A Consider the following method definition. The method printAllCharacters is intended to print out every character in str, starting with the character at index 0. public static void printAllCharacters (String str) for (int x = 0; x< str.length(); x++) // Line 3 System.out.print(str.substring(x, x + 1)); The following statement is found in the same class as the printAllCharacters method. printAllCharacters ("ABCDEFG"); Which choice best describes the difference, if any, in the behavior of this statement that will result from changing x < str.length() to x <= str.length() in line 3 of the method?
Α) The method call will print fewer characters than it did before the change because the loop will iterate fewer times.
B) The method call will print more characters than it did before the change because the loop will iterate more times.
C) The method call, which worked correctly before the change, will now cause a run-time error because it attempts to access a character at index 7 in a string whose last element is at index 6.
D) The method call, which worked correctly before the change, will now cause a run-time error because it attempts to access a character at index 8 in a string whose last element is at index 7.
E) The behavior of the code segment will remain unchanged.
Answers
Answer:
(c) The method call, which worked correctly before the change, will now cause a run-time error because it attempts to access a character at index 7 in a string whose last element is at index 6.
Explanation:
Given
printAllCharacters method and printAllCharacters("ABCDEFG");
Required
What happens when x < str.length() is changed to x <= str.length()
First, we need to understand that str.length() gets the length of string "ABCDEFG"
There are 7 characters in "ABCDEFG".
So: str.length() = 7
The first character is at index 0 and the last is at index 6
Next, we need to simplify the loop:
for (int x = 0; x< str.length(); x++) means for (int x = 0; x< 7; x++)
The above loop will iterate from the character at the 0 index to the character at the 6th index
while
for (int x = 0; x<=str.length(); x++) means for (int x = 0; x<=7; x++)
The above loop will iterate from the character at the 0 index to the character at the 7th index
Because there is no character at the 7th index, the loop will return an error
Hence: (c) is correct
Following are calculations to the given method.
Given:
Method printAllCharacters and printAllCharacters("ABCDEFG") are both required.
To find:
What happens if you change x <str.length() to x = str.length()?
Solution:
To begin, we must recognize that str. length() returns the length of the string "ABCDEFG"."ABCDEFG" is made up of seven letters.As just a result, str.length() = 7The first character is at index 0 while the last is at index 6. The loop should therefore be simplified:
for (int x = 0; x< str.length(); x++) means for (int x = 0; x< 7; x++)
Its loop above should iterate from character 0 through character 6.when
for (int x = 0; x<=str.length(); x++) stands as for (int x = 0; x<= 7; x++).
The loop above will iterate from the character from index 0 to a character at index 7.The loop will produce an error since there are no characters at the 7th index.Therefore, the final answer is "Option (c)"

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
Answers
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;
}

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 <
Answers
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();
Adding a paper clip to the vertical stabilizer of your glider will have what effect on its Center of Gravity (CG)?

Answers
Answer:

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.

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()

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.

Its purpose of the so-called "data hiding" is to hold the internal data from many other classes using the class protected.

}
}
This code will create an infinite loop. Why does it create an infinite loop?
Answers
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];

3.93: -0.7, -0.71
4.71: 0.0, -1.0

double value = 0.431675;
value = value * 100; // 43.1675
value = Math.round(value) // 43.0

The program in Java is:
import java.lang.*;
public class MyClass {
public static void main(String args[]) {
for(int i= 0;i<360;i+=45){
double angle = Math.round(Math.toRadians(i)*100.0)/100.0;
double cosX = Math.round(Math.cos(angle)*100.0)/100.0;
double sinX = Math.round(Math.sin(angle)*100.0)/100.0;
System.out.println(angle+": "+cosX +" "+ sinX);
}
}
}
Explanation:
This line iterates through the angles from 0 to 360 or 0 to 2*Pi
for(int i= 0;i<360;i+=45){
This calculates the angle to radians
double angle = Math.round(Math.toRadians(i)*100.0)/100.0;
This calculats the cosine of the angle rounded to 2 decimal place
double cosX = Math.round(Math.cos(angle)*100.0)/100.0;
This calculats the sine of the angle rounded to 2 decimal place
double sinX = Math.round(Math.sin(angle)*100.0)/100.0;
This prints the required output
System.out.println(angle+": "+cosX +" "+ sinX);

/* Your solution goes here */
totalCost = (2 * numDrinks) + (3 * numTacos);
cout << "Total cost: " << totalCost << endl;
return 0;
}
Answers
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.
