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 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
print(sum)

Answer:
d. plug it into the charger.
Explanation:
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();

Conside following prototype of a function
int minArray(int [], int );
Which of the option is correct way of function CALL assuming following arraydeclaration
int x[5] = {7,4,6,2,3};*
a) minArray(x,5);
b) minArray(x[],10);
c) minArray(x[5],5);
d) minArray(5,x);
Answer:
The answer is "Option a"
Explanation:
Following are the code to this question:
#include <stdio.h>//header file
int minArray(int x[], int n)//defining method minArray that accepts two parameters
{
for(int i=0;i<n;i++)//defining loop for print value
{
printf("%d\n",x[i]);//printf array value
}
}
int main()//defining main method
{
int x[] ={7,4,6,2,3};//defining array that hold values
int n=5;//defining integer variable
minArray(x,5);//calling method minArray
return 0;
}
In this code, a method "minArray" is defined, that accepts two parameters array and an integer variable in its parameter, and in the next step, the for loop is declared, that uses the print method to prints its value.
In the next step, the main method is declared, which declared an array and holds its values and defines an integer variables, and calls the method "minArray".

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"

Explanation:
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);
8.
9.
10 srand(int seedval);
11 printf("%d\n", srand());
12 printf("%d\n", srand());
13
14 return e;
15 }
Answer:
#include<stdio.h>
#include<stdlib.h>
int main(void){
int 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;
}
Consider the following class designed to store weather statistics at a particular date and time:
public class WeatherSnapshot
{
private int tempInFahrenheit;
private int humidity; // value of 56 means 56% humidity
private int dewPoint; // in degrees Fahrenheit
private String date; // stores the date as a String
private int time; // in military time, such as 1430 = 2:30 pm
private boolean cloudy; // true if 25% or more of the sky is covered
// constructor not shown, but it initializes all instance variables
// postcondition: returns temperature
public int getTemp()
{
return tempInFahrenheit;
}
// postcondition: returns date
public String getDate()
{
return date;
}
// postcondition: returns true if precipitation is likely; false otherwise
public boolean precipitationLikely()
{
// implementation not shown
}
// other methods not shown
}
Suppose a WeatherSnapshot object named currentWeather has been correctly instantiated in a client class. Which of the following will correctly call the precipitationLikely method?
A. boolean couldRain = precipitationLikely();
B. boolean couldRain = currentWeather.precipitationLikely();
C. boolean couldRain = currentWeather.precipitationLikely(true);
D. double percentChanceOfRain = precipitationLikely();
E. double percentChanceOfRain = currentWeather.precipitationLikely();
Answer:
The answer is "Option b".
Explanation:
In this question, It took the boolean parameter, which may use the couldRain as the precipitationLikely precipitation method as the boolean variable because the precipitationLikely is not a static type, and it can name this method utilizing object is called currentWeather, that's why the choice b is correct.
