// lec 10 exercise 1

//

// Write a C++ program that:

// - has a class representing a 3-dimensional point

// - has methods to:

//   - return the inner product of two points

//   - handles “<<“, “+”, “-”, “+=”, “-=”, “=”, and copy constructors

//   - uses “const” in all the right places



#include <cstdlib>

#include "ThreeDPoint.h"



int main(int argc, char **argv) {

  ThreeDPoint a, b(1.0, 2.0, 3.0), c(b), d = c, e;



  b += a;

  c += b;

  d -= c;

  e = d + (a + b + c - d);

  a = c - (b + b);

  a = a;



  cout << a << " " << b << " " << c << " " << d << " " << e << endl;

  cout << b.InnerProduct(e) << endl;



  return EXIT_SUCCESS;
