In symmetric encryption the same key is used to encrypt and decrypt a message. in asymmetric encryption different keys are used
Brrunno [24]

A useful advantage of Asymmetric encryption over symmetric encryption is that there is no secret channel necessary for the exchange of the public key, unlike in the symmetric encryption which requires a secret channel to send the secret key.  

Another advantage of Asymmetric encryption is that is has increased security. Asymmetric uses two different keys (Public and private) for both encryption and decryption of data while symmetric uses one.

// The program below checks if an array is sorted or not

// Program is written in C++ Programming Language.

// Comments are used for explanatory purpose

//Program Starts here

#include<iostream>

using namespace std;

//Function to check if the array is sorted starts here

int isSorted(int arr[], int count)

{

// Check if arrays has one or no elements

if (count == 1 || count == 0) {

return 1;

}

else

{

// Check first two elements

if(arr[0] >= arr[1])

{

return 0; // Not sorted

}

else

{ // Check other elements

int check = 0;

for(int I = 1; I<count; I++){

if (arr[I-1] > arr[I]) { // Equal number are allowed

check++; // Not sorted

}

}

}

if(check==0)

return isSorted(arr, count - 1); //Sorted

else

return 0; // Not sorted

}

// Main Method starts here

int main()

{

int count;

cin<<count;

int arr[count];

for(int I = 1; I<=count; I++)

{

cin>>arr[I-1];

}

int n = sizeof(arr) / sizeof(arr[0]);

if (isSorted(arr, n))

cout << "Array is sorted";

else

cout << "Array is not sorted";

"in program arrays12.java a swap method is called. does the swap method exchange parameter values x and y?"
horrorfan [7]
<h2>Yes the swap method exchange parameter values if passed by reference or the value gets changed inside the function.</h2>

Explanation:

Since the program is not given, I will try to guide you about the mode of parameters.

The meaning of swap is interchanging the values. It can be done by using temporary variable or without using it (if the values are integers).

While passing the parameters, there are two ways, call by value/pass by value and call by reference/ pass by reference.

If call by value, then the value gets swapped only inside the function and will not reflected in the calling portion. Call by reference is other way round.
