multiplication of two numbers in c++ using class code example

Example 1: c++ program for addition of two numbers using functions

#include <iostream>
using namespace std;

//function declaration
int addition(int a,int b);

int main()
{
	int a,b;	//to store numbers
	int add;	//to store addition 
	
	//read numbers
	cout<<"Enter first number: ";
	cin>>a;
	cout<<"Enter second number: ";
	cin>>b;
	
	//call function
	add=addition(a,b);
	
	//print addition
	cout<<"Addition is: "<<add<<endl;
	
	return 0;
}

//function definition
int addition(int a,int b)
{
	return (a+b);
}

Example 2: C++ multiply

// Program to multiply 2 numbers from user inputs

#include <iostream>
using namespace std;

int main()
{
    double firstNumber, secondNumber, productOfTwoNumbers;
    cout << "Enter two numbers: ";

    // Stores two floating point numbers in variable firstNumber and secondNumber respectively
    cin >> firstNumber >> secondNumber;
 
    // Performs multiplication and stores the result in variable productOfTwoNumbers
    productOfTwoNumbers = firstNumber * secondNumber;  

    cout << "Product = " << productOfTwoNumbers;    
    
    return 0;
}
