1. Explanation:

   #include <iostream>

   using namespace std;

   //class definition

   class Numbers

   {

   private:

   int a;

   int b;

   public:

   //member function declaration

   void readNumbers(void);

   void printNumbers(void);

   int calAddition(void);

   };

   //member function definitions

   void Numbers::readNumbers(void)

   {

   cout<<“Enter first number: “;

   cin>>a;

   cout<<“Enter second number: “;

   cin>>b;

   }

   void Numbers::printNumbers(void)

   {

   cout<<“a= “<<a<<“,b= “<<b<<endl;

   }

   int Numbers::calAddition(void)

   {

   return (a+b);

   }

   //main function

   int main()

   {

   //declaring object

   Numbers num;

   int add; //variable to store addition

   //take input

   num.readNumbers();

   //find addition

   add=num.calAddition();

   //print numbers

   num.printNumbers();

   //print addition

   cout<<“Addition/sum= “<<add<<endl;

   return 0;

   }
