This document discusses pointers and anonymous methods in C#. Pointers allow using unsafe or unmanaged code by storing the address of a variable in memory. A pointer variable declaration specifies the type of variable being pointed to. Anonymous methods provide a way to pass a code block as a delegate parameter without specifying a name. The delegate defines the signature, and the anonymous method defines the implementation inline without a name. Anonymous methods are declared and called similarly to regular methods through a delegate.

- 2. • C# allows using pointer variables in a function of code block when it is marked by the unsafe modifier. The unsafe code or the unmanaged code is a code block that uses a pointer variable. • Pointers • A pointer is a variable whose value is the address of another variable i.e., the direct address of the memory location. similar to any variable or constant, you must declare a pointer before you can use it to store any variable address. • The general form of a pointer declaration is:
- 3. • We discussed that delegates are used to reference any methods that has the same signature as that of the delegate. In other words, you can call a method that can be referenced by a delegate using that delegate object. • Anonymous methods provide a technique to pass a code block as a delegate parameter. Anonymous methods are the methods without a name, just the body. • You need not specify the return type in an anonymous method; it is inferred from the return statement inside the method body. • Writing an Anonymous Method • Anonymous methods are declared with the creation of the delegate instance, with a delegate keyword. For example, • delegate void NumberChanger(int n); ... NumberChanger nc = delegate(int x) { Console.WriteLine("Anonymous Method: {0}", x); };The code block Console.WriteLine("Anonymous Method: {0}", x); is the body of the anonymous method. • The delegate could be called both with anonymous methods as well as named methods in the same way, i.e., by passing the method parameters to the delegate object. • For example, • nc(10);
