Answer:
In Python:
def is_power(n):
if n > 2:
n = n/2
return is_power(n)
elif n == 2:
return True
else:
return False
Explanation:
This defines the function
def is_power(n):
If n is greater than 0
if n > 2:
Divide n by 2
n = n/2
Call the function
return is_power(n)
If n equals 2
elif n == 2:
Return True
return True
If n is less than 2
else:
Then, return false
return False
Answer:
The difference between While loop and Do - While loop are explained below.
Explanation:
- While loop : It is a looping procedure in which the statements inside the while loop are executed depending on the condition outside the while before starting the loop.
- If the condition is true then the code inside loop is executed otherwise not.
- Do - While loop: It is a looping procedure in which the statements inside the loop get executed and then the condition at the end of the loop is checked.
- This means even the condition is fails the statements inside the loop are executed once.
- Do while loop name itself suggests that "do the while and then check the condition".
Virus such as a Trojan or Worm, and can cause network crashes.
Answer:
B. Have the user press the appropriate function key combination to enable the wireless radio and then attempt to connect to the wireless network.
Explanation:
Every more often than not, users may experience wireless connection problems. How they respond to these issues solely depends on various factors. When a user like this has issues connecting to the network, first on the list of proper troubleshooting procedures is to check whether the wireless adapter or the function key that turns the wireless radio connection on is toggled on. Sometimes the most obvious causes are the hardest to see. The user should check this first because it will save him or her lots of troubleshooting time if the switch was simply physically disabled.
Answer:
Following are the program in the C++ Programming Language.
//set header file
#include <iostream>
//set namespace
using namespace std;
//define class
class format
{
//set access modifier
public:
//set string type variable
string res;
//define function
void names(string first_name, string last_name)
{
//set if-else if condition to check following conditions
if(first_name.length()>0 && last_name.length()>0)
{
res="Name: "+last_name+", "+first_name;
}
else if(first_name.length()>0 and last_name.length()==0)
{
res="Name: "+first_name;
}
else if(first_name.length()==0 and last_name.length()==0)
{
res="";
}
}
//define function to print result
void out(){
cout<<res<<endl;
}
};
//define main method
int main() {
//set objects of the class
format ob,ob1,ob2;
//call functions through 1st object
ob.names("John","Morris");
ob.out();
//call functions through 2nd object
ob1.names("Jhon","");
ob1.out();
//call functions through 3rd object
ob2.names("", "");
ob2.out();
}
<u>Output</u>:
Name: Morris, John
Name: Jhon
Explanation:
<u>Following are the description of the program</u>:
- Define class "format" and inside the class we define two void data type function.
- Define void data type function "names()" and pass two string data type arguments in its parameter "first_name" and "last_name" then, set the if-else conditional statement to check that if the variable 'first_name' is greater than 0 and 'last_name' is also greater than 0 then, the string "Name" and the following variables added to the variable "res". Then, set else if to check that if the variable 'first_name' is greater than 0 and 'last_name' is equal to 0 then, the string "Name" and the following variable "first_name" added to the variable "res".
- Define void data type function "out()" to print the results of the variable "res".
- Finally, we define main method to pass values and call that functions.
