1. It provides a language-neutral development & execution environment.
2. It ensures that an application would not be able to access memory that it is not authorized to access.
3. It provides services to run "managed" applications.
4. The resources are garbage collected.
5. It provides services to run "unmanaged" applications.

switch (id)
{
    case 6: 
        grp = "Grp B"; 
        break;
    
    case 13:
        grp = "Grp D";
        break;
    
    case 1:
        grp = "Grp A";
        break;
    
    case ls > 20:
        grp = "Grp E";
        break ;
    
    case Else:
        grp = "Grp F";
        break;
}

int i = 20 ;
for( ; ; )

    Console.Write(i + " "); 
    if (i >= -10)
        i -= 4;

1. A switch statement can act on numerical as well as Boolean types.
2. A switch statement can act on characters, strings and enumerations types.
3. We cannot declare variables within a case statement if it is not enclosed by { }.
4. The foreach statement is used to iterate through the collection to get the desired information and should be used to change the contents of the collection to avoid unpredictable side effects.
5. All of the expressions of the for statement are not optional.

1. >=
2. !=
3. Not
4. <=
5. <>=

1. Function definitions cannot be nested.
2. Functions can be called recursively.
3. If we do not return a value from a function then a value -1 gets returned.
4. To return the control from middle of a function exit function should be used.
5. Function calls can be nested.

1. It can be used for evaluation of expressions.
2. All elements in the Stack collection can be accessed using an enumerator.
3. It is used to maintain a FIFO list.
4. All elements stored in a Stack collection must be of similar type.
5. Top-most element of the Stack collection can be accessed using the Peek() method.

1. It is a keyed collection.
2. It is a ordered collection.
3. It is an indexed collection.
4. It implements a IDictionaryEnumerator interface in its inner class.
5. The key - value pairs present in a HashTable can be accessed using the Keys and Values properties of the inner class that implements the IDictionaryEnumerator interface.
