A derived class can stop virtual inheritance by declaring an override as

1. Student[3] = 34;

2. Student s = new Student(); 
   s[3] = 34;

3. Student s = new Student(); 
   Console.WriteLine(s[3]);

4. Console.WriteLine(Student[3]);

5. Student.this s = new Student.this(); 
   s[3] = 34;

1. A class can implement multiple interfaces.
2. Structures cannot inherit a class but can implement an interface.
3. In C#.NET, : is used to signify that a class member implements a specific interface.
4. An interface can implement multiple classes.
5. The static attribute can be used with a method that implements an interface declaration.

1. Data
2. Class
3. Enum
4. Structure
5. Namespace

        }
        static void fun(ref int[] a)
        { 
            for (int i = 0; i < a.Length; i++)
            { 
                a[i] = a[i] * 5; 
                Console.Write(a[ i ] + " "); 
            } 
        } 
    }
