#Polymorphism in C

##Summary

C is the lengua franca of embedded development. It is incredibly flexible, with built-in language features for imperative, functional, and object-oriented programming. However, getting inheritance to work effectively in standard C requires a little boiler-plate code, of which I've provided an example here.

package main

import (
	"fmt"
	"time"
)

func debounce(interval time.Duration, f func(argList []interface{})) func([]interface{}) {
	timer := &time.Timer{}
	return func(argList []interface{}) {

#Invoking C++ code within a C file

I don't know how useful this is in practice, but today I learned that you can invoke C++ code within a C library if needed. The basic process is to forward-declare C++ structs, then declare the function(s) to be invoked from the C library within an extern "C" block. The file containing these declarations will need to be included in the C source file and in the C++ header and source files. The C file can then be compiled normally with gcc and the C++ source with g++. Finally, the executable will need to be linked with g++ so that C++ operators and keywords will be defined.

This trivial example seems silly, but one can imagine a scenario where a C-library does useful work while taking a function pointer as an argument. The function declared in the extern "C" block here might be accepted as such an argument, and as long as the final
