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.

Explain the function of different flags in the 8086<br>​
posledela

Answer:

A flag is a piece of fabric (most often rectangular or quadrilateral) with a distinctive design and colours. It is used as a symbol, a signalling device, or for decoration.8086 has 16-bit flag register, and there are 9 valid flag bits.The FLAGS register is the status register in Intel x86 microprocessors that contains the current state of the processor. This register is 16 bits wide. Its successors, the EFLAGS and RFLAGS registers, are 32 bits and 64 bits wide, respectively. The wider registers retain compatibility with their smaller predecessors.

WAP to enter a multidigit number and find the sum of only even digits in a number.​
daser333 [38]

Following are the program to calculate even digits sum:

<h3>Program:</h3>

#include <iostream>//header file

using namespace std;

int main()//main method

{

   int a[10],s=0,i;//defining an array and an integer variable

   cout<<"Enter array values: ";//print message

   for(i=0;i<=9;i++)//defining a loop that input array value

   {

       cin>>a[i];//input array value

   }

   for(int i=0;i<=9;i++)//defining loop that check array value

   {

       if(a[i]%2==0)//defining if block that checks even number condition value

       {

           s=s+a[i];//adding even number value

       }

   }

   cout<<"The sum of even number is: "<<s;//print even number sum value

   return 0;

}

Program Explanation:

  • Defining a header file.
  • Defining the main method.
  • Inside the main method, an integer array "a", and two integer variable "s,i" is declared.
  • In the next step, a for loop is declared that input the array value, and after input value another loop is declared that check even number value in array.
  • In this loop it adds array value and after adding the value a print method is declared that prints its value.

Output:

Please find the attached file.
