C++ program to add two numbers using class

C-Plus-Plus-Programs

In this article, we will learn how to add two numbers by using the classes. We will define a class that will have functions to take inputs from users,do additions, and display the results.

Explanation: C++ program to add two numbers using class

  • Declare a class with two private members to save the user-provided numbers.
  • Declare 2 public member functions in the class that will be used to take input from users and perform addition.
  • Write the input and addition logic in the declared member functions.
  • In the main() function, declare an object of the class.
  • Using the class object call the member function to take input from the user.
  • Using the class object call the member function to perform the addition on numbers.
  • Display the results of addition.
#include <iostream>
using namespace std;


class AdditionClass
{
	private:
		int num1;
		int num2;
	public:
		
		void InputNumbers();
		int  PerformAddition();
};


void AdditionClass::InputNumbers()
{
	cout<<"Please enter First number: ";
	cin>> num1;
	cout<<"Please enter Second number: ";
	cin>> num2;	
}

int AdditionClass::PerformAddition()
{
	int add = num1 + num2;
	return add;
}


int main()
{
	AdditionClass obj;
	int sum = 0; 

	obj.InputNumbers();
	
	sum = obj.PerformAddition();
	
	
	cout<<"The Sum of the Given numbers "<< obj.num1<< " and" <<  obj.num2 << " is:"<< sum <<endl;
	
	return 0;	
}

Output

Please enter First number: 7
Please enter Second number: 4
The Sum of the Given numbers 7 and 4 is:11
