Answer:
import java.util.Arrays;
public class swap{
public static void main(String []args){
int [] arr = {2,4};
swapValues(arr);
}
public static void swapValues(int[] values){
int temp;
System.out.println(Arrays.toString(values));
temp=values[0];
values[0]=values[1];
values[1] =temp;
System.out.println(Arrays.toString(values));
}
}
Explanation:
In the program above, we created the method swapValues that receives an array of integers as parameters. in the method definition, we created a temp variable that is used to swapp the element at index 0 and index 1. Java's Arrays.to string method is used to print the array before and after the swap.
Answer:
C code explained below
Explanation:
#include <stdio.h>
#include <stdbool.h>
int main(void) {
int userNum;
bool isPositive;
bool isEven;
scanf("%d", &userNum);
isPositive = (userNum > 0);
isEven = ((userNum % 2) == 0);
if(isPositive && isEven){
printf("Positive even number");
}
else if(isPositive && !isEven){
printf("Positive number");
}
else{
printf("Not a positive number");
}
printf("\n");
return 0;
}
Answer:
authentication
Explanation:
At the authentication process, there is a way of identifying a user, this is typically done by having the user enter a valid user name and valid password before access is granted. Here at authentication the process is based on each user having a unique set of criteria for gaining access.
The AAA server have to ascertain by comparing a user's authentication credentials with other user credentials stored in a database. In the event the credentials match, the user is granted access to the network. But on the other hand, If the credentials varies, and authentication fails then network access will be denied.
Answer:
// In the number.cpp file;
#include "Number.h"
#include <iostream>
using namespace std;
Number::Number(int number)
{
num = number;
}
void Number::SetNum(int number)
{
num = number;
}
int Number::GetNum()
{
return num;
}
ostream &operator<<(ostream &out, const Number &n)
{
out << "The value is " << n.num << endl;
return out;
}
// in the main.cpp file;
#include "Number.cpp"
#include <iostream>
using namespace std;
int main()
{
int input;
cin >> input;
Number num = Number(input);
cout << num;
return 0;
}
Explanation:
The main function in the main.cpp file prompts the user for the integer value to be displayed. The Number file contains defined functions and methods of the number class to set, get and display the "num" variable.
