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.
<u>Explanation:</u>
Hey there! you need not to panic about it ,your program didn't have Driver program i.e main program! the correct & working code is given below:
// C++ program to count even digits in a given number .
#include <iostream>
using namespace std;
// Function to count digits
int countEven(int n)
{
int even_count = 0;
while (n > 0)
{
int rem = n % 10;
if (rem % 2 == 0)
even_count++;
n = n / 10;
}
cout << "Even count : "
<< even_count;
if (even_count % 2 == 0 )
return 1;
else
return 0;
}
// Driver Code
int main()
{
int n;
std::cin >>n;
int t = countEven(n);
return 0;
}

Used to lol not anymore tho :p
Answer:
Update the unit firmware.
Explanation:
Updating unit firmware means update the information related to the network that is newly installed on the wireless router. The purpose of this change is to update the devices with new network alterations to work with efficiency and better security. As things are updating on daily basis, so the manufacturer makes the devices, reprogram able to meet the requirement of the future by updating the program in firmware unit. By updating device means this will be to fix the bugs that can be occur in modern era. This will make the device more secure.
These materials are called conductors
