Human resources planning is made as it's useful helping an organization meet its future demands by supplying the organization with the appropriate people.
Human resource planning also allows organizations plan ahead in order to have a steady supply of effective and skilled employees. It also brings about efficient utilization of resources. Lastly, it leads to better productivity and organizational goals will be achieved.
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++)
{
cin>>name[i];
cin>>votes[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"<
cout<
for(i=0;i<5;i++)
{
cout<
}
cout<<"Total:"<
m=findMax(votes);
cout<<"Winner of the election is"<
system("pause");
}
int findMax(int votes[])
{
int i,max,loc;
max=votes[0];
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.

Which of the following class definition defines a legal abstract class Group of answer choices
(a)
public class Rectangle abstract {
public abstract double findArea ( );
}
(b)
public abstract class Rectangle {
public abstract double findArea ( );
}
(c)
public class Rectangle {
public abstract double findArea ( );
}
(d)
public class abstract Rectangle {
public abstract double findArea ( );
}
Answer:
(b)
public abstract class Rectangle {
public abstract double findArea ( );
}
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.

(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
In which SDLC step does the company translate broad, user-oriented systems requirements into the detailed specifications used to create a fully developed system
Answer:
Physical design.
Explanation:
Systems development life cycle (SDLC) is a strategic process that involves determining the overall system architecture, which is typically comprised of hardware, end users, physical processing components, software, and the communication channel that will effectively and efficiently satisfy the essential requirements of the system.
The system inputs and outputs is typically designed along with a plan of how the system's features will be navigated.
Basically, system design is divided into two (2) categories and these includes;
I. Logical design.
II. Physical design.
Furthermore, the design of service systems involves the process of planning, creating infrastructure, building communication, organizing staffs and standardization of a system so as to improve its quality and business relationships between the service provider and its clients.
In the physical design of systems development life cycle (SDLC), broad, user-oriented systems requirements are obtained from end users by companies and then translated into the detailed specifications that would be used to create a fully developed system.

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.

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);
