Program

using System;
namespace multiply_two_numbers
{
	class MultiplyTwoNumbers
	{
		static void Main(String[] args)
		{
			int a, b;
			Console.Write("Enter first number:\t");
			a = int.Parse(Console.ReadLine());

		}
	}
}

This C# program multiplies two numbers entered by the user and displays the result.

1. using System;

   • Imports the System namespace, which allows the use of built-in functions like Console.WriteLine().

2. namespace multiply_two_numbers

   • Defines a namespace named multiply_two_numbers to group related classes.

3. class MultiplyTwoNumbers

   • Declares a class named MultiplyTwoNumbers, which contains the program logic.

4. static void Main(String[] args)

   • The Main method is the entry point of the program.

5. Declaring Variables:

   • int a, b; → Declares two integer variables to store user input.

6. Reading User Input:

   • Console.Write("Enter first number:\t");

     • Displays a prompt to enter the first number.

   • a = int.Parse(Console.ReadLine());

     • Reads the user input, converts it from string to integer, and stores it in a.

   • Similarly, the second number is read and stored in b.

7. Multiplication Operation:

   • int mul = a * b;
     • Computes the product of a and b and stores it in mul.

8. Displaying the Result:

   • Console.WriteLine("Product of two numbers: " + mul);
     • Prints the multiplication result to the console.

Output

$ mcs MultiplyTwoNumbers.cs 
$ mono MultiplyTwoNumbers.exe 
Enter first number:	12
Enter second number:	9
Product of two numbers: 108
