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.
Declare a typedef struct named jumper_t that will have four parts: character array name that is 16 in length, double array of tries that is N_TRIES in length, double best_jump, double deviation 2. Write one line to declare an array variable, named jlist of the above struct type, with a length of ten. No initialization required.
Answer:
The typedef struct is as follows:
typedef struct jumper_t {
char name[16];
double tries[N_TRIES];
double best_jump;
double deviation;
} jumper_t;
The declaration of jlist is:
jumper_t jlist[10];
Explanation:
This defines the typedef structure
typedef struct jumper_t {
The following declares the variables as stated in the question
char name[16];
double tries[N_TRIES];
double best_jump;
double deviation;
}
This ends the typedef definition
jumper_t;
(b) The declaration of array jlist is:
jumper_t jlist[10];
1 convert (101011)2 ( )10 ? convert(596)10= ( )16 ? convert( 101011101)2 ( )16 ? convert(37)10= ( )2 ?
(a) convert (101011)₂ = ( )₁₀ ?
(b) convert(596)₁₀= ( )₁₆ ?
(c) convert( 101011101)₂ = ( )₁₆ ?
(d) convert(37)₁₀= ( )₂ ?
Answer:(a) (101011)₂ = ( 43)₁₀
(b) (596)₁₀= ( 254)₁₆
(c) ( 101011101)₂ = ( 15D)₁₆
(d) (37)₁₀= ( 100101)₂
Explanation:(a) convert (101011)₂ = ( )₁₀
This means that (101011)₂ be converted to base 10 (decimal).
To convert from binary to decimal, find the sum of the binary digits times their power of 2. i.e
(101011)₂ = 1 x 2⁵ + 0 x 2⁴ + 1 x 2³ + 0 x 2² + 1 x 2¹ + 1 x 2⁰
(101011)₂ = 1 x 32 + 0 x 16 + 1 x 8 + 0 x 4 + 1 x 2 + 1 x 1
(101011)₂ = 32 + 0 + 8 + 0 + 2 + 1
(101011)₂ = 43₁₀
Therefore, (101011)₂ = ( 43)₁₀
(b) convert(596)₁₀= ( )₁₆
This means that (596)₁₀ be converted to base 16 (hexadecimal).
To convert from decimal to hexadecimal,
i. start by dividing the decimal number by 16 taking note of the result and the remainder.
ii. divide the result obtained in (i) by 16 and take note of the new result and the remainder.
iii. repeat steps i and ii until the result is 0.
iv. the result is a combination of the remainders starting from the last.
16 | 596
16 | 37 r 4
16 | 2 r 5
| 0 r 2
Now combine the remainders starting from the bottom up. i.e
254₁₆
Therefore, (596)₁₀= ( 254)₁₆
(c) convert ( 101011101)₂ = ( )₁₆
This means that (101011101)₂ be converted to base 16 (hexadecimal).
To convert from binary to hexadecimal,
i. starting from the rightmost bit, group the binary digits into a group of 4 bits as follows
101011101 => 1 0101 1101
ii. the group that does not contain 4 bits is padded with 0s
101011101 => 0001 0101 1101
iii. using the hexadecimal table, convert each group to hexadecimal as follows.
0001 = 1
0101 = 5
1101 = D
iv. combine the result
15D
Therefore, ( 101011101)₂ = ( 15D)₁₆
(d) convert(37)₁₀= ( )₂
This means that (37)₁₀ be converted to base 2 (binary).
To convert from decimal to binary,
i. start by dividing the decimal number by 2 taking note of the result and the remainder.
ii. divide the result obtained in (i) by 2 and take note of the new result and the remainder.
iii. repeat steps i and ii until the result is 0.
iv. the result is a combination of the remainders starting from the last.
2 | 37
2 | 18 r 1
2 | 9 r 0
2 | 4 r 1
2 | 2 r 0
2 | 1 r 0
| 0 r 1
Now combine the remainders starting from the bottom up. i.e
100101₂
Therefore, (37)₁₀= ( 100101)₂
SummaryIn this lab, you complete a partially written C++ program that includes a function named multiplyNumbers() that multiplies two int values to find their product.Three ints should be passed to the multiplyNumbers() function, the two numbers to be multiplied (num1 and num2) should be passed by value, and another int (product) to hold the product of the two numbers should be passed by reference, enabling the multiplyNumbers() function to change its value.The source code file provided for this lab includes the necessary variable declarations and input and output statements. Comments are included in the file to help you write the remainder of the program.Instructions:Open the source code file named MultiplyTwo.cpp using the code editor.Write the multiplyNumbers() function, the function declaration, and the function call as indicated by the comments.Execute the program by clicking "Run Code."Rewrite the multiplyNumbers() function to pass the two numbers (num1 and num2) by value and to pass product by address.Execute the program. It should generate the same output.// MultiplyTwo.cpp - This program calculates the product of two numbers.// It demonstrates pass by reference and then pass by address.// Input: None// Output: The product of two numbers#include using namespace std;// Write function declaration hereint main(){int num1 = 10;int num2 = 20;int product = 0;// Print value of product before function callcout << "Value of product is: " << product << endl;// Call multiplyNumbers using pass by reference for product// Print value of calculated productcout << num1 << " * " << num2 << " is " << product << endl;return 0;} // End of main function// Write multiplyNumbers function here; use pass by reference for result of multiplication. Then use pass by address.
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; }

