Relatively easy problems

1. Write a program that reads in two points in ordered pair notation and returns the distance between the two points.
   Examples: (user input in red)

   ~/$ ./prog
   (1,2) (4,6)
   dist = 5

2. Write a program that reads a list of five points (comma-separated, semi-colon terminated) and prints out the distances between each consecutive pair of points.
   Examples: (user input in red)

   ~/$ ./prog
   (2,3), (4,4), (4,1), (3,-1), (0,-2);
   2.23607
   3
   2.23607
   3.16228

   Note: If you get this working, try to then write a program that works for any number of points, not just five!
