Answer:
The right answer is option 2: instance variables and their values
Explanation:
Let us define what an object is.
An object is a blueprint of a real-world identity. The instances are the reference to the object. Multiple instances of an object type can be made.
The instance variables and their values help us to determine the state of the object.
Hence,
The right answer is option 2: instance variables and their values
1.16 LAB: Input and formatted output: House real estate summary Sites like Zillow get input about house prices from a database and provide nice summaries for readers. Write a program with two inputs, current price and last month's price (both integers). Then, output a summary listing the price, the change since last month, and the estimated monthly mortgage computed as (currentPrice * 0.051) / 12 (Note: Output directly. Do not store in a variable.).
Ex: If the input is:
200000 210000
the output is:
This house is $200000. The change is $-10000 since last month.
The estimated monthly mortgage is $850.0.
Note: Getting the precise spacing, punctuation, and newlines exactly right is a key point of this assignment. Such precision is an important part of programming.
import java.util.Scanner;
public class LabProgram {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
int currentPrice;
int lastMonthsPrice;
currentPrice = scnr.nextInt();
lastMonthsPrice = scnr.nextInt();
/* Type your code here. */
}
Answer:
Please find the complete code and the output in the attachement.
Explanation:
In the code, a class "LabProgram" is defined, and inside the main method two integer variable "currentPrice and lastMonthsPrice" is defined that uses the scanner class object is used for a user input value, and in the next step, two print method is declared that print the calculate of the integer variable.
The program is an illustration of output formats in Java
The statements that complete the program are:
System.out.printf("This house is $%d. The change is $%d since last month.\n",currentPrice,(currentPrice - lastMonthsPrice));System.out.printf("The estimated monthly mortgage is $%.1f.\n",(currentPrice * 0.051)/12);To format outputs in Java programming language, we make use of the printf statement, followed by the string literal that formats the required output
Take for instance:
To output a float value to 2 decimal place, we make use of the literal "%.2f"

var nums = [1,1, 2, 3, 5, 8, 13, 21];
var copyNums = [1,1, 2, 3, 5, 8, 13, 21];
for(var i=0; i < copyNums.length; i++){
if(copyNums[i] == 1){
insertItem(copyNums,i,"hello");
}
}
This code will create an infinite loop. Why does it create an infinite loop?
Answer:
Explanation:
This code creates an infinite loop because it is detecting that the first value of copyNums is 1, therefore it runs the insertItem code. This code then adds the value "hello" to the array in position i which would be 0. Then moves to the next value of the array, but since the element "hello" pushed the value 1 to the next index then the code just repeats itself with the same value of 1. This continues to happen because every time the value "hello" is added it simply pushes the 1 to the next index and repeats the same code.
Answer:
[tex]var nums = [1,1, 2, 3, 5, 8, 13, 21];
var copyNums = [1,1, 2, 3, 5, 8, 13, 21];
for(var i=0; i < copyNums.length; i++){
if(copyNums[i] == 1){
insertItem(copyNums,i,"hello");
}

What is the recommended solution if a computer performs slowly?
Answer:
Not sure what the class/context is, but here's what I'd do to diagnose a problem like that:
- Check to see what programs have high utilization of system resources in task manager and end them
- Prevent background startup processes from occuring on restart or from running in the background during normal use
- Figure out what hardware component is bottlenecking the system and upgrade it (HDD to SSD would be one example)
- If the issue is malware related, I would "flatten" the PC by wiping the entire system and reinstalling the OS (though some malware can persist even across this)
Source: I've worked as labs support
If a computer is performing slowly, there are several recommended solutions one can try to improve its performance, such as closing unnecessary programs, restarting the computer, etc.
Reviewing the programs that automatically start when the computer boots up and disabling unnecessary startup programs to reduce the time it takes for the computer to start and free up system resources. The specific solution may vary depending on the computer's operating system, hardware, and specific performance issues. It's always a good idea to back up important files before making any changes to your computer's configuration. If the performance issues persist, seeking assistance from a computer technician or IT professional may be necessary.

