// 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;
