Q.No.3 b. (Marks 3)
Explain why change is inevitable in complex systems and give examples (apart from prototyping and incremental delivery) of software process activities that help predict changes and make the software being developed more resilient to change.
Answer:
The change in complex systems can be explained according to the relationship of the environment where the system is implemented.
The system environment is dynamic, which consequently leads to adaptation to the system, which generates new requirements inherent to changes in business objectives and policies. Therefore, changing systems is necessary for tuning and usefulness so that the system correctly supports business requirements.
An example is the registration of the justification of the requirements, which is a process activity that supports changes in the system so that the reason for including a requirement is understood, which helps in future changes
Explanation:
Declare a 4 x 5 array called N.
Using for loops, build a 2D array that is 4 x 5. The array should have the following values in each row and column as shown in the output below:
1 2 3 4 5
1 2 3 4 5
1 2 3 4 5
1 2 3 4 5
Write a subprogram called printlt to print the values in N. This subprogram should take one parameter, an array, and print the values in the format shown in the output above.
Call the subprogram to print the current values in the array (pass the array N in the function call).
Use another set of for loops to replace the current values in array N so that they reflect the new output below. Call the subprogram again to print the current values in the array, again passing the array in the function call.

The XYZ daycare has installed a new high-tech system for keeping track of which children are under its supervision at any moment in time. Each parent of a child has a card with a unique ID, where the ID is some integer x. Every morning, the parent swipes the card at a card-reader when dropping their child off at the daycare. The system then adds x to an array of integers. In the evening, when the parent comes to pick up the child, the same card is swiped, and a second copy of x is added to the list. Each night at midnight, the array is wiped clean and reset to have zero elements. In this way, the daycare can quickly check every afternoon which children are yet to be picked up by their parents by picking out the array elements that occur precisely once. Unfortunately, at 4:55 pm on Thursday, April 20, 2017, the daycare realizes that somewhere in their daycare is precisely one child who is yet to be picked up. Can you help them determine the integer ID of this child

B. a diary
C. an email to a friend
D. a blog
Answer:
A. a brochure distributed to many people.
D. a blog.
Explanation:
Communication can be defined as a process which typically involves the transfer of information from one person (sender) to another (recipient), through the use of semiotics, symbols and signs that are mutually understood by both parties.
Generally, the linear model of communication comprises of four (4) main components and these are;
1. Sender (S): this is typically the source of information (message) or the originator of a message that is being sent to a receiver. Thus, they are simply the producer of a message.
2. Channel (C): this is the medium used by the sender for the dissemination or transmission of the message to the recipient. For example, telephone, television, radio, newspapers, billboards etc.
3. Message (M): this is the information or data that is being sent to a recipient by a sender. It could be in the form of a video, audio, text message etc.
4. Receiver (R): this is typically the destination of information (message) or the recipient of a message that is being sent from a sender.
Hence, the following are forms of media (communication channel);
I. A brochure distributed to many people. It comprises of printed textual informations used mainly for promotional purposes.
II. A blog. It is an online website that contains both textual and multimedia messages, especially as a news platform.

Course Project Part 4: Conducting the Experiment and Recording Data
After much preparation, you are finally ready to begin conducting your experiment. Due to all the hard work you put into your literature review and planning your procedures, the steps that you need to take to conduct your experiment successfully have already been set. While you conduct your experiment, you will need to keep a daily journal where you record the activities you undertake that are relevant to the experiment and also where you record any data that you collect. This is your experiment log and serves as a record of your work while also allowing you to make a record of any changes or modifications you may need to make during the experiment.
Conducting the Experiment and Keeping an Experiment Journal
Following the procedure that you established in the previous part of this project, set up your experiment and begin running it. Every day while your experiment is running you will make an entry in your journal. Record what activities you completed (refer to your outlined procedure to make sure you are following the procedure that you established), any modifications that had to be made to your set up or procedure, and any observations or data you collect. Even on days when you do not collect data (depending on your experiment, there may not be data collection every day), make an entry in your journal. Each journal entry should be clearly labeled with the date on which it was entered. You do not need to type up all your entries, but make sure that your journal entries are neatly written, as they will be evaluated by your instructor.
Depending on the topic and design of your experiment, the period of time during which you conduct and record your experiment may range from one to several weeks. In consultation with your instructor, you will establish a timeline for the evaluation of your journal. If you are running a shorter experiment, your journal may be evaluated several times over the course of one or two weeks. If your experiment takes longer to complete, you may have a weekly review over the course of a month. Follow the guidelines provided by your instructor.
Collecting Data
All experiments generate data. This data allows the scientist to evaluate the success of the experiment and make interpretations about the results generated by the investigation. When you record your data, you must collect it as consistently as possible. Returning to the plant experiment, it would be best to measure the plants on a set schedule. For example, you might choose to measure the plants every Thursday at 3 pm. It is important to measure the plants at the same time each week so that the difference in growth you might observe is a reflection of the experimental condition, not simply longer growing time. Additionally, it is important to use the same instruments to collect data. The plants should be measured with the same ruler or measuring tape each time. This helps reduce any error or bias that might be introduced by using different instruments to make measurements. Whatever measurements or data you collect, do so in a consistent manner. Use the same instruments, the same scales, and record the data in a standardized manner. It is also a good idea to record your experiment using photographs. This will help you later during analysis and provides information for others who might be interested in recreating your experiment. Record your data in your experiment journal, where it will be reviewed by your teacher on an on-going basis. Submit your journal to your instructor according to the schedule you have established together.

You plan to make a delicious meal and want to take the money you need to buy the ingredients. Fortunately you know in advance the price per pound of each ingredient as well as the exact amount you need. The program should read in the number of ingredients (up to a maximum of 10 ingredients), then for each ingredient the price per pound. Finally your program should read the weight necessary for the recipe (for each ingredient in the same order). Your program should calculate the total cost of these purchases, then display it with 6 decimal places.
Example There are 4 ingredients and they all have a different price per pound: 9.90, 5.50, 12.0, and 15.0. You must take 0.25 lbs of the first, 1.5 lbs of the second, 0.3 lbs of the third and 1 lb of the fourth. It will cost exactly $29.325000.
Answer:
In Python:
prices = []
pounds = []
print("Enter 0 to stop input")
for i in range(10):
pr = float(input("P rice: "+str(i+1)+": "))
pd = float(input("Pound: "+str(i+1)+": "))
if pr != 0 and pd != 0:
prices.append(pr)
pounds.append(pd)
else:
break
amount = 0
for i in range(len(pounds)):
amount+= (pounds[i]*prices[i])
print("Amount: $",amount)
Explanation:
These initialize the prices and pounds lists
prices = []
pounds = []
This prompts the user to enter up to 10 items of press 0 to quit
print("Enter 0 to stop input")
This iterates through all inputs
for i in range(10):
This gets the price of each item
pr = float(input("P rice: "+str(i+1)+": "))
This gets the pound of each item
pd = float(input("Pound: "+str(i+1)+": "))
If price and pound are not 0
if pr != 0 and pd != 0:
The inputs are appended to their respective lists
prices.append(pr)
pounds.append(pd)
If otherwise, the loop is exited
else:
break
This initializes total to 0
amount = 0
This iterates through all inputs
for i in range(len(pounds)):
This multiplies each pound and each price and sum them up
amount+= (pounds[i]*prices[i])
The total is then printed
print("Amount: $",amount)