Use the factorial operation to evaluate 10!.
A) 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1
B) 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1
C) 10 + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1
D) 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1
Answer:
D
Explanation:
The definition of n! is n x (n-1) x (n-2) x ... x 1.
So 10! = 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 i.e. D.
Answer:
D) 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1
Explanation:
The problem here is to use the factorial method to find;
10!
The factorial of any number is given as:
a! = (a - 1) x (a - 2) .........(a - n)
It is the product of any integer from 1 to that number.
So;
10! = 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1
The solution is therefore 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1

Write a program that reads an integer between o and 1000 and adds all the digits in the integer. For example, if an integer is 932, the sum of all the digits is 14. Hint: Use the % operator to extract digits, and use the / operator to remove the extracted digit. For instance, 932 % 10=2 and 932/10 =93. Here is a sample run:
Enter a number between 0 and 1000 : 999
The sum of digits is 27.
Answer:
Answered below
Explanation:
#Program is written in Python programming language
digit = 0
sum = 0
num = int(input("Enter a number between 0 and 1000: ")
#Check that number is within the valid range
if num > 0 and num <= 1000:
while num != 0:
#Isolate each digit
digit = num % 10
sum = sum + digit
#Remove isolated digit from number
num = num/10
else:
print("Number is not within valid range")
#print total sum of digits

Assuming dataFile is an ofstream object associated with a disk file named payroll.dat, which of the following statements would write the value of the salary variable to the file
A) cout <
B) ofstream
C) dataFile << salary;
D) payroll.dat <
Answer:
dataFile << salary;
Explanation:
To write salary to a file (payroll.dat) using ofstream, you make use of the following instruction:
ofstream dataFile;
myfile.open ("payroll.dat");
myfile <<salary;
myfile.close();
This line creates an instance of ofstream
ofstream dataFile;
This line opens the file payroll.dat
myfile.open ("payroll.dat");
This is where the exact instruction in the question is done. This writes the value of salary to payroll.dat
myfile <<salary;
This closes the opened file
myfile.close();
When defining a class, it is a best practice to declare ____ as private. constructors mutators nothing should be private accessors variables
Answer:
The answer is "variables".
Explanation:
It is necessary to declare a variable privately when declaring a class because the private variable 'protects' the code while it is in operation. It may not aim to protect it at this stage from changing the codes themselves for other developers. Its purpose of the so-called "data hiding" is to hold the internal data from many other classes using the class protected.

Write a program that calculates the shipping charges for parcel. The program should ask the user to enter two floating point values:
The weight of a parcel in pounds
The shipping rate per pound
The program calculates and displays the total shipping charges based on the parcel’s weight and shipping rate per pound.
Your program should print dollars and cents with two decimal places such as 32.85, and not 32.8467777.
Hint: Until we learn how to format output, we will use this little trick. You can round a floating-point value to the nearest hundredth by adding 0.005, multiplying by 100, converting the result to an integer, and then dividing by 100. This trick is not perfect but works well with most values.
Here is a sample of what a typical run of this program looks like where the user entered the values 4.75 for the weight and 2.55 for the shipping rate per pound:
Shipping Charges Calculator
Enter the weight of your parcel in pounds: 4.75
Enter the shipping price per pound: 2.55
The weight of your parcel is 4.75 pounds
The shipping price per pound is $ 2.55
The shipping charges for your parcel is $ 12.11
NOTE: Please remember that your program will be graded in terms of:
correctness: it performs the calculations correctly and uses proper arithmetic expressions: 75% (graded by Zybooks)
code style: good variable names, comments, proper indentation and spacing: 25% (grade by the TAs)

# Calculate the total price per pound

Type a statement using srand() to seed random number generation using variable seedVal. Then type two statements using rand() to print two random integers between (and including) 0 and 9. End with a newline. Ex:
5.
7.
Note: For this activity, using one statement may yield different output (due to the compiler calling rand() in a different order). Use two statements for this activity. Also, after calling srand() once, do not call srand() again. (Notes)
1 #include
2 #include //
3 Enables use of rand ()
4 int main(void) ( int seedval;
6.
7. scanf ("%d", &seedval);

scanf ("%d", &seedval);
srand(seedval);
printf("%d\n", rand()%10);
printf("%d\n", rand()%10);
return 0;
}
Explanation:
The given code is poorly formatted. So, I picked what is usable from the code to write the following lines of code:
#include<stdio.h>
#include<stdlib.h>
int main(void){
This line declares seedval as integer
int seedval;
This line gets user input for seedval
scanf ("%d", &seedval);
This line calls the srand function to generate random numbers
srand(seedval);
This prints a random number between 0 and 9
printf("%d\n", rand()%10);
This also prints a random number between 0 and 9
printf("%d\n", rand()%10);
return 0;
