Answer:
Optional product pricing
Explanation:
<em>Optional product pricing</em> occurs when a product is sold for a much lower price but complementary products or accessories are sold separately to generate profit.
A typical example is in the printer category, printer cartridges are sold separately from the printer when the one in the newly purchased printer runs out. The customer is forced to purchase new cartridges that the company benefits from as profits.
Optional product pricing is a strategy to provide less expensive technology while exploiting the frequent use of accessories to make a substantial profit.
Answer:
#include <bits/stdc++.h>
using namespace std;
int main() {
string email,username,host;//strings to store email,username,hostname..
cout<<"Enter the email address "<<endl;
cin>>email;//taking input of email address..
bool flag=1;
for(int i=0;i<email.length();i++)//iterating over the string email..
{
if(email[i]=='@')//if @ symbol is encountered make flag 0 skip this iteration.
{
flag=0;
continue;
}
if(flag==1)//add to username if flag is 1.
{
username+=email[i];
}
else//add tom host..
host+=email[i];
}
cout<<"The username is "<<username<<endl<<"The host name is "<<host;//printing the username and hostname..
return 0;
}
Explanation:
I have taken three strings to store the email address entered by user ,username and host to store username and host name respectively.Then I am iterating over the string email if @ is encountered then skip that iteration before that keep adding characters to username string and after that keep adding characters to host.
Answer:
Reference
Explanation:
Variables provide reference to the stored data value.
For example:
int i = 0;
Here i is a variable of type int with an initial value of 0. i is a reference to this stored value 0. Now if I want to update the data, I can do so using this reference.
i = 1;
Now the reference is used to manipulate the stored data and change it to 1. In a similar manner all updates to the value can be done using the variable reference.

Answer:
Option 2 i.e., instance methods is the correct answer to the following question.
Explanation:
Because the instance method or function is the function that needed the class object to be called.
<u>For Example:</u>
//header file
#include <iostream>
using namespace std;
//define class
class Test
{
public:
//instance method
void getins()
{
cout<<"I AM Instance method";
}
};
int main()
{
//creating object
Test obj;
//calling of instance method through class object
obj.getins();
}
<u>Output</u>:
I AM Instance method
