Question

Csharp. C#

Create a method that accepts 3 parameters length width & height but if any of the three are not passed to the method default values are assigned. Invoke the method passing it 1, 2, 3 and no parameters. To show that it can handle each option.

Answer 1

using System;
public class Test
{
public static void Main()
{
    Console.WriteLine("Enter length,width and height :");
    int length = Convert.ToInt32(Console.ReadLine());
    int width = Convert.ToInt32(Console.ReadLine());
    int height = Convert.ToInt32(Console.ReadLine());
      
    Console.WriteLine("volume = "+method(length,width,height)); // sending inputted parameters
Console.WriteLine("volume = "+method(1)); // sending one parameter
Console.WriteLine("volume = "+method(1,2));// sending two parameters
Console.WriteLine("volume = "+method(1,2,3));// sending three parameters
  
}
public static int method(int length=1,int width=2,int height=3)// default parameters
{
return length*width*height;
}
}

Output:

Enter length,width and height :
4
5
6
volume = 120
volume = 6
volume = 6
volume = 6
