Product of two numbers

 To find the product of two numbers using C, C++ & Java we have two ways :-

1. Hardcode values in the code.

2. Take input from user.

1. Hardcode values in the code using C.

#include<stdio.h>

int main()

{

    int n1=2,n2=3,product=0;

    product=n1*n2;

    printf("The product of two number is : %d ",product);

    return 0;

}

1. Hardcode values in the code using C++.

#include <iostream>

using namespace std;

int main()

{

    int n1=2, n2=3, product=0;

    

    product = n1*n2;

    cout<<"\nThe product of two numbers  : "<<product;

    return 0;

}

1. Hardcode values in the code using Java.

public class ProductOfNumbers  

{  

    public static void main(String args[])   

    {  

        int n1=2, n2=3 ,product=0;  

        product= n1*n2;  

        printf("The product of two number is : "+product);

    }  

}  

2. Take input from user using C

#include<stdio.h>

int main()

{

    int n1,n2,product=0;

    printf("Enter 2 Number : ");

    scanf("%d%d",&n1,&n2);

    product=n1*n2;

    printf("The product of two numbers n1 and n2 is : %d ",product);

    return 0;

}

2. Take input from user using C++

#include <iostream>

using namespace std;

int main()

{

    int n1, n2, product=0;

    cout<<"Enter any two numbers : ";

    cin>>n1>>n2;

    product = n1*n2;

    

    cout<<""The product of two numbers n1 and n2 is : "<<product;

    return 0;

}

2. Take input from user using Java

import java.util.Scanner;  

public class ProductOfNumbers  

{  

    public static void main(String args[])  

    {  

        int n1, n2, dif=0;  

        Scanner sc = new Scanner(System.in);  

        System.out.print("Enter the first number: ");  

        n1 = sc.nextInt();  

        System.out.print("Enter the second number: ");  

        n2 = sc.nextInt();  

        dif = n1*n2; 

        System.out.println("The product of two numbers n1 and n2 is : " +product);  

    }  

}
