Answer:
D. The object in a program is called a class.
Explanation:
Java is a object oriented and class-based programming language. It was developed by Sun Microsystems on the 23rd of May, 1995. Java was designed by a software engineer called James Gosling and it is originally owned by Oracle.
In object-oriented programming (OOP) language, an object class represents the superclass of every other classes when using a programming language such as Java. The superclass is more or less like a general class in an inheritance hierarchy. Thus, a subclass can inherit the variables or methods of the superclass.
Basically, all instance variables that have been used or declared in any superclass would be present in its subclass object.
Hence, the relationship between an object and class in an OOP program is that the object in a program is called a class.
For example, if you declare a class named dog, the objects would include barking, color, size, breed, age, etc. because they are an instance of a class and as such would execute a method defined in the class.
In this programming assignment, you will write a simple program in C that outputs one string. This assignment is mainly to help you get accustomed to submitting your programming assignments here in zyBooks. Write a C program using vim that does the following. Ask for an integer input from the user. Do not print any prompt for input. If the number is divisible by 3, print the message CS If the number is divisible by 5, print the message 1714 If the number is divisible by both 3
Answer:
In C:
#include <stdio.h>
int main() {
int mynum;
scanf("%d", &mynum);
if(mynum%3 == 0 && mynum%5 != 0){
printf("CS"); }
else if(mynum%5 == 0 && mynum%3 != 0){
printf("1714"); }
else if(mynum%3 == 0 && mynum%5 == 0){
printf("CS1714"); }
else {
printf("ERROR"); }
return 0;
}
Explanation:
This declares mynum as integer
int mynum;
This gets user input
scanf("%d", &mynum);
This condition checks if mynum is divided by 3. It prints CS, if true
if(mynum%3 == 0 && mynum%5 != 0){
printf("CS"); }
This condition checks if mynum is divided by 5. It prints 1714, if true
else if(mynum%5 == 0 && mynum%3 != 0){
printf("1714"); }
This condition checks if mynum is divided by 3 and 5. It prints CS1714, if true
else if(mynum%3 == 0 && mynum%5 == 0){
printf("CS1714"); }
This condition checks if num cannot be divided by 3 and 5. It prints ERROR, if true
else {
printf("ERROR"); }
Consider a disk that rotates at 3600 rpm. The seek time to move the head between adjacent tracks is 2 ms. There are 32 sectors per track, which are stored in linear order from sector 0 through sector 31. The head sees the sectors in ascending order. Assume the read/write head is positioned at the start of sector 1 on track 8. There is a main memory buffer large enough to hold an entire track. Data is transferred between disk locations by reading from the source track into the main memory buffer and then writing the data from the buffer to the target track. a. How long will it take to transfer sector 1 on track 8 to sector 1 on track 9
Answer:
19.71 ms
Explanation:
The disk rotates at 3600 rpm, hence the time for one revolution = 60 / 3600 rpm = 16.67 ms.
Hence time to read or write on a sector = time for one revolution / number of sectors per track = 16.67 ms / 32 sectors = 0.52 ms
Head movement time from track 8 to track 9 = seek time = 2 ms
rotation time to head up sector 1 on track 8 to sector 1 on track 9 = 16.67 * 31/32 = 16.15 ms
The total time = sector read time +head movement time + rotational delay + sector write time = 0.52 ms + 2 ms + 16.15 ms + 0.52 ms = 19.19 ms
It will take 19.19 ms to transfer sector 1 on track 8 to sector 1 on track 9
The given parameters are:
[tex]d_r = 3600 rpm[/tex] --- the disk rotation
[tex]s=32[/tex] --- the sectors in a track
Calculate the time (t) to complete one revolution
[tex]t = \frac{60}{d_r}[/tex]
[tex]t = \frac{60}{3600}[/tex]
[tex]t = \frac{1}{6}[/tex]
So, the time to read/write to a sector is:
[tex]T = \frac{t}{s}[/tex]
This gives
[tex]T = \frac{1/6}{32}[/tex]
[tex]T = \frac{1}{192}[/tex]
Convert to ms
[tex]T = \frac{100}{192}[/tex]
[tex]T = 0.52ms[/tex]
Next, calculate the rotation time to head up sector 1 on track 8 to sector 1 on track 9
This is calculated as:
[tex]r_t = t \times \frac{s-1}{s}[/tex]
So, we have:
[tex]r_t = \frac 16 \times \frac{32-1}{32}[/tex]
[tex]r_t = \frac 16 \times \frac{31}{32}[/tex]
[tex]r_t = 0.1615[/tex]
Convert to ms
[tex]r_t = 0.1615 \times 100[/tex]
[tex]r_t = 16.15[/tex]
So, the required time to transfer sectors is:
Time = 2 * Time to read/write to a sector + Seek time + Rotation time
This gives
[tex]Time = 2 \times 0.52 + 2 + 16.15[/tex]
[tex]Time = 19.19[/tex]
Hence, it will take 19.19 ms to transfer sector 1 on track 8 to sector 1 on track 9

