#include <stdio.h>//header file
double estPi(int precision)//defining a method estPi that accepts value in parameter
{
double pi = 0, sign = 1, n = 1;//defining a double variable
while (n <= precision) //use while loop that checks n value less than equal to precision
{
pi += sign / n;//defining pi variable that holds quotient value
sign *= -1;//holding value in sign value
n += 2;//increment value in n
}
return 4 * pi;//return value
}
int main() //main method
{
int n;//defining an integer variable

Answers
Answer:
Declare the method prototype using:
void multiplyNumbers(int x, int y,int &product);
Call the function using:
multiplyNumbers(num1, num2,product);
Lastly, the method is as follows:
void multiplyNumbers (int x, int y,int &product) {
product = x * y;
return; }
Explanation:
Declare the method prototype using
void multiplyNumbers(int x, int y,int &product);
Call the function using
multiplyNumbers(num1, num2,product);
The method is as follows; the & written in front of product implies that product is passed by reference
void multiplyNumbers (int x, int y,int &product) {
This calculate the product
product = x * y;
This returns nothing
return; }

If myClass has a constructor with a parameter of type String, select the other constructor that should be included.
a. public void myClass( ) {. . .}
b. public myClass(int value ) {. . .}
c. public myClass(String str1, String str2) {. . .}
d. public myClass( ) {. . .}
Answers
Answer:
d. public myClass( ) {. . .}
Explanation:
A constructor is a special method that is called when an object of a class is created. It is also used to initialize the instance variables of the given class. A class may have one or more constructors provided that these constructors have different signatures. A class that does not have a constructor explicitly defined has a default parameterless constructor.
Having said these about a constructor, a few other things are worth to be noted by a constructor.
i. In Java, a constructor has the same name as the name of its class.
For example, in the given class myClass, the constructor(s) should also have the name myClass.
ii. A constructor does not have a return value. It is therefore wrong to write a constructor like this:
public void myClass(){...}
This makes option a incorrect.
iii. When a constructor with parameters is defined, the default parameterless constructor is overridden. This might break the code if some other parts of the program depend on this constructor. So it is advisable to always explicitly write the default parameterless constructor.
This makes option d a correct option.
Other options b and c may also be correct but there is no additional information in the question to help establish or justify that.

Answers
Answer:
The program in Java is as follows:
import java.util.Scanner;
public class Main{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
double n1, n2;
n1 = input.nextDouble();
n2 = input.nextDouble();
double Max = Math.max(n1,n2);
double Min = Math.min(n1,n2);
System.out.println("Max: "+Max);
System.out.println("Min: "+Min); }}
Explanation:
This declares the numbers
double n1, n2;
This gets input for n1
n1 = input.nextDouble();
This gets input for n2
n2 = input.nextDouble();
This gets the max of both using the max function
double Max = Math.max(n1,n2);
This gets the min of both using the min function
double Min = Math.min(n1,n2);
This prints the max
System.out.println("Max: "+Max);
This prints the min
System.out.println("Min: "+Min);

Course sequence to satisfy the prerequisite
From the course prerequisite, we have:
[tex]1.\ LA15 \to None[/tex] and [tex]3.\ LA22 \to None[/tex]
This means that LA15 and LA22 are the base courses, and they have no prerequisite. So, we have:
[tex][LA15; LA22][/tex]
LA16 and LA31 have LA15 as their direct course prerequisite. So, the sequence becomes
[tex][LA15 \to [LA16, LA31]; LA22][/tex]
To complete the sequence, we read each course and place them other their prerequisite.

A program developed for a Web store represents customer account balances using a format that approximates real numbers. While testing the program, a software developer discovers that some values appear to be mathematically imprecise. Which of the following is the most likely cause of the imprecision?
A. The account balances are represented using a fixed number of bits, resulting in overflow errors.
B. The account balances are represented using a fixed number of bits, resulting in round-off errors.
C. The account balances are represented using an unlimited number of bits, resulting in overflow errors.
D. The account balances are represented using an unlimited number of bits, resulting in round-off errors.
Answers
Answer:
B.
Explanation:
The most likely reason for this would be that the account balances are represented using a fixed number of bits, resulting in round-off errors. Since all of the numbers being used are real numbers they would have a fixed 32 bits of data. When these values are multiplied or divided they can be irrational numbers that never end, and therefore are cut off in order to fit the available data. This would cause the numbers to be rounded and can lead to the answer being imprecise.

loc=i;
}
}
return loc;
}
But, it is saying that loc is not initialized, and it is also not calculating % of total votes or the winner of the election and I don't what to do to fix it.
Answers
Answer:
The following fix were made to the program
Change void main() to int main(), then set a return value at the end of the main function; e.g. return 0Remove system("pause"); It's not neededFor each of the array, change their lengths to 5 i.e. int votes[5]; string name[5]; and float percent[5];Lastly, calculate the percentage using: percent[i]=((votes[i]*100.0/total))Explanation:
(1) void main implies that the main function will not return any value. So, you change it to int main() and then set the return value
(2) There is no need to pause the program, so system.("pause") is not necessary.
(3) The question says there are 5 candidates. So, we set the arrays to accommodate inputs for 5 values
(4) percent array is declared as float; 100.0 will ensure that it calculates the percentage as a float value.
