Multiplication of two numbers in C#

In this tutorial, we will discuss the concept of Multiplication of two numbers in C#

In this topic, we are going to learn how to write a program for multiplying two numbers in C# programming language

Multiplication of two numbers in C#

Multiplication of two numbers using variable

In this program, the user declare and initialize two integer variables num1 and num2. Then two numbers are multiplied using multiplication(*) operator and assigned the result to third (mul) variable

Program 1

// Calculate multiplication of two integers in C# program 
using System; 
public class Multiplication { 
    public static void Main(string[] args) { 
        int num1=35; //declare and initialize variables
        int num2=30; 
        int mul=num1*num2; //Calculate multiplication of two numbers
        Console.WriteLine ("The multiplication of two numbers: "+mul); } }
        //display result on the screen

When the above code is executed, it produces the following result

The multiplication of two numbers: 1050

Program 2

In this program, the user is asked to enter two integer values. These two integers are stored in variables n1 and n2 respectively .Then these two numbers are multiplied using * operator
Then the product of n1 and n2 is evaluated and the result is stored in the mul variable. finally the result is displayed on the screen

// Calculate multiplication of two integers in C# program 
using System; public class Mul_Of_Two_Num { 
    public static void Main(string[] args) { 
        int n1, n2, mul; 
        Console.WriteLine("Find multiplication of two numbers: "); 
        Console.Write("Input number to n1: "); 
        n1=Convert.ToInt32(Console.ReadLine());
        Console.Write("Input number to n2: ");
        n2=Convert.ToInt32(Console.ReadLine());
        mul=n1*n2; 
        Console.WriteLine ("The multiplication of given two integers: "+mul); 
        Console.ReadKey(); } }

When the above code is executed, it produces the following result

Find multiplication of two numbers:
Input number to n1: 12
Input number to n2: 15
The multiplication of given two integers: 180

In the above program, two integer values 12,15 (get input from the user) are stored in n1 and n2. Then n1 and n2 are multiplied using the multiplication(*) operator for calculate product.

Then the result is stored in another variable mul.

Finally, the result is displayed on the screen using display statements in C#
