Answer:
mutator, accessor
Explanation:
Set methods are commonly called mutator methods, and get methods are commonly called accessor methods.
This is because set methods are used to mutate the state of a variable. Get methods, on the other hand are used to access the current state of the variable.
For example:
class Demo{
//Member variable
private int var;
//Accessor method
public int getVar(){
return var;
}
//Mutator method
public void setVar(int value){
var=value;
}
}
Explanation:
We need the DNS(Domain Name System) because it connects to the webpage by using an Internet Protocol address and also used to convert the domain name into IP address on the internet.
Top-level domain is .eu
The top-level domain is also known as TLD, and it is the last part of the domain name.
There are 4 different nameservers.
It depends on the internet connection.
When we search for the valid IP address then it will connect us to that webpage whose IP address we search.
A group of two or more computer systems linked together via communication devices is called: A Network
Answer:
Following are the program in the C++ Programming Language.
#include <iostream>
using namespace std;
//define function for swapping
void SwapValues(int* userVal1,int* userVal2){
//set integer variable to store the value
int z = *userVal1;
//interchange their value
*userVal1 = *userVal2;
//interchange their value
*userVal2 = z;
}
//define main method
int main()
{
//declare variables
int x,y;
//get input from the user
cin>>x>>y;
//Call the method to swap the values
SwapValues(&x,&y);
//print their values
cout<<x<<" "<<y;
return 0;
}
<u>Output</u>:
3 8
8 3
Explanation:
<u>Following are the description of the program</u>.
- Firstly, we define required header file and function 'SwapValues()', pass two pointer type integer variables in argument that is 'userVal1' and 'userVal2'.
- Set integer data type variable 'z' and initialize the value of 'userVal1' in it, then initialize the value of 'userVal2' in 'userVal1' and then initialize the value of 'z' in 'userVal2'.
- Finally, define the main method in which we set two integer type variables and get input from the user in it then, call and pass those variables and print it.
