A Delegate is a variable which holds a reference to a method or Lambda
A Lambda is a method that has no permanent (accessible) name.

A function pointer is called a Delegate in C# (and works the same as a function pointer in C or C++).

A function object is a reference to a method that we can use to set the value of a Delegate.

Is Lambda a function object or a function pointer?

Hint:
A Delegate is a variable which holds a reference to a method or Lambda
Which makes a Lambda a function object.
