Answer:
Following are the statement is given below
if(updateDirection ==1) // check condition
{
++numUsers; // increments the value
}
else
{
--numUsers; // decrement the value
}
Explanation:
Following are the description of statement
- Check the condition in the if block .If the "updateDirection" variable is 1 then then control moves to the if block otherwise control moves to the else block statement.
- In the if block the statement is "++numUsers" it means it increment the value by 1 .
- In the else block the statement is "--numUsers" it means it decrement the value by 1 .
The protocol that should be used for establishing a secure network connection is SSH.
The following information is to be considered:
- SFTP is secure also it is a protocol for file transferring that applied SSH.
- IP, FTP, and DHCP should not be for safety purposes as they are not secure.
- SSH is a secured connection for the remote sites so here the SSH protocol should be used.
Therefore we can conclude that The protocol that should be used for establishing a secure network connection is SSH.
Answer:
// here is code in C++.
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// variables
double num;
// read discriminant
cin>>num;
// calculate square of the input
double result=num*num;
// print the square number
cout<<result<<endl;
return 0;
}
Explanation:
Declare a variable "num".Read the value of "num" from keybord.Then calculate square of the input number.Print the square of input number.
Output:
5
