Answer:
when user wants duplicate copy of the object
Explanation:
Encapsulation are one of the key foundations of object-oriented programming (OOP). It involves the bundling of data or information with the methods and various techniques which operate on that data.
It can be used in hiding the true values or state of a structured data object that is in a class, preventing unauthorized parties' direct access to them.
The circumstances that can be allowed in returning a reference to the existing Engine is when user wants duplicate copy of the object.
Answer:
<u>Call by reference</u>
In an function if the variables are passed as reference variables this means that the variables are pointing to the original arguments.So the changes made in the function on the reference variables will be reflected back on the original arguments.
For example:-
#include<stdio.h>
void swap(&int f,&int s)
{
int t=f;
f=s;
s =temp;
}
int main()
{
int n,m;
n=45;
m=85;
swap(n,m);
printf("%d %d",m,n);
return 0;
}
the values of m and n will get swapped.
<u>
Call by value</u>
In this program the values of m and n will not get swapped because they are passed by value.So duplicate copies of m and n will be created and manipulation will be done on them.
#include<stdio.h>
void swapv(int f,int s)
{
int t=f;
f=s;
s=temp;
}
int main()
{
int n,m;
n=45;
m=85;
swapv(n,m);
printf("%d %d",n,m);
return 0;
}
(A) the same, by applying styles the same formats are being applied each time.
