Question

Create a class called Pair that has two public integer member variables named "a" and "b", and a public member function named sum() that has no arguments but adds the two member variables together and returns their sum.

Answer 1

Answer. PROGRAM: #include <iostream> 11 To use cout. Class Pair ll Defining class to make Pair of two integers { Public: // Define all variables and Methodl publically to access from outside the scope of class. inta, b; // Declare two integer Member variables. int sumo) ll Defining FUNCTION to calculate Sum of two numbers is return this at this b; 11. Return sum of two numbers حما 3; 11 End of CLASS

int main() 11 Defining maim FUNCTION { Pairp; // Declare a variable of class Pair. pia = 100; // Initialize it with integer value. pub= 200; // Initialize it Integer value Il calculate the sum of two member variable and Check if it is equal to returned value of member Function Sum() or mot if (p.atpib == p. sum) لم Std::cout << "Success!" << std::end); 1. If Both result is equal, print the Message of success, So Function worked correctly. دعا else llotherwise both values Avi mot equal and Function gives wrong sum.

1/ Print the returned value of Function and Actual Summation of two imtge values Std::cout << "p. sum() returns "<<p. Some! <<"instead of" << (pra +pob) << std::endt; ملا returmo 3 11 End of Main Function
