Chapter Summary

Summary

• The function keyword is for defining function pointers to be called later just like a function.

• The delegate keyword is for defining delegates. A delegate is the pair of a function pointer and the context that that function pointer to be executed in.

• A delegate can be created from an object and a member function by the syntax &object.member_function.

• Anonymous functions and anonymous delegates (lambdas) can be used in places of function pointers and delegates in expressions.

• There are several syntaxes for lambdas, the shortest of which is for when the equivalent consists only of a single return statement: parameter => expression.

• A more efficient overload of toString() takes a delegate.
