Please help with those problems using C++ (term, xterm)

1. Define a structure Point. A point has an x- and a y-coordinate. Write a function double distance(Point a, Point b) that computes the distance from a to b. Write a program that reads the coordinates of the points, calls your function, and displays the result.

2. Write a function Point midpoint(Point a, Point b) that computes the point that is halfway between a and b. Write a program that reads the coordinates of the points, calls your function, and displays the result.