Telephone – Cable/ Radio -
Answer:
Telephone – Cable/ Radio - Wireless
Implement a class named MyArrayList that extends class the java.util. ArrayList. The class MyArrayList overrides the add(obj) method in the following way: it adds obj into the list if the object does not occur in the list or it occurs in the list only once; otherwise, if the object occurs in the list more than once, then the method does nothing.
Answer:
import java.util.ArrayList;
import java.util.Collections;
public class MyArrayList<T> extends ArrayList<T> {
public boolean add(T obj) {
if (Collections.frequency(this, obj) < 2) {
return super.add(obj);
}
return false;
}
}
Explanation:
According to the requirement, an element with the same value can occur at most twice in the list.
The Collections.frequency utility is useful to count the occurrances.
Sure, here's an implementation of the `MyArrayList` class that extends `java.util.ArrayList` and overrides the `add` method as described:
```java
import java.util.ArrayList;
import java.util.HashMap;
import java.util.Map;
public class MyArrayList<E> extends ArrayList<E> {
"ATTHERATE"Override
public boolean add(E obj) {
// Count occurrences of each element in the list
Map<E, Integer> countMap = new HashMap<>();
for (E element : this) {
countMap.put(element, countMap.getOrDefault(element, 0) + 1);
}
// Check if obj occurs in the list only once or not at all
if (!countMap.containsKey(obj) || countMap.get(obj) == 1) {
return super.add(obj);
}
// If obj occurs more than once, do nothing
return false;
}
}
```
In this implementation, the `add` method first counts the occurrences of each element in the list using a `HashMap`.
Then, it checks whether the given object `obj` occurs only once or not at all in the list. If so, it adds the object to the list using the `super.add(obj)` call.
If `obj` occurs more than once, the method does nothing by returning `false`. This way, the `MyArrayList` class ensures that duplicates are added only once, or not at all, as required.

Write a program that allows the user to enter the last names of five candidates in a local election and the number of votes received by each candidate. The program should then output each candidate's name, the number of votes received, and the percentage of the total votes received by the candidate. Your program should also output the winner of the election.
i have this
#include
#include
#include
using namespace std;
int findMax(int votes[]);
void main()
{
int votes[20];
string name[10];
int total=0;
float percent[10];
int m, i, loc;
cout<<"Enter the names of candidates in local election and number of votes:"<
for(int i=0;i<5;i++)

for(i=0;i<5;i++)
{
total=total+votes[i];
}
for(i=0;i<5;i++)
{
percent[i]=((votes[i]/total)*100);
}
cout<<"Candidate"<<'\t'<<"VotesReceived"<<'\t'<<"% of Total Votes"<

for(i=1;i<5;i++)

if(votes[i]>max)
{
max=votes[i];
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.
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.

