid choice")

Discuss five processes for analyzing a qualitative study
1. Prepare and organize your data.
Print out your transcripts, gather your notes, documents, or other materials. Mark the source, any demographics you may have collected, or any other information that will help you analyze your data.
2. Review and explore the data.
This will require you to read your data, probably several times, to get a sense of what it contains. You may want to keep notes about your thoughts, ideas, or any questions you have.
3. Create initial codes.
Use highlighters, notes in the margins, sticky pads, concept maps, or anything else that helps you to connect with your data. See the attached document that demonstrates how one might highlight key words and phrases as well as make notes in the margins to categorize the data:
4. Review those codes and revise or combine into themes.
Identify recurring themes, language, opinions, and beliefs.
5. Present themes in a cohesive manner.
Consider your audience, the purpose of the study, and what content should be included to best tell the story of your data.

If a program compiles fine, but it produces an incorrect result, then the program suffers from _______________.
If a program compiles fine, but it produces an incorrect result, then the program suffers from Logic Error.
What is program?A program has been the set of the instructions that the computer can follow that are written in a programming language. The size of the computer program affects the likelihood that an error may occur. To create an executable that a computer can run, a C program needs to be run through a C compiler. Programs are collections of instructions that a computer follows. Function is an ordered, reusable code unit.
When a program is syntactically sound but has a bug that is only discovered during program execution, it is said to have a runtime error. The Java compiler is unable to catch these errors during compilation; instead, the Java Virtual Machine (JVM) only notices them when the application is running. Runtime problems may occur when a website uses HTML code that is incompatible with a web browser's capabilities.
Therefore, if a program compiles fine, but it terminates abnormally at runtime, then the program suffers a runtime error.

Suppose there is exactly one packet switch between a sending user and a receiving user. The transmission rates between the sending user and the switch and between the switch and the receiving user are R1 and R2, respectively. Assuming that the switch uses store-and-forward packet switching, what is the
Answer: Hello your question lacks some data below is the missing data
what is the total end-to-end delay to send a packet of length L? (Ignore queuing, propagation, and processing delay) extend to N-1 packet switches interconnected by N links with rates R1, R2, …, RN
answer:
L/R1 + L/R2
Explanation:
The sending host will begin to transmit at to
At ( t1 = L/R1 ) the entire packet will be received at the router because at this time the sending host will complete the transmission process to the router.( No propagation delay )
At ( t2 = L/R2 ) the router completes transmission of the entire packet to the receiving host ( note : The transmission of the packet to the receiving host by the router starts at t1 hence No propagation delay is recorded. )
Which task is suitable for a manual process? Marvin’s software requires accurate, consistent testing. Yesenia's software requires, at most, one or two tests. Ahmad's software will be tested outside normal business hours. Braelyn’s software is subject to routine testing.
Answer:
The task that is suitable for a manual process is:
Yesenia's software requires, at most, one or two tests.
Explanation:
Manual testing of software involves a tester playing the end user's role to detect defects in the software. In such a test, the tester applies most of the features embedded in the software to ensure correct processing and output. Since Yesenia's software requires one or two tests, there is no need to automate the testing as a manual process will be economical.

Define a member method print_all() for class PetData. Make use of the base class' print_all() method. Sample output for the given program with inputs: 'Fluffy' 5 4444 Name: Fluffy Age: 5 ID: 4444
Answer and Explanation:
Using Javascript:
Class PetData{
Constructor(name, age, id){
this.name= name;
this.age =age;
this.id = id;
}
print_all(){
return this.name+""+this.age+""+this.id;
}
}
Here we have defined class PetData with its constructor which would initialize the object/instance of the class when called, example:
Var catData = new PetData(sisi, 1, 2333);
In this exercise we have to use the knowledge of computational language in python to write the following code:
The code can be found in the attached image.
That way, to find it more easily we have the code like:
Class PetData{
Constructor(name, age, id){
this.name= name;
this.age =age;
this.id = id;
}
print_all(){
return this.name+""+this.age+""+this.id;
}
}
Var catData = new PetData(sisi, 1, 2333);

Explain the function of different flags in the 8086
Answer:
A flag is a piece of fabric (most often rectangular or quadrilateral) with a distinctive design and colours. It is used as a symbol, a signalling device, or for decoration.8086 has 16-bit flag register, and there are 9 valid flag bits.The FLAGS register is the status register in Intel x86 microprocessors that contains the current state of the processor. This register is 16 bits wide. Its successors, the EFLAGS and RFLAGS registers, are 32 bits and 64 bits wide, respectively. The wider registers retain compatibility with their smaller predecessors.
Design and implement a program that manages coffees. First, implement an abstract class named Coffee. The Coffee class has three member variables: coffee type, price, and store name. The Coffee class has an abstract method name ingredient. Make sure to add all necessary setters and getters as well as other methods. The class Coffee implements an interface HowToMakeDrink. The interface has the following method: g
Answer:
interface HowToMakeDrink{
public void ingredient();
public void makeDrink();
}
class Coffee implements HowToMakeDrink{
String type;
double price;
String name;
public void ingredient(String ...items){
for (String i : items){
System.out.println('%s\n', i);
}
}
public makeDrink(){
System.out.println('Your '+ %s +' is ready', this.name);
}
public getType(){
return this.type;
}
public getPrice(){
return this.price;
}
public getName(){
return this.name;
}
public setType(String type){
this.type = type;
}
public setPrice(double price){
this.price = price;
}
public setName(String name-){
this.name = name;
}
}
Explanation:
The Coffee class is used to implement the HowToMakeDrink interface. The class uses the set and get methods to assign and retrieve the values of the class variables. It so implements the ingredient and makeDrink methods of the required interface.
