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 class called Person that has two data members - the person's name and age. It should have an init method that takes two values and uses them to initialize the data members.Write a separate function (not part of the Person class) called std_dev that takes as a parameter a list of Person objects (only one parameter: person_list) and returns the standard deviation of all their ages (the population standard deviation that uses a denominator of N, not the sample standard deviation, which uses a different denominator).
Answer:
class Person(object):
def __init__(self, name, age):
self.name = name
self.age = age
def std_dev(person_list):
average = 0
for person in person_list:
average += person.age
average /= len(person_list)
total = 0
for person in person_list:
total += (person.age - average) ** 2
return (total / (len(person_list) )) ** 0.5
Explanation:
The class "Person" is a python program class defined to hold data of a person (name and age). The std_dev function accepts a list of Person class instances as an argument and returns the calculated standard deviation of the population.

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();

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.

To do this you'll need to use malloc to assign memory to the pointers used. You'll also need to use free to unassign that memory at the end of the program using the free. Both of these are in stdlib.h.
#include <stdlib.h>
#include <stdio.h>
#define SIZE_X 3
#define SIZE_Y 4
int main(void){
int **matrix, i, j;
// allocate the memory
matrix = (int**)malloc(SIZE_X * sizeof(int*));
for(i = 0; i < SIZE_X; i++){
matrix[i] = (int *)malloc(SIZE_Y * sizeof(int));
}
// assign the values
for(i = 0; i < SIZE_X; i++){
for(j = 0; j < SIZE_Y; j++){
matrix[i][j] = SIZE_Y * i + j + 1;
}
}
// print it out
for(i = 0; i < SIZE_X; i++){
for(j = 0; j < SIZE_X; j++){
printf("%d, %d: %d\n", i, j, matrix[i][j]);
}
}
// free the memory

How does calculate() work?
Answer:
calculate works by determining the amount of something
Explanation:
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];

if(copyNums[i] == 1){
insertItem(copyNums,i,"hello");

Adding a paper clip to the vertical stabilizer of your glider will have what effect on its Center of Gravity (CG)?
The CG would move toward the rear.
The CG would stay the same.
The CG would move toward the nose.
O The CG would move lower
Answer:
the CG would move toward the rear.
Explanation:
Adding a paper clip to the vertical stabilizer of your glider will, the CG would move toward the rear. The correct option is A.
What is center of gravity?The place on an item where the force of gravity is thought to act is known as the center of gravity (CG).
The gravitational pull is thought to be focused at the point where an object weighs on average. Depending on the object's size, shape, and mass distribution, the center of gravity will be in one place or another.
The impact of adding a paper clip to your glider's vertical stabilizer is to shift the center of gravity (CG) to the back of the glider.
This is due to the fact that the paper clip adds weight to the glider's rear, moving the center of mass there and, as a result, the center of gravity.
Thus, the correct option is A.

A drink costs 2 dollars. A taco costs 3 dollars. Given the number of each, compute total cost and assign totalCost with the result. Ex: 4 drinks and 6 tacos yields totalCost of 26.
*/
int main() {
int numDrinks = 0;
int numTacos = 0;
int totalCost = 0;
numDrinks = 4;
numTacos = 6;
/* Your solution goes here */
totalCost = (2 * numDrinks) + (3 * numTacos);
cout << "Total cost: " << totalCost << endl;
return 0;
}
Answer:
See Explanation
Explanation:
The question has been answered; however, the program is not dynamic enough because the output will always be 26.
To make it dynamic, replace the following lines of code:
numDrinks = 4;
numTacos = 6;
with:
cout<<"Number of drinks: ";
cin>>numDrinks;
cout<<"Number of Tacos: ";
cin>>numTacos;
The above lines of code will let the user input different values for numDrinks and numTacos each time the program is executed.
Computing the total cost using code can be represented as follows:
def total_cost(no_of_drinks, no_of_talcos):
totalCost = 2*no_of_drinks + 3*no_of_talcos
return totalCost
print(total_cost(4, 6))
Python code explanation:A function named total_cost is declared and it accept the parameters no_of_drinks and no_of_talcos.
The totalCost is used to store the result of the cost of the total drinks and tacos bought in dollars.
Then, we return the totalCost.
Finally, we use the print statement to call the function with its required parameters.

Write a method named numUnique that accepts a sorted array of integers as a parameter and that returns the number of unique values in the array. The array is guaranteed to be in sorted order, which means that duplicates will be grouped together. For example, if a variable called list stores the following values: int[] list
Answer:
The method in Java is as follows:
public static int numUnique(int list[]) {
int unique = 1;
for (int i = 1; i < list.length; i++) {
int j = 0;
for (j = 0; j < i; j++) {
if (list[i] == list[j])
break;
}
if (i == j)
unique++;
}
return unique;
}
Explanation:
This line defines the numUnique method
public static int numUnique(int list[]) {
This initializes the number of unique elements to 1
int unique = 1;
This iterates through the list
for (int i = 1; i < list.length; i++) {
The following iteration checks for unique items
int j = 0;
for (j = 0; j < i; j++) {
if (list[i] == list[j]) If current element is unique, break the iteration
break;
}
if (i == j)
unique++;
}
This returns the number of unique items in the list
return unique;
