Embedded Programming with Modern C++  is highly valuable for each professional programmer.

In the past, embedded and system programming have had their pitfalls, but modern C++ has been designed to be a better language for this type of development, addressing the previous pitfalls/requirements explicitly. What are these requirements? Embedded systems deal with safety-critical systems, meaning they must guarantee high performance combined with limited resources, while also working in parallel.

The scope of this course goes beyond just embedded programming. Developers who write servers, games, or trading systems may especially benefit from this course because they also have to deal with safety-critical systems, high performance, reduced resources, and parallel execution in their jobs.

To get the most out of the course, you only need a basic understanding of C++. Building off this understanding, this course goes over all the essentials of embedded programming with Modern C++.

Let's get started!

Embedded Programming with Modern C++

//userDefinedLiteralExtended.cpp
#include <iostream>
#include <ostream>

namespace Distance{
  class MyDistance{
    public:
      explicit MyDistance(double i):m(i){}

      friend MyDistance operator +(const MyDistance& a, const MyDistance& b){
        return MyDistance(a.m + b.m);
      }
      friend MyDistance operator -(const MyDistance& a,const MyDistance& b){
        return MyDistance(a.m - b.m);
      }

      friend MyDistance operator*(double m, const MyDistance& a){
        return MyDistance(m*a.m);
      }

      friend std::ostream& operator<< (std::ostream &out, const MyDistance& myDist){
        out << myDist.m << " m";
         return out;
      }
    private:
      double m;

  };

  namespace Unit{
    MyDistance operator "" _mi(long double d){
        return MyDistance(1609.344 *d);
      }
    MyDistance operator "" _km(long double d){
      return MyDistance(1000*d);
    }
    MyDistance operator "" _m(long double m){
      return MyDistance(m);
    }
    MyDistance operator "" _ft(long double d){
      return MyDistance(0.348*d);
    }
    MyDistance operator "" _dm(long double d){
      return MyDistance(d/10);
    }
    MyDistance operator "" _cm(long double c){
      return MyDistance(c/100);
    }
  }
}

using namespace Distance::Unit;

int main(){

  std:: cout << std::endl;

  std::cout << "1.0_mi: " << 1.0_mi << std::endl;
  std::cout << "1.0_km: " << 1.0_km << std::endl;
  std::cout << "1.0_m: " << 1.0_m << std::endl;
  std::cout << "1.0_ft: " << 1.0_ft << std::endl;
  std::cout << "1.0_dm: " << 1.0_dm << std::endl;
  std::cout << "1.0_cm: " << 1.0_cm << std::endl;

  std::cout << std::endl;

  std::cout << "0.001 * 1.0_km: " << 0.001 * 1.0_km << std::endl;
  std::cout << "10 * 1_dm: " << 10 * 1.0_dm << std::endl;
  std::cout << "100 * 1.0cm: " << 100 * 1.0_cm << std::endl;

  std::cout << std::endl;
  std::cout << "1.0_km + 2.0_dm +  3.0_dm + 4.0_cm: " << 1.0_km + 2.0_dm +  3.0_dm + 4.0_cm << std::endl;
  std::cout << std::endl;

  Distance::MyDistance work= 63.0_km;
  Distance::MyDistance workPerDay= 2 * work;
  Distance::MyDistance abbrevationToWork= 5400.0_m;
  Distance::MyDistance workout= 2 * 1600.0_m;
  Distance::MyDistance shopping= 2 * 1200.0_m;

  Distance::MyDistance myDistancePerWeek= 4 * workPerDay - 3 * abbrevationToWork + workout + shopping;

  std::cout << "4 * workPerDay - 3 * abbrevationToWork + workout + shopping: " << myDistancePerWeek;

  std::cout << "\n\n";

}



## Explanation
* The mile unit is implemented in lines 31-32.

* The feet unit is implemented in lines 40-41.
* The components `work`, `workPerDay`, `workout`, `abbrevationToWork`, and `shopping` are defined in lines 75-79.

* In line 81, we have computed `myDistancePerWeek` using the components we have defined above.