Software that enables the organization to centralize data is called A. Data Repository B. Data Base Management System C. Data Warehouse D. Data Mart E. Data File
Answer:
B. Data Base Management System
Explanation:
A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to effectively and efficiently create, store, modify, retrieve, centralize and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.
Generally, a database management system (DBMS) acts as an intermediary between the physical data files stored on a computer system and any software application or program.
A data dictionary can be defined as a centralized collection of information on a specific data such as attributes, names, fields and definitions that are being used in a computer database system.
In a data dictionary, data elements are combined into records, which are meaningful combinations of data elements that are included in data flows or retained in data stores.
This ultimately implies that, a data dictionary found in a computer database system typically contains the records about all the data elements (objects) such as data relationships with other elements, ownership, type, size, primary keys etc. This records are stored and communicated to other data when required or needed.
Hence, a software that enables the organization to centralize data, manage the data efficiently while providing authorized users a significant level of access to the stored data, is called a Data Base Management System (DBMS).

write a java program to input the corresponding data to print the result of the following expression
y=ax²+bx+c
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);
float a, b, c, x, y;
a = input.nextFloat();
b = input.nextFloat();
c = input.nextFloat();
x = input.nextFloat();
y = a * x * x + b * x + c;
System.out.print(y); }}
Explanation:
This declares all variables
float a, b, c, x, y;
The next 4 lines get input for a, b, c and x
a = input.nextFloat();
b = input.nextFloat();
c = input.nextFloat();
x = input.nextFloat();
This calculates the value of y using [tex]y = ax^2 + bx + c[/tex]
[tex]y = a * x * x + b * x + c;[/tex]
This prints the calculated value of y

Answer:
(b)
public abstract class Rectangle {

Explanation:When a class is declared with the abstract keyword, the class is called an abstract class. Abstract classes cannot be instantiated and may include one or more abstract methods. If a class contains an abstract method, then it (the class) must be declared abstract.
In Java, abstract classes are defined using the following format:
[access_modifier] abstract class [name_of_class]
[access_modifier] specifies the access modifier of the class which could be public, private, e.t.c
abstract is the keyword that specifies that the class is an abstract class.
class is a keyword used for defining classes
name_of_class specifies the name of the class.
The only option that fulfils this format is option b where;
(i) The access modifier is public
(ii) The name of the class is Rectangle
Option a is not correct because the abstract keyword is supposed to come before the class keyword.
Option c is not correct because the keyword abstract is missing. In other words, the class must be declared abstract since it contains abstract method findArea();
Option d is not correct because the abstract keyword is supposed to come before the class keyword.

explain 5 important of using a word processor
Answer:
Spelling
Word processors contain an electronic spell checker. The student writer has immediate feedback about misspelled words. Student must discern which of the computer-generated spellings is correct for the context. Teachers no longer have to red-ink spelling errors. They can focus on the few exceptions the spellchecker does not catch.
Security
Teachers and students gain a sense of security about losing assignments. When the student saves her work, she avoids the possibility of the assignment being lost or misplaced. If an assignment is ever misplaced, a replacement can be easily printed.
Legibility
Teachers benefit by receiving a readable copy that is easy to grade. Students with poor handwriting can increase their scores with better looking papers. Students should be instructed to turn in copies of work in a readable font.
Publishing
Work done on a word processor can easily published on a bulletin board. Teachers can create electronic anthologies of their students' writings. Each student can receive an electronic copy of published works with no printing costs.
Mobility
Work done on a word processor and saved on the Internet is highly portable and accessible from any computer with Internet access. Dogs do not eat papers in cyberspace. "I forgot it at home" is irrelevant. Just log onto the nearest computer and your work appears on the screen.

write a java program to input two double type numbers and by using suitable mathematical functions print the maximum and minimum numbers out of the two numbers.
[tex]java \: me \: likhna \: ok[/tex]
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);