In the following code segment, assume that the ArrayList numList has been properly declared and initialized to contain the Integer values [1, 2, 2, 3]. The code segment is intended to insert the Integer value val in numList so that numList will remain in ascending order. The code segment does not work as intended in all cases.
int index = 0;
while (val > numList.get(index))
{
index++;
}
numList.add(index, val);
For which of the following values of val will the code segment not work as intended?
a. 0
b. 1
c. 2
d. 3
e. 4
Answer:
e. 4
Explanation:
The code segment will not work as intended if the value of the variable val is 4. This is because the while loop is comparing the value of the variable val to the value of each element within the numList. Since there is no element that is bigger than or equal to the number 4, this means that if the variable val is given the value of 4 it will become an infinite loop. This would cause the program to crash and not work as intended.
The program illustrates the use of while loops.
The code segment will not work as intended when the value of val is 4
LoopsLoops are used to perform repeated operations
The programFrom the program, the while loop is repeated under the following condition:
val > numList.get(index)
This means that:
The loop is repeated as long as val has a value greater than the index of numList (i.e. 3)
From the list of options, 4 is greater than 3.
Hence, the code segment will not work as intended when the value of val is 4

The cafeteria offers a discount card for sale that entitles you, during a certain period, to a free meal whenever you have bought a given number of meals at the regular price. The exact details of the offer change from time to time. Describe an algorithm that lets you determine whether a particular offer is a good buy. What other inputs do you need
Answer:
Explanation:
The algorithm can be described as follows
The first process is to ensure that the constraints for the time at which the offers begin is well defined.
TIME1 = 14:00
TIME2 = 16:00
TIME3 = 18:00
Then, decide the final number of meal following the free meal that has been offered.
NUMBER_OF_MEALS=4;
Then; decide the prices attached to the meal at regular times.
PRICE = 200;
At regular mode, decide the prices attached to the meal and as well as when the offer time commences.
PRICE_OFFER = 160;
Then ask the client(i.e the user) to put in the value required for the number of meals they desire to order.
Input values in n
Suppose (the value exceeds 8)
Then proceed to enquire from the client if they wish to go for the offer.
If not, use the regular price for the order.
Assume the client asks if the offer is a good one to bid for.
You are to show then the analysis of the calculation.
regular = 8 × PRICE
offer = 8 × PRICE_OFFER
profit = regular - offer
Finally, show the profit to the client which will let them know if it is good to bid for it or not.

Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.
There are four (4) major types of database in a data warehouse and these are;
1. Multistage database: used for concise as well as detailed historical data. It provides summarized data which can be used by an employee for short-term decision making.
2. Stationary database: used where access to data is rare i.e business firms who do not access data frequently. In order to use this database, the users must have an access to metadata store and thus, directly having access to the data on a source system.
3. Virtual database: used for accessing data in diverse applications using middleware. This type of database is dependent on having access to information on various databases.
4. Distributed database: used by an organization that runs several businesses. Therefore, this type of database are usually located or situated in various geographical regions.
You've created a new programming language, and now you've decided to add hashmap support to it. Actually you are quite disappointed that in common programming languages it's impossible to add a number to all hashmap keys, or all its values. So you've decided to take matters into your own hands and implement your own hashmap in your new language that has the following operations:
insert x y - insert an object with key x and value y.
get x - return the value of an object with key x.
addToKey x - add x to all keys in map.
addToValue y - add y to all values in map.
To test out your new hashmap, you have a list of queries in the form of two arrays: queryTypes contains the names of the methods to be called (eg: insert, get, etc), and queries contains the arguments for those methods (the x and y values).
Your task is to implement this hashmap, apply the given queries, and to find the sum of all the results for get operations.
Example
For queryType = ["insert", "insert", "addToValue", "addToKey", "get"] and query = [[1, 2], [2, 3], [2], [1], [3]], the output should be hashMap(queryType, query) = 5.
The hashmap looks like this after each query:
1 query: {1: 2}
2 query: {1: 2, 2: 3}
3 query: {1: 4, 2: 5}
4 query: {2: 4, 3: 5}
5 query: answer is 5
The result of the last get query for 3 is 5 in the resulting hashmap.
For queryType = ["insert", "addToValue", "get", "insert", "addToKey", "addToValue", "get"] and query = [[1, 2], [2], [1], [2, 3], [1], [-1], [3]], the output should be hashMap(queryType, query) = 6.
The hashmap looks like this after each query:
1 query: {1: 2}
2 query: {1: 4}
3 query: answer is 4
4 query: {1: 4, 2: 3}
5 query: {2: 4, 3: 3}
6 query: {2: 3, 3: 2}
7 query: answer is 2
The sum of the results for all the get queries is equal to 4 + 2 = 6.

Explanation:
Carly’s Catering provides meals for parties and special events. Write a program that prompts the user for the number of guests attending an event and then computes the total price, which is $35 per person. Display the company motto with the border that you created in the CarlysMotto2 class in Chapter 1, and then display the number of guests, price per guest, and total price. Also display a message that indicates true or false depending on whether the job is classified as a large event—an event with 50 or more guests. Save the file as CarlysEventPrice.java.
Answer:
Answered below
Explanation:
Scanner n = new Scanner(System.in);
System.out.print("Enter number of guests: ");
int numOfGuests = n.nextline();
double pricePerGuest = 35.0;
double totalAmount = numOfGuests * pricePerGuest;
String event = " ";
if ( numOfGuests >= 50){
event = "Large event";
}else{
event = "small event";
}
System.out.print(numOfGuests);
System.out.println(pricePerGuest);
System.out.println( totalAmount);
System.out.println(event);
